Decentraland dApps

Common modules for our dApps

Modules

Common redux modules for dApps

Wallet

This module takes care of connecting to MetaMask/Ledger, and insert in the state some useful information like address, network, mana and derivationPath.

Usage

You can use the following selectors importing them from decentraland-dapps/dist/modules/wallet/selectors:

getData = (state: State) => BaseWallet
getError = (state: State) => string
getNetwork = (state: State) =>
  'mainnet' | 'ropsten' | 'rinkeby' | 'kovan' | 'localhost'
getAddress = (state: State) => string
isConnected = (state: State) => boolean
isConnecting = (state: State) => boolean

Also you can hook to the following actions from your reducers/sagas by importing them from decentraland-dapps/dist/modules/wallet/actions:

CONNECT_WALLET_REQUEST
CONNECT_WALLET_SUCCESS
CONNECT_WALLET_FAILURE

Also you can import types for those actions from that same file:

ConnectWalletRequestAction
ConnectWalletSuccessAction
ConnectWalletFailureAction

This is an example of how you can wait for the CONNECT_WALLET_SUCCESS action to trigger other actions:

// modules/something/sagas.ts
import {
  CONNECT_WALLET_SUCCESS,
  ConnectWalletSuccessAction
} from 'decentraland-dapps/dist/modules/wallet/actions'
import { fetchSomethingRequest } from './actions'

export function* saga() {
  yield takeLatest(CONNECT_WALLET_SUCCESS, handleConnectWalletSuccess)
}

function* handleConnectWalletSuccess(action: ConnectWalletSuccessAction) {
  yield put(fetchSomethingRequest())
}

Installation

In order to install this module you will need to add a provider, a reducer and a saga to your dapps.

Provider:

Add the <WalletProvider> as a child of your redux provider. If you use react-router-redux or connected-react-router make sure the <ConnectedRouter> is a child of the <WalletProvider> and not the other way around, like this:

import * as React from 'react'
import * as ReactDOM from 'react-dom'
import { Provider } from 'react-redux'
import { ConnectedRouter } from 'connected-react-router'
import WalletProvider from 'decentraland-dapps/dist/providers/WalletProvider'
import { store, history } from './store'

ReactDOM.render(
  <Provider store={store}>
    <WalletProvider>
      <ConnectedRouter history={history}>{/* Your App */}</ConnectedRouter>
    </WalletProvider>
  </Provider>,
  document.getElementById('root')
)

Reducer:

Import the walletReducer and add it at the root level of your dApp's reducer as wallet, like this:

import { combineReducers } from 'redux'
import { walletReducer as wallet } from 'decentraland-dapps/dist/modules/wallet/reducer'

export const rootReducer = combineReducers({
  wallet
  // your other reducers
})

Saga:

You will need to create a walletSaga and add it to your rootSaga:

import { all } from 'redux-saga/effects'
import { walletSaga } from 'decentraland-dapps/dist/modules/wallet/sagas'

export function* rootSaga() {
  yield all([
    walletSaga()
    // your other sagas here
  ])
}

Storage

The storage module allows you to save parts of the redux store in localStorage to make them persistent and migrate it from different versions without loosing it. This module is required to use other modules like Transaction, Translation and Wallet.

Installation

You need to add a middleware and two reducers to your dApp.

Middleware:

You will need to create a storageMiddleware and add apply it along with your other middlewares:

// store.ts
import { applyMiddleware, compose, createStore } from 'redux'
import { createStorageMiddleware } from 'decentraland-dapps/dist/modules/storage/middleware'
import { migrations } from './migrations'

const composeEnhancers =
  (window as any).__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose

const { storageMiddleware, loadStorageMiddleware } = createStorageMiddleware({
  storageKey: 'storage-key' // this is the key used to save the state in localStorage (required)
  paths: [] // array of paths from state to be persisted (optional)
  actions: [] // array of actions types that will trigger a SAVE (optional)
  migrations: migrations // migration object that will migrate your localstorage (optional)
})

const middleware = applyMiddleware(
  // your other middlewares
  storageMiddleware
)
const enhancer = composeEnhancers(middleware)
const store = createStore(rootReducer, enhancer)

loadStorageMiddleware(store)

Migrations:

migrations looks like

migrations.ts:

export const migrations = {
  2: migrateToVersion2(data),
  3: migrateToVersion3(data)
}

Where every key represent a migration and every method should return the new localstorage data:

function migrateToVersion2(data) {
  return omit(data, 'translations')
}

You don't need to care about updating the version of the migration because it will be set automatically.

Reducer:

You will need to add storageReducer as storage to your rootReducer and then wrap the whole reducer with storageReducerWrapper

import { combineReducers } from 'redux'

import {
  storageReducer as storage,
  storageReducerWrapper
} from 'decentraland-dapps/dist/modules/storage/reducer'

export const rootReducer = storageReducerWrapper(
  combineReducers({
    storage
    // your other reducers
  })
)

Advanced Usage

This module is necessary to use other modules like Transaction, Translation and Wallet, but you can also use it to make other parts of your dApp's state persistent

Learn More

The first parameter of createStorageMiddleware is the key used to store the state data in localStorage (required).

The second parameter is an array of paths from the state that you want to be stored, ie:

const paths = [['invites'][('user', 'name')]]

That will make state.invites and state.user.name persistent. This parameter is optional and you don't have to configure it to use the Transaction and/or Translation modules.

The third parameter is an array of action types that will trigger a SAVE of the state in localStorage, ie:

const actionTypes = [SEND_INVITE_SUCCESS]

This parameter is optional and is and you don't have to configure it to use the Transaction and/or Translation modules.

Transaction

The transaction module allows you to watch for pending transactions and keep track of the transaction history.

Dependencies

This module requires you to install the Storage module in order to work.

Usage

When you have an action that creates a transaction and you want to watch it, you can do with buildTransactionPayload:

import { action } from 'typesafe-actions'
import { buildTransactionPayload } from 'decentraland-dapps/dist/modules/transaction/utils'

// Send Invite

export const SEND_INVITE_REQUEST = '[Request] Send Invite'
export const SEND_INVITE_SUCCESS = '[Success] Send Invite'
export const SEND_INVITE_FAILURE = '[Failure] Send Invite'

export const sendInvitesRequest = (address: string) =>
  action(SEND_INVITE_REQUEST, {
    address
  })

export const sendInvitesSuccess = (txHash: string, address: string) =>
  action(SEND_INVITE_SUCCESS, {
    ...buildTransactionPayload(txHash, {
      address
    }),
    address
  })

export const sendInvitesFailure = (address: string, errorMessage: string) =>
  action(SEND_INVITE_FAILURE, {
    address,
    errorMessage
  })

export type SendInvitesRequestAction = ReturnType<typeof sendInvitesRequest>
export type SendInvitesSuccessAction = ReturnType<typeof sendInvitesSuccess>
export type SendInvitesFailureAction = ReturnType<typeof sendInvitesFailure>

Or buildTransactionWithReceiptPayload if you need the tx event logs

export const sendInvitesSuccess = (txHash: string, address: string) =>
  action(SEND_INVITE_SUCCESS, {
    ...buildTransactionWithReceiptPayload(txHash, {
      address
    }),
    address
  })

It will save the event logs inside { receipt: { logs: [] } } after the tx was confirmed

Then you can use the selectors getPendingTransactions and getTransactionHistory from decentraland-dapps/dist/modules/transaction/selectors to get the list of pending transactions and the transaction history.

Installation

You need to add a middleware, a reducer and a saga to use this module.

Middleware:

Create the transactionMiddleware and apply it

// store.ts
import { createTransactionMiddleware } from 'decentraland-dapps/dist/modules/transaction/middleware'
const transactionMiddleware = createTransactionMiddleware()

const middleware = applyMiddleware(
  // your other middlewares
  transactionMiddleware
)

Reducer:

Add transactionReducer as transaction to your rootReducer

import { combineReducers } from 'redux'
import { transactionReducer as transaction } from 'decentraland-dapps/dist/modules/transaction/reducer'

export const rootReducer = combineReducers({
  transaction
  // your other reducers
})

Saga:

Add transactionSaga to your rootSaga

import { all } from 'redux-saga/effects'
import { transactionSaga } from 'decentraland-dapps/dist/modules/transaction/sagas'

export function* rootSaga() {
  yield all([
    transactionSaga()
    // your other sagas
  ])
}

Advanced Usage

You can make your reducers listen to confirmed transactions and update your state accordingly

Learn More

Taking the example of the SEND_INVITE_SUCCESS action type shown in the Usage section above, let's say we want to decrement the amount of available invites after the transaction is mined, we can do so by adding the FETCH_TRANSACTION_SUCCESS action type in our reducer:

// modules/invite/reducer
import { AnyAction } from 'redux'
import { loadingReducer } from 'decentraland-dapps/dist/modules/loading/reducer'
import {
  FETCH_INVITES_REQUEST,
  FETCH_INVITES_SUCCESS,
  FETCH_INVITES_FAILURE,
  FetchInvitesSuccessAction,
  FetchInvitesFailureAction,
  FetchInvitesRequestAction,
+  SEND_INVITE_SUCCESS
} from './actions'
+ import { FETCH_TRANSACTION_SUCCESS, FetchTransactionSuccessAction } from 'decentraland-dapps/dist/modules/transaction/actions';

export type InviteState = {
  loading: AnyAction[]
  data: {
    [address: string]: number
  }
  error: null | string
}

export type InviteReducerAction =
  | FetchInvitesRequestAction
  | FetchInvitesSuccessAction
  | FetchInvitesFailureAction
+  | FetchTransactionSuccessAction

export const INITIAL_STATE: InviteState = {
  loading: [],
  data: {},
  error: null
}

export function invitesReducer(
  state: InviteState = INITIAL_STATE,
  action: InviteReducerAction
): InviteState {
  switch (action.type) {
    case FETCH_INVITES_REQUEST: {
      return {
        ...state,
        loading: loadingReducer(state.loading, action)
      }
    }
    case FETCH_INVITES_SUCCESS: {
      return {
        loading: loadingReducer(state.loading, action),
        data: {
          ...state.data,
          [action.payload.address]: action.payload.amount
        },
        error: null
      }
    }
    case FETCH_INVITES_FAILURE: {
      return {
        ...state,
        loading: loadingReducer(state.loading, action),
        error: action.payload.errorMessage
      }
    }
+    case FETCH_TRANSACTION_SUCCESS: {
+      const { transaction } = action.payload
+      switch (transaction.actionType) {
+        case SEND_INVITE_SUCCESS: {
+          const { address } = (transaction as any).payload
+          return {
+            ...state,
+            data: {
+              ...state.data,
+              [address]: state.data[address] - 1
+            }
+          }
+        }
+        default:
+          return state
+      }
+    }
    default: {
      return state
    }
  }
}

Translation

This module allows you to do i18n.

Dependencies

This module has an optional dependency on Storage module to cache translations and boot the application faster. To learn more read the Advanced Usage section of this module.

Usage

Using the helper t() you can add translations to your dApp

import * as React from 'react'
import { t } from 'decentraland-dapps/dist/modules/translation/utils'

export default class BuyButton extends React.PureComponent {
  render() {
    return <button>{t('but_page.buy_button')}</button>
  }
}

Then you just have to provide locale files like this:

en.json

{
  "buy_page": {
    "buy_button": "Buy"
  }
}

es.json

{
  "buy_page": {
    "buy_button": "Comprar"
  }
}

Yon can dispatch the changeLocale(locale: string) action from decentraland-dapps/dist/modules/translation/actions to change the language

Installation

You will need to add a provider, a reducer and a saga to use this module

Provider:

Add the <TranslationProvider> as a child of your redux provider, passing the locales that you want to support. If you use react-router-redux or connected-react-router make sure the <ConnectedRouter> is a child of the <TranslationProvider> and not the other way around, like this:

import * as React from 'react'
import * as ReactDOM from 'react-dom'
import { Provider } from 'react-redux'
import { ConnectedRouter } from 'connected-react-router'
import TranslationProvider from 'decentraland-dapps/dist/providers/TranslationProvider'
import { store, history } from './store'

ReactDOM.render(
  <Provider store={store}>
    <TranslationProvider locales={['en', 'es', 'ko', 'zh']}>
      <ConnectedRouter history={history}>{/* Your App */}</ConnectedRouter>
    </TranslationProvider>
  </Provider>,
  document.getElementById('root')
)

Reducer:

Add the translationReducer as translation to your rootReducer:

import { combineReducers } from 'redux'
import { translationReducer as translation } from 'decentraland-dapps/dist/modules/translation/reducer'

export const rootReducer = combineReducers({
  translation
  // your other reducers
})

Saga:

Create a translationSaga and add it to your rootSaga. You need to provide an object containing all the translations, or a function that takes the locale and returns a Promise of the translations for that locale (you can use that to fetch the translations from a server instead of bundling them in the app). Here are examples for the two options:

Bundling the translations in the dApp:

en.json

{
  "buy_page": {
    "buy_button": "Buy"
  }
}

es.json

{
  "buy_page": {
    "buy_button": "Comprar"
  }
}

translations.ts

const en = require('./en.json')
const es = require('./es.json')
export { en, es }

sagas.ts

import { all } from 'redux-saga/effects'
import { createTranslationSaga } from 'decentraland-dapps/dist/modules/translation/sagas'
import * as translations from './translations'

export const translationSaga = createTranslationSaga({
  translations
})

export function* rootSaga() {
  yield all([
    translationSaga()
    // your other sagas
  ])
}

Fetching translations from server

sagas.ts

import { all } from 'redux-saga/effects'
import { createTranslationSaga } from 'decentraland-dapps/dist/modules/translation/sagas'
import { api } from 'lib/api'

export const translationSaga = createTranslationSaga({
  getTranslation: locale => api.fetchTranslations(locale)
})

export function* rootSaga() {
  yield all([
    translationSaga()
    // your other sagas
  ])
}

Read the Advanced Usage section below to learn how to cache translations and make your application boot faster.

Advanced Usage

You can use the Storage module to cache translations (read 2. Fetching translations from server above).

Learn More

After installing the Storage module you can persist the translations by adding 'translation' to your storage middleware paths:

// store.ts

const { storageMiddleware, loadStorageMiddleware } = createStorageMiddleware({
  storageKey: 'my-dapp-storage',
  paths: ['translation']
})

This will store the translation module in localStorage, so next time your application is started it will boot with all the translations populated before even fetching them from the server.

Analytics

The analytics module let's integrate Segment into your dApp.

You need to have the Wallet module installed in order to send identify events.

To send track events, add an analytics.ts file and require it from your entry point, and use the add() helper to add actions that you want to track:

// analytics.ts
import { add } from 'decentraland-dapps/dist/modules/analytics/utils'
import {
  CREATE_VOTE_SUCCESS,
  CreateVoteSuccessAction
} from 'modules/vote/actions'

add(CREATE_VOTE_SUCCESS, 'Vote', (action: CreateVoteSuccessAction) => ({
  poll_id: action.payload.vote.poll_id,
  option_id: action.payload.vote.option_id,
  address: action.payload.wallet.address
}))

The first parameter is the action type that you want to track (required).

The second parameter is the event name for that action (it will show up with that name in Segment). If none provided the action type will be used as the event name.

The third parameter is a function that takes the action and returns the data that you want to associate with that event (it will be sent to Segment). If none is provided the whole action will be sent.

Installation

You need to apply a middleware and a saga to use this module

Middleware:

// store.ts
import { createAnalyticsMiddleware } from '@dapps/modules/analytics/middleware'

const analyticsMiddleware = createAnalyticsMiddleware('SEGMENT WRITE KEY')

const middleware = applyMiddleware(
  // your other middlewares
  analyticsMiddleware
)
const enhancer = composeEnhancers(middleware)
const store = createStore(rootReducer, enhancer)

Saga:

import { all } from 'redux-saga/effects'
import { analyticsSaga } from 'decentraland-dapps/dist/modules/analytics/sagas'

export function* rootSaga() {
  yield all([
    analyticsSaga()
    // your other sagas
  ])
}

This uses by defualt the '@@router/LOCATION_CHANGE' action type to track page changes. If you need to use a different action type, you can do the following:

import { all } from 'redux-saga/effects'
import { createAnalyticsSaga } from 'decentraland-dapps/dist/modules/analytics/sagas'

const analyticsSaga = createAnalyticsSaga({
  LOCATION_CHANGE: 'custom action type'
})

export function* rootSaga() {
  yield all([
    analyticsSaga()
    // your other sagas
  ])
}

Advanced Usage

You can use the same redux action type to generate different Segment events if you pass a function as the second parameter instead of a string:

add(AUTHORIZE_LAND_SUCCESS, action =>
  action.isAuthorized ? 'Authorize LAND' : 'Unauthorize LAND'
)

Loading

The loading module is used to keep track of async actions in the state.

Usage

You can use the selectors isLoading(state) and isLoadingType(state, ACTION_TYPE) from decentraland-dapps/dist/modules/loading/selectors to know if a domain has pending actions or if a specific action is still pending

In order to use these selectors you need to use the loadingReducer within your domain reducers, here is an example:

import {
  loadingReducer,
  LoadingState
} from 'decentraland-dapps/dist/modules/loading/reducer'
import {
  FETCH_INVITES_REQUEST,
  FETCH_INVITES_SUCCESS,
  FETCH_INVITES_FAILURE,
  FetchInvitesSuccessAction,
  FetchInvitesFailureAction,
  FetchInvitesRequestAction
} from './actions'

export type InviteState = {
  loading: LoadingState
  data: {
    [address: string]: number
  }
  error: null | string
}

export const INITIAL_STATE: InviteState = {
  loading: [],
  data: {},
  error: null
}

export type InviteReducerAction =
  | FetchInvitesRequestAction
  | FetchInvitesSuccessAction
  | FetchInvitesFailureAction

export function invitesReducer(
  state: InviteState = INITIAL_STATE,
  action: InviteReducerAction
): InviteState {
  switch (action.type) {
    case FETCH_INVITES_REQUEST: {
      return {
        ...state,
        loading: loadingReducer(state.loading, action)
      }
    }
    case FETCH_INVITES_SUCCESS: {
      return {
        loading: loadingReducer(state.loading, action),
        data: {
          ...state.data,
          [action.payload.address]: action.payload.amount
        },
        error: null
      }
    }
    case FETCH_INVITES_FAILURE: {
      return {
        ...state,
        loading: loadingReducer(state.loading, action),
        error: action.payload.errorMessage
      }
    }
    default: {
      return state
    }
  }
}

Now we can for example use the selector isLoadingType(state.invite.loading, FETCH_INVITES_REQUEST) to know if that particular action is still pending, or isLoading(states.invite) to know if there's any pending action for that domain.

Also, all the pending actions are stored in an array in state.invite.loading so we can use that information in the UI if needed (i.e. disable a button)

Modal

Leverages redux state and provides actions to open and close each modal by name. It provides a few simple actions:

openModal(name: string, metadata: any = null)
closeModal(name: string)
closeAllModals()
toggleModal(name: sgtring)

It also provides a selector to get the open modals:

getOpenModals(state): ModalState

Installation

In order to use this module you need to add a reducer and a provider.

Provider:

Add the <ModalProvider> as a parent of your routes. It takes an object of { {modalName: string]: React.Component } as a prop (components). It'll use it to render the appropiate modal when you call openModal(name: string)

import * as React from 'react'
import * as ReactDOM from 'react-dom'
import { Provider } from 'react-redux'
import { ConnectedRouter } from 'connected-react-router'
import ModalProvider from 'decentraland-dapps/dist/providers/ModalProvider'
import * as modals from 'components/Modals'
import { store, history } from './store'

ReactDOM.render(
  <Provider store={store}>
    <ModalProvider components={modals}>
      <ConnectedRouter history={history}>{/* Your App */}</ConnectedRouter>
    </ModalProvider>
  </Provider>,
  document.getElementById('root')
)

where modals could look like this:

// components/Modals/index.ts

export { default as HelpModal } from './HelpModal'

Each modal will receive the properties defined on the ModalComponent type, found on modules/modal/types, so for example:

import { Modal } from 'decentraland-ui'
import { ModalProps } from 'decentraland-dapps/dist/modules/modal/types'

type HelpModalProps = ModalProps & {
  // Some custom props, maybe from a container
}

export default class HelpModal extends React.Component<HelpModalProps> {
  render() {
    const { name, metadata, onClose } = this.props
    // The Modal component here can be whatever you like, just make sure to call onClose when you want to close it, to update the state
    // For more examples check the advanced usage
    return <Modal open={true} className={name} onClose={onClose} />
  }
}

If want to use decentraland-ui's Modal but you don't want to repeat the open, className and onClose props, you can use this module's Modal

Reducer:

Add the modalReducer as modal to your rootReducer:

import { combineReducers } from 'redux'
import { modalReducer as modal } from 'decentraland-dapps/dist/modules/modal/reducer'

export const rootReducer = combineReducers({
  modal
  // your other reducers
})

Advanced Usage

You can have add more strict typing to the actions:

Learn More

The modal actions allow for a generic type for the name. So say you want to type the name of your available modals, you can create a `modal` module in your dApp and add the following files:

Types:

// modules/types/actions.ts
import * as modals from 'components/Modals' // same import as the one use for <ModalProvider />

export ModalName = keyof typeof modals

Actions:

// modules/modal/actions.ts
import { getModalActions } from 'decentraland-dapps/dist/modules/modal/actions'
import { ModalName } from './types'

const { openModal, closeModal, toggleModal } = getModalActions<ModalName>()

export * from 'decentraland-dapps/dist/modules/modal/actions'
export { openModal, closeModal, toggleModal }

Lib

Common libraries for dApps

API

The BaseAPI class can be extended to make requests and it handles the unwrapping of responses by decentraland-server

Usage

// lib/api
import { BaseAPI } from 'decentraland-dapps/dist/lib/api'

const URL = 'http://localhost/api'

export class API extends BaseAPI {
  fetchSomething() {
    return this.request('get', '/something', {})
  }
}

export const api = new API(URL)

Containers

Common containers for dApps

Navbar

The <Navbar> container can be used in the same way as the <Navbar> component from decentraland-ui but it's already connected to the redux store. You can override any NavbarProp if you want to connect differently, and you can pass all the regular NavbarProps to it.

Dependencies

This container requires you to install the Wallet. It also has support for i18n out of the box if you include the Translation module.

Usage

This is an example of a SomePage component that uses the <Navbar> container:

import * as React from 'react'

import { Container } from 'decentraland-ui'
import Navbar from 'decentraland-dapps/dist/containers/Navbar'

import './SomePage.css'

export default class SomePage extends React.PureComponent {
  static defaultProps = {
    children: null
  }

  render() {
    const { children } = this.props

    return (
      <>
        <Navbar />
        <div className="SomePage">
          <Container>{children}</Container>
        </div>
      </>
    )
  }
}

This <Navbar> will show the user's blockie and mana balance because it is connected to the store.

i18n

If you are using the Translation module, the Navbar contatiner comes with support for the 6 languages supported by the library.

Advanced Usage

You can override any of the default translations for any locale if you need to

Learn More

Say you want to override some translations in English, just include any or all of the following translations in your en.json locale file:

{
  "@dapps": {
    "navbar": {
      "account": {
        "connecting": "Connecting...",
        "signIn": "Sign In"
      },
      "menu": {
        "agora": "Agora",
        "blog": "Blog",
        "docs": "Docs",
        "marketplace": "Marketplace"
      }
    }
  }
}

Footer

The <Footer> container can be used in the same way as the <Footer> component from decentraland-ui but it's already connected to the redux store. You can override any FooterProps if you want to connect differently, and you can pass all the regular FooterProps to it.

Dependencies

The <Footer> container has support for i18n out of the box if you include the Translation module.

Usage

This is an example of a SomePage component that uses the <Footer> container:

import * as React from 'react'

import { Container } from 'decentraland-ui'
import Navbar from 'decentraland-dapps/dist/containers/Navbar'

import './SomePage.css'

export default class SomePage extends React.PureComponent {
  render() {
    const { children } = this.props
    return (
      <>
        <div className="SomePage">
          <Container>{children}</Container>
        </div>
        <Footer locales={['en', 'es']} />
      </>
    )
  }
}

This <Footer> will show only English and Spanish as the options in the language dropdown. If you don't provide any it will use only English.

i18n

If you are using the Translation module, the Footer contatiner comes with support for the 6 languages supported by the library.

Advanced Usage

You can override any of the default translations for any locale if you need to

Learn More

Say you want to override some translations in English, just include any or all of the following translations in your en.json locale file:

SignInPage

The <SignInPage> container can be used in the same way as the <SignIn> component from decentraland-ui but it's already connected to the redux store. You can override any SignInProp if you want to connect differently, and you can pass all the regular SignInProps to it.

Dependencies

This container requires you to install the Wallet. It also has support for i18n out of the box if you include the Translation module.

Usage

You can import the <SignInPage> container and use it on your routes:

import * as React from 'react'
import { Switch, Route } from 'react-router-dom'

import SignInPage from 'decentraland-dapps/dist/containers/SignInPage'

//...

<Switch>
  <Route exact path='/' component={...} />
  {/* your dapps routes... */}
  <Route exact path='/sign-in' component={SignInPage} />
</Switch>

i18n

If you are using the Translation module, the SignInPage contatiner comes with support for the 6 languages supported by the library.

Advanced Usage

You can override any of the default translations for any locale if you need to

Say you want to override some translations in English, just include any or all of the following translations in your en.json locale file:

{
  "@dapps": {
    "sign_in": {
      "connect": "Connect",
      "connected": "Connected",
      "connecting": "Connecting...",
      "error": "Could not connect to wallet.",
      "get_started": "Get Started",
      "options": {
        "desktop": "You can use the {metamask_link} extension or a hardware wallet like {ledger_nano_link}.",
        "mobile": "You can use mobile browsers such as {coinbase_link} or {imtoken_link}."
      }
    }
  }
}

Modal

The <Modal> it's a shorthand for some common features used by modals provided to ModalProvider.

Usage

import * as React from 'react'
import Modal from 'decentraland-dapps/dist/containers/Modal'

export default class MyComponent extends React.PureComponent {
  render() {
    return (
      const { name } = this.props

      <Modal name={name} {/* Other Modal props from decentraland ui */>
        <Modal.Header>
        </Modal.Header>
        <Modal.Description>
        </Modal.Description>
      </Modal>
    )
  }
}

Behind the scenes Modal is setting the following properties:

open={true}
className={name}
size="small"
onClose={/*close the modal by name*/}

EtherscanLink

The <EtherscanLink> can be used to link a transaction hash to Etherscan.io, and it connects to the redux store to know on which network the user is on.

Dependencies

This container requires you to install the Wallet module

Usage

import * as React from 'react'
import EtherscanLink from 'decentraland-dapps/dist/containers/EtherscanLink'

export default class MyComponent extends React.PureComponent {
  render() {
    return (
      <p>
        You sent an <EtherscanLink txHash={'0x...'}>invite</EtherscanLink>
      </p>
    )
  }
}

Components

Common Components for dApps

Intercom

The <Intercom> will add an intercom widget to your app

Usage

import * as React from 'react'
import Intercom from 'decentraland-dapps/dist/components/Intercom'

export default class MyComponent extends React.PureComponent {
  render() {
    return (
      <div>
        {/* (...) */}
        <Intercom
          appId={YOUR_APP_ID}
          data={/*optional data sent to intercom */}
        />
      </div>
    )
  }
}
