If you're familiar with frontend Web -development, you could consider the Lustre CLI as something similar to -[vite](https://vitejs.dev) but built right into the framework! If you're not -familiar with what these tools are used for... then read on. - -The Lustre CLI is written in Gleam and requires **Erlang** to be installed even -if you are only building a JavaScript project. Most methods of installing Gleam -will guide you through installing Erlang too, but make sure you have it installed -before you try to use the Lustre CLI! - -Because the CLI is written in Gleam, you will run it using the `gleam` command. -As an example, starting a development server looks like this: - -```sh -gleam run -m lustre dev -``` - -<h2 id="lustre-add" class="member-name"> - <a href="#lustre-add">lustre add</a> -</h2> - -This command lets you install development-specific binaries and tools from outside -the Gleam ecosystem. Lustre tries to be smart about the executables it understands: -if you try to build a project without esbuild it will grab it, if it finds a -tailwind.config.js it will use tailwind, and so on. All binaries are added to -`build/.lustre/bin` in case you need to execute them manually. - -### `lustre add esbuild` - -[Esbuild](https://esbuild.github.io) is a bundler and build tool for JavaScript -projects. This is the backbone of a lot of Lustre's build tooling and will be -installed automatically if you use `lustre build` or `lustre dev`. - -Example: - -```sh -gleam run -m lustre add esbuild -``` - -### `lustre add tailwind` - -[Tailwind CSS](https://tailwindcss.com) is a utility-first CSS framework popular -among devs that want to quickly iterate on designs without touching CSS directly. -This will be installed automatically if Lustre detects a `tailwind.config.js` file -in your project. - -Example: - -```sh -gleam run -m lustre add tailwind -``` - -<h2 id="lustre-build" class="member-name"> - <a href="#lustre-build">lustre build</a> -</h2> - -Gleam projects can be compiled to JavaScript but this output is not always -desirable for frontend projects where many individual modules can cause HTTP -bottlenecks and slower load times. The `lustre build` command produces different -_bundles_ that are single JavaScript files containing all the code needed for an -application to run. - -If a `lustre build` subcommand is run without the necessary tooling installed, -Lustre will attempt to install it automatically. - -### `lustre build app` - -Bundle a Gleam application into a single JavaScript file. This requires a Gleam -module in your project with the same name as the project itself, and a public -`main` function that will be called when the application starts. - -_This can be any Gleam program_, but if your `main` function returns an -`App(Nil, model, msg)` then Lustre will automatically generate some boilerplate -to mount the app onto an element with the id `"app"` and start it. - -Flags: - -- `--minify` - Reduce the size of the output bundle by removing whitespace and - renaming variables. This is useful for production builds. - -Example: - -```sh -gleam run -m lustre build app -``` - -### `lustre build component` - -Lustre components are based on standard Web Components. This means they should -be usable outside of Lustre and Gleam! The `lustre build component` command takes -a module and bundles it into a single JavaScript file that can be included in -_any_ Web app to register a new Custom Element that can be used like native HTML -elements. - -For a module to be bundled as a component, it must adhere to the following rules: - -- There must be a `pub const name` that is a string representing the name of the - component to register. Remember that it must always contain a hyphen and follow - [these rules](https://developer.mozilla.org/en-US/docs/Web/API/CustomElementRegistry/define#valid_custom_element_names). - -- There must be a `pub fn` that has the type `fn() -> App(Nil, model, msg)`. It's - name is not important but in cases where multiple functions in a module fit this - type, the _first_ one will be used. - -Arguments: - -- `<module_path>` - The path to the Lustre component you want to bundle. This should - be in the same format that you would write to import the module in a Gleam file, - e.g. `ui/my_componnt` and **not** `src/ui/my_component.gleam`. - -Flags: - -- `--minify` - Reduce the size of the output bundle by removing whitespace and - renaming variables. This is useful for production builds. - -Example: - -```sh -gleam run -m lustre build component ui/counter -``` - -<h2 id="lustre-dev" class="member-name"> - <a href="#lustre-dev">lustre dev</a> -</h2> - -The `lustre dev` command starts a development server that builds and serves your -project. This lets you focus on development without having to worry about a backend -or additional tooling. - -Currently the server does _not_ watch for changes to your Gleam source files. You -must **restart the server** for changes to take effect. There have been discussions -about including a `watch` command in the Gleam compiler that would make this -possible. - -Flags: - -- `--port` - The port to serve the project on. Defaults to `1234`. - -- `--host` - The host to serve the project on. Defaults to `0.0.0.0` and is - accessible on localhosts and any other devices on the same network. - -- `--spa` - Serve the `index.html` file for all routes. This is useful for single - page applications where the frontend handles routing. - -- `--html` - Provide a custom HTML file to serve. This is useful if you want to - include your own styles or scripts. - - To make sure the Lustre bundle can be loaded, you must include the following - script tag somewhere in your HTML file: - - ```html - <script type="application/lustre"></script> - ``` - -- `--use-lustre-ui` - Include the stylesheet from - [lustre/ui](https://hexdocs.pm/lustre_ui/). This is mainly used in the example - projects, but you may use this option to quickly experiment with the library - yourself. - - If the `--html` flag is provided, this flag will be ignored. - -Example: - -```sh -gleam run -m lustre dev --port=8080 --use-lustre-ui -``` - -## Getting help - -The Lustre CLI is still an experimental work in progress. If you run in to issues -or have ideas for how it could be improved we'd love to hear from you, either by -[opening an issue](https://github.com/lustre-labs/lustre/issues) or reaching out -on the [Gleam Discord server](https://discord.gg/Fm8Pwmy). diff --git a/pages/reference/examples.md b/pages/reference/examples.md new file mode 100644 index 0000000..d6535a8 --- /dev/null +++ b/pages/reference/examples.md @@ -0,0 +1,49 @@ +# Lustre examples directory + +Each of the examples in this directory is a self-contained, complete Gleam app +that demonstrates a particular feature or concept of the library.
