This is a really simple project that shows the usage of Next.js with TypeScript.
Deploy the example using ZEIT Now:
Execute create-next-app
with npm or Yarn to bootstrap the example:
npm init next-app --example with-typescript with-typescript-app
# or
yarn create next-app --example with-typescript with-typescript-app
Download the example:
curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-typescript
cd with-typescript
Install it and run:
npm install
npm run dev
# or
yarn
yarn dev
Deploy it to the cloud with ZEIT Now (Documentation).
This example shows how to integrate the TypeScript type system into Next.js. Since TypeScript is supported out of the box with Next.js, all we have to do is to install TypeScript.
npm install --save-dev typescript
To enable TypeScript's features, we install the type declaratons for React and Node.
npm install --save-dev @types/react @types/react-dom @types/node
When we run next dev
the next time, Next.js will start looking for any .ts
or .tsx
files in our project and builds it. It even automatically creates a tsconfig.json
file for our project with the recommended settings.
Next.js has built-in TypeScript declarations, so we'll get autocompletion for Next.js' modules straight away.
A type-check
script is also added to package.json
, which runs TypeScript's tsc
CLI in noEmit
mode to run type-checking separately. You can then include this, for example, in your test
scripts.
