handlebars-entry-loader v1.2.1

Handlebars Entry Loader

Webpack loader to enable using Handlebars templates as entry points.

Similar to all of the other Handlebars loaders, but with 100% more TypeScript and goats!

Includes support for:

• Data
• Partials
• Helpers
• Decorators

Usage

const ExtractTextPlugin = require('extract-text-webpack-plugin');

const ExtractHandlebars = new ExtractTextPlugin({
    allChunks: false,
    filename: '[name].html'
});

module.exports = {
    entry: {
        'index': 'src/templates/homepage.hbs'
    },
    module: {
        loaders: [
            {
                test: /\.hbs$/,
                use: ExtractHandlebars.extract([
                    {
                        loader: 'html-loader',
                        options: {
                            minimize: false
                        }
                    },
                    {
                        loader: 'handlebars-entry-loader',
                        options: {
                            partials: 'src/partials/**/*.hbs',
                            helpers: 'src/helpers/**/*.helper.js',
                            data: 'src/data.json'
                        }
                    },
                ])
            },
        ]
    },
    plugins: [
        ExtractHandlebars
    ],
    output: {
        path: 'dist/'
    }
}

See src/examples for more complex configurations.

Options

Data

data: {}

Data to pass to the handlebars template.

Can either be a JavaScript Object {foo: 'bar'} or a path to a JSON file to load.

Partials

File glob to load Handlebars Partials from.

Defaults to null (won't load any partials)

Example:

config:

partials: 'src/partials/**/*.hbs'

src/partials/foo/bar.hbs:

<p>Hello {{name}}, I am foo/bar</p>

something.hbs:

{{> src/partials/foo/bar.hbs name="Something" }}

Partial namer

By default partials will use the file name minus extension as the partial name, this may be undesirable (e.g. multiple partials with the same name in different directories)

To override this behaviour, provide a partialNamer function:

partialNamer: function(partial) {
    return partial.replace('src/partials/', '').replace('.hbs', '');
}

something.hbs

{{> foo/bar }}

Helpers

File glob to load Handlebars Partials from.

Defaults to null (won't load any partials)

Example:

config:

helpers: 'src/helpers/**/*.helper.js'

src/helpers/json.helper.js:

exports.default = function(data) {
    return JSON.stringify(data, null, ' ');
};

something.hbs:

<pre>{{src/helpers/json.helper.js someJSObject}}</pre>

Helper namer

helperNamer: helper => helper

By default helpers will use the file name minus extension as the helper name, this may be undesirable (e.g. multiple helpers with the same name in different directories)

To override this behaviour, provide a helperNamer function:

helperNamer: function(helper) {
    return helper.replace('src/helpers/', '').replace('.js', '');
}

something.hbs

<pre>{{json someJSObject}}</pre>

Decorators

Decorators follow the same config rules as helpers, using the following options:

decorators: 'src/decorators/**/*.js',
helperNamer: function() {...}

Debug

Set to true to wrap Handlebars templates & partials with HTML comments containing debugging information (name, path, data, etc.)

Useful to enable based on NODE_ENV:

debug: process.env.NODE_ENV !== 'production'

Prevent JS output

By default we prevent Webpack from emitting a .js file with each Handlebars entry point.

If this is causing issues with other loaders, you can turn it off:

preventJsOutput: false
