@swc/plugin-relay

Setup

npm install --save-dev @swc/plugin-relay @swc/core

Example

The below shows how to configure @swc/plugin-relay and pass the options to Webpack:

Create an .swcrc.js file like the below:

// .swcrc.js

module.exports = {
  jsc: {
    experimental: {
      plugins: [
        [
          "@swc/plugin-relay",
          {
            rootDir: __dirname,
            artifactDirectory: "src/__generated__",
            language: "typescript",
            eagerEsModules: true,
          },
        ],
        // Or if you want to use multiple projects
        [
          "@swc/plugin-relay",
          {
            projects: [
              {
                rootDir: path.resolve(__dirname, '../project1'),
              },
              {
                rootDir: path.resolve(__dirname, '../project2'),
              }
            ],
            language: "typescript",
            eagerEsModules: true,
          },
        ],
      ],
    },
    parser: {
      syntax: "typescript",
      tsx: true,
    },
    transform: {
      react: {
        runtime: "automatic",
      },
    },
  },
};

And then update your swc-loader Webpack config:

const swcConfig = require("./.swcrc.js")

// ...

{
  include: path.resolve("./src"),
  test: /\.ts$/,
  use: [
    {
      loader: "swc-loader",
      options: swcConfig,
    },
  ],
}

Note: We're using a .swcrc.js file extension up above and importing the config directly because Relay needs access to __dirname, which can't be derived from the default JSON parsed from .swcrc.

Output import paths

By default, @swc/plugin-relay will transpile import paths based on the language option. You can use outputFileExtension to change the file extension of the generated import paths.

plugins: [
    [
        "@swc/plugin-relay",
        {
            rootDir: __dirname,
            artifactDirectory: "src/__generated__",
            language: "typescript",
            eagerEsModules: true,
            outputFileExtension: "js",
        },
    ],
],

In this example typescript graphql files will output transpiled import path of javascript ending with .js.
