babel-plugin-react-pug

Chuck out JSX and use Pug!

Build Status Coverage Status dependencies Status Standard - JavaScript Style Guide NPM Downloads

A tiny, performant babel plugin that lets you use Pug over JSX, giving you a productive and readable alternative for defining React Component templates. In essence, the plugin transforms Pug templates into React function calls. Supports React Native!

This is not the official Pug plugin for converting Pug into JSX. Please see babel-plugin-transform-react-pug!

Example

In

class Profile extends React.Component {
    ...
    render() {
        return pug`
            #profile.profile__container
                h1.profile__name ${this.state.name}
        `
    }
}

Out

class Profile extends React.Component {
    ...
    render() {
        return React.createElement('div', { id: 'profile', className: 'profile__container' },
            React.createElement('h1', { className: 'profile__name' }, this.state.name));
    }
}

Installation

$ yarn add babel-plugin-react-pug --dev

Features

babel-plugin-react-pug supports Pug features that make the most sense when using Pug as a template language for React.

Attributes

Class

Using the pug class syntax will automatically rename the attribute to className - so you won't have to worry about this!

class Profile extends React.Component {
    ...
    render() {
        return pug`
            .profile__card
        `
    }
}

Other Attributes / Events

class Profile extends React.Component {
    ...
    render() {
        return pug`
            #profile__01.profile__card(title="Profile Title")
        `
    }
}

...or with interpolations:

class Profile extends React.Component {
    ...
    render() {
        return pug`
            #profile__01.profile__card(onClick=${ this.update })
        `
    }
}

Conditionals

class ProfileList extends React.Component {
    ...
    render() {
        return this.state.profiles.length
            ? pug`ul#profile__list Your list of profiles.`
            : pug`p.profile__error An error has occurred.`
    }
}

Loops

class ProfileList extends React.Component {
    ...
    render() {
        return pug`
            ul#profile__list ${ this.state.profiles.map((item) => pug`li ${item.name}`) }
        `
    }
}

Components

To include components you don't need to use interpolation, just ensure that the component name is capitalised. For example:

class Profile extends React.Component {
    ...
    render() {
        return pug`
            ProfileCard(cardImage=${ this.state.imgSrc })
        `
    }
}

Include

You can include pug templates into your components, for example say you have tpls/profile-footer.pug:

.profile__footer
    .profile__footer__img
        img(src="http://placehold.it/200x200")

...now you can include the file in the component:

class Profile extends React.Component {
    ...
    render() {
        return pug`
            .profile__container
                h1.profile__title ${ this.state.title }
                .profile__body
                    h2.profile__subtitle ${ this.state.subtitle }
                include ./tpls/profile-footer.pug
        `
    }
}

Extends

You can harness the awesome power of Pug's extends to have component template inheritance!

For example, you could specify a base component template (tpls/base-profile.pug):

.profile__container
    .profile__header
    block content
.profile__footer
    h3 This is the footer!
    block footer
    p This is the sub footer text!

...now reference this in the component:

class Profile extends React.Component {
    ...
    render() {
        return pug`
            extends ./tpls/base-profile.pug
            block content
                h2.profile__title ${ this.state.title }
            block footer
                ul.profile__links ${ this.state.links.map((link) => pug`li.link ${ link }`) } 
        `
    }
}

Block append / prepend

You can also use append and prepend blocks in your React components.

For example, if you have the following base component template (tpls/base-profile.pug):

.profile__container
    block content
        h1.profile__title Profile
.profile__footer
    h3 This is the footer!
    block footer
    p This is the sub footer text!

...now reference this in the component, with the added keyword append to the block:

class Profile extends React.Component {
    ...
    render() {
        return pug`
            extends ./tpls/base-profile.pug
            block append content
                h2.profile__name ${ this.state.name }
            block footer
                ul.profile__links ${ this.state.links.map((link) => pug`li.link ${ link }`) } 
        `
    }
}
