Blues Notehub JS

The notehub-js library is a JavaScript implementation for communicating with the Blues Notehub API generated by the OpenAPI Generator tool.

This library is auto-generated via the openapi.yaml file from the Blues Wireless Notehub project and published to npm for ease of use in JavaScript-based projects that need to interact with Notehub.io.

Installation

Using npm:

$ npm install @blues-inc/notehub-js

Using yarn:

$ yarn add @blues-inc/notehub-js

Once the package is installed, you can import the library using import or require:

import

import * as NotehubJs from "@blues-inc/notehub-js";

const defaultClient = NotehubJs.ApiClient.instance;

NOTE: Using import to access the library in a TypeScript project currently will cause an error because there is not yet a @types file for it. To make the error disappear, declare the module in a file with a .d.ts extension. declare module '@blues-inc/notehub-js';

require

const NotehubJs = require("@blues-inc/notehub-js");

const defaultClient = NotehubJs.ApiClient.instance;

Sample Code

Here is an example of how to fetch all devices associated with a particular Notehub project.

The api-key variable declared below is an X-SESSION-TOKEN authentication token required for all Notehub API requests.

It can be obtained in two ways:

Manually cURL the token from the command line

Using the command line, a user can request a new token from the Notehub API /auth/login endpoint using a Notehub username and password in the body of the request.

Use NotehubJs.AuthorizationApi login

Using this library, a user can programmatically call the Notehub API's /auth/login endpoint via the NotehubJs.AuthorizationApi's login() method while supplying a Notehub username and password in the loginRequest object.

Then supply the newly generated authentication token to whatever method the library needs, by setting it equal to: api_key.apiKey = "YOUR API KEY"; in the code.

NOTE: Be aware that all Notehub API calls made using the Notehub JS library utilize your account's Consumption Credits (CCs). For > more information, please consult our pricing page.

import * as NotehubJs from "@blues-inc/notehub-js";

let defaultClient = NotehubJs.ApiClient.instance;

// Configure API key authorization: api_key
let api_key = defaultClient.authentications["api_key"];
api_key.apiKey = "YOUR API KEY";

let apiInstance = new NotehubJs.ProjectApi();
let projectUID = "app:2606f411-dea6-44a0-9743-1130f57d77d8;"; // String |
let opts = {
  pageSize: 50, // Number |
  pageNum: 1, // Number |
};

// Want to use async/await? Add the 'async' keyword to your outer function/method.
apiInstance.getProjectDevices(projectUID, opts).then(
  (data) => {
    console.log(
      "API called successfully. Returned data: " + JSON.stringify(data)
    );
  },
  (error) => {
    console.error(error);
  }
);

Real World Use Cases of Notehub JS Library

As this library gains adoptions, we'll continue to provide new links to repos where this library being used in real world projects.

Indoor Floor Level Tracker Project

If you'd like to see examples of this library being used in real-world applications, check out this indoor floor-level tracker project in the Blues App Accelerator repo on GitHub.

The files that deserve special attention are:

ServiceLocatorServer.ts - this file makes the variety of services composing the backend logic of the application discoverable to each other. For DRY-er code, the Notehub JS library's instances were created and passed to the various services that would require them to fetch and update data via the Notehub API. An instance of the Notehub JS client is created via const notehubJsClient = NotehubJs.ApiClient.instance, and passed to the getDataProvider() and getAttributeStore() services that will need to interact with the Notehub API to perform their duties.
NotehubDataProvider.ts - this file is responsible for fetching data from the Notehub API for the application to display. It calls the project API's getProjectFleetDevices() and getProjectEvents() methods, and the fleet API's getFleetEnvironmentVariables() method as well.
NotehubAttributeStore.ts - this file sends updates to the Notehub API from the application like updated device name or updated environment variables. It calls two of the environment variable API's methods: putDeviceEnvironmentVariables() and putFleetEnvironmentVariables().

Further Library Documentation & Code Examples

If you want more information, code examples of how to use each of the Notehub API endpoints are located in the src/docs/ folder and available on the Blues Developer Experience site.

Each API (device, event, fleet, etc.) had a .md file displaying:

All the HTTP methods it supports,
A full URL string of what the HTTP request looks like (including required and optional parameters),
An example of how to implement the code for a particular method inside of a JavaScript application,
A sample return type from a particular method,
Required authorization to access the method.

Project Structure

As this project is partially generated via the OpenAPI Generator tool, it has a rather unique structure and some important files to be aware of.

Root Folder

Files and folders to be aware of in the root of the project.

The .github/ folder holds the helper scripts and GitHub Actions workflows that automate common tasks in the repo. See the Modifying the Project section for further information.
The openapi.yaml is a key player for this project: it provides the documentation of all the Notehub API endpoints that the OpenAPI Generator tool uses to build the library - without this file, the project doesn't exist.

NOTE: Later, the filter-deprecated-params.js file and openapi.filtered.yaml file were added to the SDK library. The filter-deprecated-params.js file makes a copy of the openapi.yaml file and removes any query params that have been marked as deprecated. Eliminating these deprecated params makes the generated SDK docs and sample code easier to understand, and free from potentially confusing elements that could mislead users.

The libTemplate/ folder is the JavaScript library template that the OpenAPI generator uses to generate the src/ folder where auto-generated JS library is created.

NOTE: In many scenarios, downloading the OpenAPI Generator library template is not necessary, but there were some minor modifications needed in the template's generation to handle null and undefined values in the same way that the original Notehub API handles them. Being able to download and modify those files offered the fine-grained control needed when generating the JS library code.

If you ever need a fresh copy of the JS library template, run the following script command in the terminal to download it:
$ npm run downloadJsTemplate

The config.json file is a configuration file of additional properties used by the OpenAPI Generator and its JavaScript library template to define certain variables like license type, project name, project version, etc.
The .husky/ folder is a set of pre-commit hooks that Husky runs on all files staged for commit to GitHub. It currently runs them through our Prettier file formatting tool via the pretty-quick npm library.

`src/` Folder

The src/ folder inside the root of the project contains the contents of the auto-generated notehub-js library that is eventually published to npm, including:

The docs/ folder documenting how to access the API endpoints via the library,
The internal src/ folder that holds the JavaScript-based api and model files for each endpoint,
The test/ folder for unit tests,
And the dist/ folder contains the packaged up final version of the library shipped to npm.

NOTE: Do not modify the files in the src/src/ folder and the src/README.md - these are all auto-generated by the OpenAPI Generator tool and the next time the generator command is run to update the library any manual changes will be overwritten.

Repo Usage

Instructions for how to modify or run this project locally.

Initial Project Setup & Dependencies

This project uses Node.js as a runtime, npm as a package manager, and Volta as a way of enforcing consistent versions of all JavaScript-based tools. You can install these dependencies by completing the steps below.

Install Volta by following its installation instructions.
Run the command below in a terminal to install the appropriate versions of both Node.js and npm.

$ volta install node npm

Navigate to the root of the folder in your terminal or command prompt and run npm install, which installs the repo's npm dependencies, including the prettier, pretty-quick, and husky libraries which will format any files staged for commit according to our coding style as defined in the .prettierrc file.

$ npm install

The project also uses the OpenAPI Generator's CLI tool, so it's recommended to install that tool globally through the terminal.

$ npm install @openapitools/openapi-generator-cli -g

Now you should be ready to make any changes or modifications.

Modifying the Project

Most of the files stored at the root of this project should require little to no modifications.

The lib/template folder holds the JavaScript generator template files the OpenAPI Generator tool relies upon to build its library in the src/ folder.

The .github/ folder holds helper scripts and a set of GitHub Actions workflows that automate common tasks like creating PRs out of new branches, running automated tests, and publishing new releases to npm.

The openapi.yaml file is a copy of the one in the Notehub repo (a private Blues repository). Anytime a new version of Notehub.io is deployed and the openapi.yaml file there is updated, a fresh copy of that file is added to this project in a new branch via a GitHub Actions workflow.

The filter-deprecated-params.js file, contained within the .github/scripts/ directory makes a copy of the openapi.yaml file called openapi.filtered.yaml which removes any query params marked as deprecated in the original openapi.yaml to prevent confusion for users about which query params are current vs deprecated. The openapi.filtered.yaml is what ends up being used to generate the Notehub JS SDK library.

The config.json file is the one that will require slight changes before a new version of the library is released to npm. The next section will elaborate further.

Updating the Auto-Generated notehub-js Library

When the openapi.yaml file is updated in the original Notehub repo which this library supports, the updated file is copied over into a new feature branch in this repo through the magic of GitHub Actions.

When this occurs, it's time to regenerate the notehub-js JavaScript library based on the newly updated openapi.yaml.

To regenerate the notehub-js library:

Git clone the repo from GitHub.

$ git clone git@github.com:blues/notehub-js.git

Check out the newly created remote branch from GitHub locally. (It will be named something like feat-XYZ.)
Update the config.json file at the project's root so the projectVersion parameter is incremented (please follow semantic versioning practices here).
At the root of the project, run the following script command from your terminal:

$ npm run filterOpenapi

This command will make a copy of the openapi.yaml file named openapi.filtered.yaml which has removed any query parameters marked as deprecated from the openapi.yaml file. Removing these now deprecated params ensures the generated SDK docs and sample code is clear,up-to-date, and free from potentially confusing artifacts to trip up users.

Still at the root of the project, run the following script command from your terminal:

$ npm run generateDocs

This command will kick off the OpenAPI Generator tool to generate a new copy of the library inside of the src/ folder, which can then be merged to the main repo branch and released to npm.

NOTE: If you'd like more information about what exactly the generateDocs script is doing with its OpenAPI generator CLI commands, you can see the documentation for them here.

Testing the Library Locally

If you'd like to test some changes you've made to the notehub-js API locally before submitting a new PR to the repo, follow steps 1 - 4 above and then:

Navigate into the src/ folder in the project and install and build the newly generated project.

Install first.

$ npm install

Build next.

$ npm run build

Still inside the src/ folder, link it globally with npm.

$ npm link

Then go to the local JavaScript project where you want to use it, and add it as a local dependency in the project's package.json file with a relative path to the local library on your machine. The file path will probably look something like:

 "dependencies": {
    "../../notehub-js": "^1.0.5"
 }

Install the module inside of your project.

npm install

Import the library using import or require as documented above in your application code and test it out.

All of these directions are also available in the auto-generated README.md in the src/ folder as well, for reference.

NOTE: Even testing locally, you will need an X-SESSION-TOKEN (this is the 'api-key' referenced in the code examples). See these directions on the Blues Developer Experience site to generate one.

Deploying notehub-js to npm

Although many of the processes around this repository are automated with GitHub Actions, publishing an updated version of the repo requires some human intervention as well.

Below are the necessary steps to take a new version of the openapi.yaml file and make it ready to deploy to npm.

Steps to Publish an Updated npm Version of Repo

Adjust the version number ("projectVersion") in the config.json file. (Failure to adjust "projectVersion" will cause the release to npm to fail; the same version number can't be published more than once.)
Run npm run filterOpenapi to create a fresh version of the openapi.filtered.yaml file that removes all deprecated query params from the original openapi.yaml file.
Run npm run generateDocs to generate new docs from the openapi.filtered.yaml file.
Commit and push the changes to a new branch in GitHub and open a new pull request when the branch is ready for review. See the contribution documentation for further details around a good PR and commit messages.
Get the PR approved and merged to main.
Create a new release with a tag following the semantic versioning style of [vX.X.X] and publish the release. For example: a new release with a tag named v1.0.2.
After the GitHub Actions workflow publish-npm.yml has successfully deployed the latest version of notehub-js to npm, copy the changelog notes from the GitHub Action step Generate release changelog.
Paste those notes into the appropriate release tag in the repo.

Copy the formatted changelog notes from the GH Action workflow run.

Paste the notes into the newest release tag.

Steps to Publish a Beta Version of Repo to npm

During the course of the development cycle, it may make sense to have beta versions of a repo available on npm for testing purposes. These versions of the notehub-js repo are considered unstable and should not be used long term in production apps, they are meant for internal testing of new features before they're ready for public consumption. Here are the steps to deploy a beta version of the SDK to npm:

Create a new feature branch with the name test-release-BRANCH-NAME-OF-CHOICE, and modify the openapi.yaml file. Commit that new branch back to the Notehub JS repo.
Once committed, two GitHub Action workflows will detect the branch name contains test-release-* and one will create a new PR to document that a new beta release of the Notehub JS SDK is happening, and the other will actually perform the release automatically (update the project version with a beta.XX tag, regenerate the SDK with the new openapi.yaml file, publish it as a beta version to npm, commit the newly update project version back to the PR, etc.)

Now, anyone can download the beta version of the Notehub JS with the following command:

npm install @blues-inc/notehub-js@1.0.23-beta.XX

You can see all available project versions by visiting the Notehub JS npm page and clicking the "Versions" tab.
