Geting started

1. Install module-butler within your project or globally or use it with npx directly.

yarn add -D module-butler

or

npm install -D module-butler

or

npx module-butler init

2. Set up module-butler by running:

module-butler init

or

npx module-butler init

3. Makes changes in .module-butler/config.js
4. Make changes to any template in .module-butler/templates/.
5. Add your GraphQL fragments in .module-butler/inpug.graphql. (See example)
6. Generate your modules by running:

module-butler generate

or

npx module-butler generate

Example

The following example used the templates that come out-of-the-box when running module-butler init.

Input

// .module-butler/input.graphql
Hello,
World

// Tip: add all your modules to generate all modules at the same time.

Outputs

modules/ is the default output directory. You can change it by changing outputDirectory in .module-butler/config.js.

// modules/Hello/index.js
console.log('module name:', 'Hello');

// modules/World/index.js
console.log('module name:', 'World');

Tips

Add a script in package.json

It is recommended to add a script in package.json, that runs module-butler generate and any other script, like prettier. For example:

{
  "scripts": {
    "module-butler": "module-butler generate && relay-compiler && prettier --write modules/"
  }
}

Then you can just run npm run module-butler or yarn module-butler.

Adding/removing/customizing templates

By default, running module-butler init, provides you with a default index.js template and you can change it any way you want. You can then, for example, create a utils.ts template for your utility functions. You can even change the file name of the template, like adding the module name, {{name}}, or changing the file extension to .ts instead of .js.

Templates

Templates in .module-butler/templates/ use handlebars as the templating language.

• Both the file name and file content are templatable, and have access to the same handlebars context.
• You can refer to .module-butler/templateAPI.ts for the full handlebars context.
• You can add or remove templates
• The handlebars file extension of templates (i.e. .hbs) is removed when generating your modules, but you are free to remove it from the template itself. The .hbs extension is only used for code editors, like VS Code, to recognize that its a handlebars file and give you syntax highlighting for that.
