esbuild

This is the cross-platform WebAssembly binary for esbuild, a JavaScript bundler and minifier. See https://github.com/evanw/esbuild and the JavaScript API documentation for details.

Description

@spike-land-ai/esbuild-wasm provides the esbuild API backed by a WASM binary, enabling use in browsers and any environment that cannot run native esbuild binaries. It is a drop-in replacement for the official esbuild-wasm package, published under the @spike-land-ai scope to GitHub Packages.

Installation

npm install @spike-land-ai/esbuild-wasm

Note: This package is published to GitHub Packages. You must authenticate with the registry and set the scope in your .npmrc:

@spike-land-ai:registry=https://npm.pkg.github.com

Usage

Node.js

import * as esbuild from "@spike-land-ai/esbuild-wasm";

await esbuild.initialize({});

const result = await esbuild.transform("const x: number = 1", {
  loader: "ts",
});

console.log(result.code); // "const x = 1;\n"

Browser

import * as esbuild from "@spike-land-ai/esbuild-wasm/browser";

await esbuild.initialize({
  wasmURL: "/path/to/esbuild.wasm",
});

const result = await esbuild.transform("let x: number = 1", {
  loader: "ts",
});

console.log(result.code);

WASM Binary

The esbuild.wasm binary is auto-generated from the esbuild source at version 0.27.3. It is not compiled in this repository — it is vendored directly from the upstream esbuild release.

See WASM_CHECKSUMS.md for integrity verification instructions.
