Autoload Config for PostHTML

Install

npm i -D posthtml-load-config

Usage

npm i -S|-D posthtml-plugin posthtml-plugin ...

Install plugins and save them to your package.json

package.json

Create a posthtml section in package.json.

Root
  |– client
  |– public
  |
  |- package.json

{
  "posthtml": {
    "parser": "posthtml-sugarml",
    "from": "/path/to/src/file.sml",
    "to": "/path/to/dest/file.html",
    "plugins": {
      "posthtml-plugin": {}
    }
  }
}

.posthtmlrc

Create a .posthtmlrc file.

Root
  |– client
  |– public
  |
  |-.posthtmlrc
  |- package.json

{
  "parser": "posthtml-sugarml",
  "from": "/path/to/src/file.sml",
  "to": "/path/to/dest/file.html",
  "plugins": {
    "posthtml-plugin": {}
  }
}

posthtml.config.js

Create a posthtml.config.js file.

Root
  |– client
  |– public
  |
  |- posthtml.config.js
  |- package.json

module.exports = (ctx) => {
  return {
    parser: ctx.ext === '.sml' ? 'posthtml-sugarml' : false,
    from: ctx.from,
    to: ctx.to,
    plugins: {
      'posthtml-plugin': ctx.plugin
    }
  }
}

Plugins can be loaded either using an {Object} or an {Array} in config.plugins.

{Object}

module.exports = (ctx) => {
  return {
    ...options,
    plugins: {
      'posthtml-plugin': ctx.plugin
    }
  }
}

{Array}

module.exports = (ctx) => {
  return {
    ...options,
    plugins: [
      require('posthtml-plugin')(ctx.plugin)
    ]
  }
}

⚠️ When using an Array, make sure to require() them.

Options

parser:

parser: 'posthtml-sugarml'

from:

from: 'path/to/src/file.sml'

to:

to: 'path/to/dest/file.html'

render:

Plugins

Options

{} || null: Plugin loads with defaults.

'posthtml-plugin': {} || null

⚠️ {} must be an empty object

[Object]: Plugin loads with given options.

'posthtml-plugin': { option: '', option: '' }

false: Plugin will not be loaded.

Order

Plugin order is determined by declaration in the plugins section.

{
  plugins: {
    'posthtml-plugin': {}, // plugins[0]
    'posthtml-plugin': {}, // plugins[1]
    'posthtml-plugin': {}  // plugins[2]
  }
}

Context

When using a function (posthtml.config.js), it is possible to pass context to posthtml-load-config, which will be evaluated while loading your config. By default ctx.env (process.env.NODE_ENV) and ctx.cwd (process.cwd()) are available.

Examples

posthtml.config.js

module.exports = (ctx) => ({
  parser: ctx.ext === '.sml' ? 'posthtml-sugarml' : false,
  from: ctx.from,
  to: ctx.to,
  plugins: {
    posthtml-include: {},
    posthtml-expressions: { locals: ctx.locals },
    htmlnano: ctx.env === 'production' ? {} : false
  }
})

"scripts": {
  "build": "NODE_ENV=production node posthtml",
  "start": "NODE_ENV=development node posthtml"
}
import { readFileSync } = require('fs')

const posthtml = require('posthtml')
const posthtmlrc = require('posthtml-load-config')

const sml = readFileSync('index.sml', 'utf8')

const ctx = { ext: '.sml' }

posthtmlrc(ctx).then(({ plugins, options }) => {
  posthtml(plugins)
    .process(sml, options)
    .then((result) => console.log(result.html))
})

package.json

"scripts": {
  "build": "NODE_ENV=production gulp",
  "start": "NODE_ENV=development gulp"
}

gulpfile.js

import { task, src, dest } from 'gulp'
import plugins from 'gulp-load-plugins'

task('pug', () => {
  const ctx = { locals: {} }

  return src('src/*.pug')
    .pipe(posthtml(ctx))
    .pipe(rename({ ext: '.html' }))
    .pipe(dest('dest'))
})

task('sml', () => {
  return src('src/*.sml')
    .pipe(posthtml())
    .pipe(rename({ ext: '.html' }))
    .pipe(dest('dest'))
})

task('html', () => {
  return src('src/*.html')
    .pipe(posthtml())
    .pipe(dest('dest'))
})

npm i -D html-loader posthtml-loader

package.json

"scripts": {
  "build": "NODE_ENV=production webpack",
  "start": "NODE_ENV=development webpack-dev-server"
}

webpack.config.js

module.exports = (env) => {
  module: {
    rules: [
      {
        test: /\.html$/
        use: [
          'html-loader',
          'posthtml-loader'
        ]
      }
    ]
  }
