esbuild for Gleam that works on Erlang & JavaScript.

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

(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.bundle
}

See esgleam for all config options and their default values.

5. Run your build script

gleam run -m build

Install esbuild.

gleam run -m esgleam/install

Bundle the project into a library with src/{project_name}.gleam as your entry point and ./dist/{project_name}.js as your output file.

gleam run -m esgleam/bundle

Bundle the project into a single file to run with src/{project_name}.gleam as your entry point and ./dist/{project_name}.js as your output file. Similar to just running gleam run.

gleam run -m esgleam/app

Starts a dev server, serving the dist directory as /.

gleam run -m esgleam/serve

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.
