fly-execa v1.0.0

fly-execa

Execute shell commands with Fly

Install

npm install --save-dev fly-execa

API

fly-execa uses execa as its child_process wrapper. This means it has the same options as child_process.exec and shares execa's additional options.

.execa(command, options)

command

Type: string Any occurrences of $file will be replaced with the the relevant filepath or glob pattern.

options

Type: object See child_process.exec and execa for more info.

options.glob

Type: boolean If the command should use the glob pattern within source(), you must set this to true or 1. See here for example.

Usage

Iterate Once Per File

You can apply a command to each file of your glob match.

Instances of $file will be replaced by the file's path.

exports.default = function * () {
  yield this.source('src/*.js')
    .execa('cat $file')
    //=> fly-execa: console.log('this is src/a.js')
    //=> fly-execa: console.log('this is src/b.js')
    //=> fly-execa: console.log('this is src/c.js')
    .dist('dist');
}

Iterate Once Per Glob

You can use the current glob within your shell command.

Note: Currently, only one glob pattern is supported.

Instances of $file will be replaced by the glob:

exports.default = function * () {
  yield this.source('src/*.js')
    .execa('cat $file', {glob: true})
    //=> fly-execa: 
    //=>     console.log('this is src/a.js')
    //=>     console.log('this is src/b.js')
    //=>     console.log('this is src/c.js')
    .dist('dist');
}

Passing Arguments

Of course, command arguments may be passed within your command string.

exports.default = function * () {
  yield this.source('src')
    .execa('ls -alh $file', {glob: true})
    .dist('dist');
}
