New features in v2

CSS Support

The new CLI supports css files within your extension by default. The default webpack bundler is configured with css-loader and style-loader. This means you can import a css file into your extension. Example:

// styles.css
.red {
  color: red;
}

import {initializeBlock} from '@airtable/blocks/ui';
import React from 'react';
import './styles.css'

function MyExtension() {
    return <div className="red">Hello world</div>;
}

initializeBlock(() => <MyExtension />);

Using code from other directories

The new CLI allows this method of code-sharing by allowing “sibling directories” outside the source directory to be bundled. Those other directories can include npm imports based on link or file.

More details and an example can be found here.

Customizing the webpack config

By default, the CLI uses webpack to bundle your code. Out of the box, it supports using plain JavaScript or TypeScript and styling via CSS files. If you want to customize the webpack config further, you can do so by installing the @airtable/blocks-webpack-bundler package. For more information about installing this package and customizing the webpack config, see the README for the @airtable/blocks-webpack-bundler package at packages/webpack-bundler/README.md.

Using a custom bundler

If customizing the webpack config as described above does not solve your use case, it is also possible to replace the bundler entirely with a custom implementation. This is will require a significant amount of work.

Custom bundlers allow users to replace the CLI's built-in bundling functionality that turns extension source code into publishable artifacts. Your custom bundler's output must conform to the Airtable platform's expected format, calling convention, and file structure.

Unlike other bundling systems, which allow configurability by composing multiple single-purpose plugins (or replacing just part of the bundling pipeline), this CLI exposes a simpler bundler extension API that expects a single, complete replacement of bundling functionality.

To use a custom bundler:

1. Save your bundler as a JavaScript file (i.e. index.js). The bundler must be a CommonJS module. If your bundler in written in TypeScript, you must use the transpiled version as the entry file.

2. Then, change the block.json ‘bundler.module’ option to point at your new bundler entry file; i.e.:

// block.json
{
    “bundler”: {
        “module”: “./bundler/index.js”
    }
}

1. Once the change is made, restart your dev server (if running on a dev server).

A bundler needs to implement the following APIs:

class Bundler {
    async bundleAsync(options: ReleaseBundleOptions): Promise<void> {
        // implement release build
    }

    async findDependenciesAsync(options: SubmitFindDependenciesOptions): Promise<{files: Array<string>}> {
        // used in `block submit`
    }

    async startDevServerAsync(options: RunDevServerOptions & RunDevServerMethods): Promise<void> {
        // implement run development build
    }

    async teardownAsync(): Promise<void> {
        // implement any work needed to gracefully
        // close bundler process
    }
}

export default function() {
    return new Bundler();
}

For more details about the bundler API, see src/bundler/bundler.ts

Static assets are still not supported by default, but you can now swap in your own bundler that supports this.
