esgleam

esbuild for Gleam that works on Erlang & JavaScript.

Quick start

1. Create a Gleam project as you would normally and make sure you have a file in src with the name of your project (as specified in gleam.toml)

2. Install esbuild

$ gleam run -m esgleam/install

$ gleam run -m esgleam/bundle

See /dist for your bundled code

4. To start a development server

$ gleam run -m esgleam/serve

Advanced Usage

(Follow steps 1-2)

3. Create /src/build.gleam with the following

import esgleam

pub fn main() {
  esgleam.new("./dist/static")
  |> esgleam.entry("main.gleam")
  |> esgleam.target("esnext")
  |> esgleam.target("firefox110")
  |> esgleam.bundle
}

5. Run your build script

$ gleam run -m build

Installation

If available on Hex this package can be added to your Gleam project:

gleam add esgleam

and its documentation can be found at https://hexdocs.pm/esgleam.

Roadmap

• Create file watcher for *.gleam which runs on both Erlang and JavaScript
• Fix bug with STDOUT/STDERR not being shown when running esbuild in the erlang target
• Write tests for config options
• Add more config options if needed
• Pseudo-SourceMaps until #1341 merges
• Consider creating a way to use plugins
• Hot Module Reloading?????
