@quatico/magellan-cli v0.7.1

@quatico/magellan-cli

This is the command-line interface (CLI) for the magellan project. You can run various commands to control the compiler and the server with it.

Getting started

Install CLI

Add a development dependency to your project, e.g., using yarn:

yarn add -D @quatico/magellan-cli

Add a build or watch target to your package.json:

// package.json
...
"scripts": {
    "build": "magellan compile ./src/functions",
    "watch": "magellan compile --watch ./src/functions",
    "serve": "magellan serve ./lib",
    ...
},

The compiler searches for annotated ES6 functions in the target folder, e.g,. ./src/functions and replaces them with server proxy-functions. All remaining code will be compiled with the default tsc using your tsconfig.json.

Do the following to move the invocation of your code to the server:

1. Extract some code from your client into a separate function
2. Move the function into an ES6 module, export the function and call it from the client
3. Add a comment with an @service annotation to the function, e.g., // @service()
4. Move the new ES6 module file into the dedicated folder, e.g., ./src/functions

5. Call the compiler, e.g., magellan compile ./src/functions. This will output

   1. The client results should go into the TS outDir, e.g.

   {
       {
       "compilerOptions": {
           "outDir": "./lib",
           ...
       },
   }

   1. the server functions into ./server-esm

6. Bundle the output with your html and stylesheets, for example into ./public

7. Serve your static page and functions with magellan serve ./public
8. Access the running page under http://localhost:3000.

Working with Webpack

Magellan provides a webpack loader - plugin combination that acts as a first step providing output for ts-loader and babel in case you work with a ES2015 target you wish to emit bundle to ES5.

The integration in your webpack configuration is straight forward:

Installation

yarn add -D @quatico/websmith-webpack

Update webpack.config.js

const { MagellanPlugin } = require("@quatico/websmith-webpack");

module.exports = () => {
    return {
        // ...
        module: {
            rules: [
                //...
                // Add loader or replace ts-loader config if used
                {
                    test: /\.[jt]sx?$/,
                    include: [path.resolve(__dirname, "src")],
                    loader: MagellanPlugin.loader,
                },
                // ...
            ],
        },

        // ...

        plugins: [
            new MagellanPlugin({
                project: path.resolve(__dirname, "tsconfig.json"),
                serverModuleDir: path.resolve(__dirname, "server-esm"),
                functionsDir: path.resolve(__dirname, "src/functions"),
            }),
            // ...
        ],
    };
};

Configuration

The compiler provides various parameters for configuration. Display the help screen for more details:

magellan --help
magellan compile --help
magellan serve --help

For example, a custom configuration could look as follows:

magellan compile --project ./tsconfig.json --hostname http://dockerhost --port 8080 --debug
--watch ./src/functions

magellan serve ./lib --serverModuleDir ./server-esm
