instant-client

This houses Instant's javascript monorepo! Here's the lay of the land:

  1. www/
    1. This is a nextjs app. It’s the frontend for instantdb.com, including the dashboard and docs.
  2. packages/
    1. These are where our client libraries live:
      1. @instantdb/core
      2. @instantdb/react
      3. @instantdb/react-native
      4. @instantdb/admin
      5. instant-cli.
  3. sandbox/
    1. We built a few example apps, to make it easy to develop against the local version of packages.

Development

To kick everything off:

cd client
corepack enable # enables pnpm
pnpm i
make dev

With that, all frontend code should be up and running!

Dashboard & Docs

Visit localhost:3000, and you'll see Instant's homepage. You can make changes to the marketing pages, dashboard, or docs here.

If you press cmd + shift + 9, you'll also see a devtool window pop up. This can be useful if you want to enable feature flags.

Connect to a local backend

Right now all backend requests will go to api.instantdb.com. If you want to develop against your local backend, load localhost:3000, and set the devBackend flag:

localStorage.setItem("devBackend", true);

Now all requests will go to your local backend at localhost:8888. If you haven't set up a local backend, follow the server README

Running a local app

You can create local apps by following these steps

  1. On localhost:3000, click "Sign up" in the upper right corner.
  2. Enter your email address (or a fake one; it won't send a real email).
  3. Click "Send Code".
  4. Go back to the terminal window running the backend server. Look for a log entry showing an email. It will not have been sent, but you can read the HTML code of the email to find a 6-digit number.
  5. Use this number to complete the login on the website.
  6. You should now be in the dashboard with a newly created local app id.

You can then connect to this app in a new project with the following snippet

const APP_ID = '<your app id from your own server>'
const db = init({
  appId: APP_ID,
  apiURI: "http://localhost:8888",
  websocketURI: "ws://localhost:8888/runtime/session",
});

Packages and sandbox

All client SDKs live in packages/.

To develop against them, we've created a few sandbox examples. These examples let you locally test changes to the client SDK. We recommend you create an app in your dev environment and use it in each directories .env file

Based on what you change, you'll play with different examples:

  1. @instantdb/core ➡ sandbox/vanilla-js-vite/
  2. @instantdb/react ➡ sandbox/react-nextjs/
  3. @instantdb/react-native ➡sandbox/react-native-expo/
  4. @instantdb/admin ➡ sandbox/admin-sdk-express

Check out the sandbox READMEs to see how to run them.
