Context API

Let's explore the inside of the Weex Toolkit “Context API”.

module.exports = {
  name: 'dostuff',
  alias: 'd',
  run: async (context) => {
    // great! now what?
  },
}

Here‘s what’s available inside the context object you see all over Gluegun.

name	provides the...	3rd party
meta	information about the currently running CLI
config	configuration options from the app or plugin
fs	ability to copy, move & delete files & directories	fs-jetpack
http	ability to talk to the web	apisauce
parameters	command line arguments and options	yargs-parser
patching	manipulating file contents easily	fs-jetpack
print	tools to print output to the command line	colors, ora
inquirer	tools to acquire extra command line user input	inquirer
semver	utilities for working with semantic versioning	semver
strings	some string helpers like case conversion, etc.	lodash & ramda
system	ability to execute	node-which, execa, cross-spawn
open	ability to open files	open, chrome-opn

The context has “drawers” full of useful tools for building CLIs. For example, the context.meta.version function can be invoked like this:

module.exports = {
  name: 'dostuff',
  alias: 'd',
  run: async (context) => {
    // use them like this...
    context.logger.info(context.meta.version())

    // or destructure!
    const {
      logger: { info },
      meta: { version },
    } = toolbox
    info(version())
  },
}
