esbuild-plugin-purescript

Purescript esbuild plugin

Esbuild integration for purescript

What this plugin does:

• Allows you to import .purs file directly from within your javascript.

What this plugin doesn not do:

• Run spago build or similar commands for you: this will only point esbuild to your existing output directory
• Tree shake using zephyr for you. If you want to use zephyr, checkout this example

Usage

First, install the library from npm:

npm install esbuild-plugin-purescript

Example build.js:

const esbuild = require("esbuild");
const PurescriptPlugin = require("esbuild-plugin-purescript");
const path = require("path");

esbuild
  .build({
    entryPoints: ["src/index.js"],
    bundle: true,
    outdir: "dist",
    plugins: [
      PurescriptPlugin({
        output: path.resolve(
          __dirname,
          "myOutput"
        ) /* set to 'output' by default */,
        sources: [
          "some/**/glob/*.purs",
        ] /* set to `spago sources` by default */,
      }),
    ],
  })
  .catch((_e) => process.exit(1));

Example src/index.js:

import { main } from "./Main.purs";

console.log("Loaded purescript code 🚀");

main();
