Grunt VTEX

A Grunt convention-over-configuration meta-project.

The file index.coffee exposes only one function: generateConfig.
It receives your grunt, pkg (your package.json parsed object) and options.
It returns an object with configurations for all tasks used across projects in VTEX.

Your project should only define very specific customizations outside of this config.
This enforces uniformity and eases advancing configurations across every project simultaneously.

Important - contributors

If you are heavily altering a defined task or adding a new one, please bump the minor version.

Usage

In your Gruntfile:

GruntVTEX = require 'grunt-vtex'

module.exports = (grunt) ->
  pkg = grunt.file.readJSON 'package.json'

  options = {...}
  config = GruntVTEX.generateConfig grunt, pkg, options

  ## customize by altering config
  config.copy.main = {...}
  
  tasks = {...}

  grunt.initConfig config
  grunt.loadNpmTasks name for name of pkg.devDependencies when name[0..5] is 'grunt-'
  grunt.registerTask taskName, taskArray for taskName, taskArray of tasks

Options

  • options.relativePath where to put files under build folder
  • options.replaceGlob which files to replace on copy:deploy task
  • options.replaceMap which keys to replace with which values on copy:deploy task
  • options.devReplaceGlob which files to replace on copy:dev task
  • options.devReplaceMap which keys to replace with which values on copy:dev task
  • options.copyIgnore array of globs to ignore on copy:main
  • options.dryrun if true, nothing will actually be deployed
  • options.open whether to open automatically a page on running
  • options.verbose whether to log all available information
  • options.port which port the connect proxy should listen to
  • options.replaceHost function to replace the host upon proxying
  • options.proxyTarget what target to proxy to
  • options.followHttps whether to follow HTTPS redirects transparently and return HTTP
  • options.livereload whether to use livereload, or in which port to use it
  • options.middlewares array of middlewares to use in connect
  • options.headers map with headers to be sent with the request
  • options.janusEnvHeader header required by Janus with the requested env. Defaults to X-VTEX-Janus-Router-CurrentApp-EnvironmentType

Grunt command line options

  • --stable: proxies to stable API's instead of beta.
  • --link: sibling project directories to link in order to develop locally.
  • --ft: features that should be toggled.

Registered tasks

  • getTags: this task fetches the current tags.json file, which tells us which apps are currently published with which versions.

Example excerpt of a tags.json file:

{
    oms-ui: {
        stable: {
            2: "2.9.76"
        },
        beta: {
            2: "2.9.99-beta"
        }
    },
    license-manager-ui: {
        stable: {
            2: "2.1.23"
        },
        beta: {
            2: "2.1.23"
        }
    },
    vtex-id-ui: {
        stable: {
            2: "2.2.6",
            3: "3.2.29"
        },
        next: { },
        beta: {
            2: "2.2.6",
            3: "3.2.29-beta"
        },
        alpha: { }
    }
}

Using link

To develop two projects simultaneously, follow these steps:

  • Clone the other project into a sibling directory, install and start with the "dev" task.

      $ cd Projects/
      $ git clone git@github.com:vtex/front.shipping-data.git
      $ cd front.shipping-data
      $ npm i
      $ grunt dev // some target which doesn't run a server and livereload
    
  • In another terminal tab, start grunt with the link option, passing the name of the component:

      $ cd Projects/vcs.checkout-ui
      $ grunt --link front.shipping-data
    

This will symlink the build folder from the sibling into the build folder in this project.

You can also separate multiple projects with a comma, e.g.

    $ grunt --link front.shipping-data,front.cart

Using feature toggles

You may turn a feature on using the ft option:

    $ grunt --ft totem

Advanced devReplaceMap usage

devReplaceMap accepts a string or a function as a value for a key. In case of a function, it will receive three parameters:

  • features, the map of toggled features (using --ft)
  • symlink, the symlink task config, which is created according to the --link option
  • tags, the tags.json map of published projects.

The result of this function is passed on to the replace function. Therefore, you can return a function that handles the pattern matching!

e.g.:

featureToggleReplace = (features, symlink, tags) ->	(match) ->
	if features?['totem'] then match else ''

linkReplace = (features, symlink, tags) -> (match, path, app, major) ->
	env = if grunt.option('stable') then 'stable' else 'beta'
	if symlink[app]
		console.log "link".blue, app, "->".blue, "local"
		return "/#{app}/#{path}"
	else
		version = tags[app][env][major]
		console.log "link".blue, app, "->".blue, version
		return "//io.vtex.com.br/#{app}/#{version}/#{path}"

devReplaceMap = {}
devReplaceMap["{{ 'checkout-custom.css' | legacy_file_url }}"] = '/arquivos/checkout-custom.css'
devReplaceMap["{{ 'checkout-custom.css' | file_url }}"] = '/files/checkout-custom.css'
devReplaceMap["{% if config.kiosk %}(\n|\rn|.)*\{% endif %}"] = featureToggleReplace
devReplaceMap["\\{\\{ \\'(.*)\\' \\| vtex_io: \\'(.*)\\', (\\d) \\}\\}"] = linkReplace
