new-component

Simple, customizable utility for adding new React components to your project.

Anyone else sick of writing the same component boilerplate, over and over?

This project is a globally-installable CLI for adding new React components. It's dead simple to use, and requires no configuration, although it's easy to customize it to fit your project's coding style.

Features

• Simple CLI interface for adding React components.
• Uses Prettier to stylistically match the existing project.
• Offers global config, which can be overridden on a project-by-project basis.
• Colourful terminal output!

Quickstart

Install via NPM:

# Using Yarn:
$ yarn global add new-component

# or, using NPM
$ npm i -g new-component

cd into your project's directory, and try creating a new component:

Your project will now have a new directory at src/components/Button. This directory has two files:

// `Button/index.js`
export { default } from './Button';

// `Button/Button.js`
import React, { Component } from 'react';

class Button extends Component {
  render() {
    return <div />;
  }
}

export default Button;

This structure might appear odd to you, with an index.js that points to a named file. I've found this to be an optimal way to set up components; the index.js allows you to import from the directory (eg. import Button from 'components/Button'), while having Button.js means that you're never lost in a sea of index.js files in your editor.

This structure is not currently configurable, but I'm happy to consider implementing alternatives!

Configuration

Configuration can be done through 3 different ways:

• Creating a global .new-component-config.json in your home directory (~/.new-component-config.json).
• Creating a local .new-component-config.json in your project's root directory.
• Command-line arguments.

The resulting values are merged, with command-line values overwriting local values, and local values overwriting global ones.

API Reference

Type

Control the type of component created:

• functional for a stateless functional component (default).
• class for a traditional Component class,
• pure-class for a PureComponent class,

Legacy createClass components are not supported.

Usage:

Command line: --type <value> or -t <value>

JSON config: { "type": <value> }

Template

Use a custom template.

The content of the template file will be copied to the component, with COMPONENT_NAME beeing replaced with the name of the component. An example template file:

type COMPONENT_NAMEProps = {};

const COMPONENT_NAME = (props: COMPONENT_NAMEProps) => {
  return <div />;
};

export default COMPONENT_NAME;

Usage:

Command line: --template <value> or -t <value>

JSON config: { "template": <value> }

Directory

Controls the desired directory for the created component. Defaults to src/components

Usage:

Command line: --dir <value> or -d <value>

JSON config: { "dir": <value> }

File Extension

Controls the file extension for the created components. Can be either js (default) or jsx.

Usage:

Command line: --extension <value> or -x <value>

JSON config: { "extension": <value> }

Prettier Config

Delegate settings to Prettier, so that your new component is formatted as you'd like. Defaults to Prettier defaults.

For a full list of options, see the Prettier docs.

Usage:

Command line: N/A (Prettier config is only controllable through JSON)

JSON config: { "prettierConfig": { "key": "value" } }

Example:

{
  "prettierConfig": {
    "singleQuote": true,
    "semi": false,
  }
}

(Ideally, the plugin would consume your project's prettier settings automatically! But I haven't built this yet. PRs welcome!)

Platform Support

This has only been tested in macOS. I think it'd work fine in linux, but I haven't tested it. Windows is a big question mark (would welcome contribution here!).

Development

To get started with development:

• Check out this git repo locally, you will need to ensure you have Yarn installed globally.
• In the folder run yarn install
• Check that command runs node ../new-component/src/index.js --help
• Alternatively you can set up a symlink override by running npm link then new-component --help. Note: this will override any globally installed version of this package.
