termigrator-cli

a CLI tool (using yargs) for termigrator migration apps.

Installing

npm install --save termigrator termigrator-cli

Getting Started

• create a cli

// in ./lib/cli
import Cli from 'termigrator-cli'

import migrator from './path/to/migrator'
import pkg from '../package.json'

export default new Cli({
  version: pkg.version,
  migrator,
})

• create bin file in ./bin/your-app-name

#!/usr/local/env node

require('../dist/cli').start()

• update the file permissions to make it executable

chmod +x ./bin/your-app-name

• add npm bin entry to package.json

{
  "bin": "./bin/your-app-name"
}

Configuration

Both the CLI and migrator can be configured using the configure and createMigrator hooks.

import Cli from 'termigrator-cli'

import createMigrator from './path/to/migrator'
import pkg from '../package.json'

export default new Cli({
  version: pkg.version,

  // define a #configure method that receives the yargs instance
  configure(yargs) {
    return yargs.options({
      foo: {
        alias: 'f',
        describe: 'my custom global option',
        demand: true,
        global: true,
        default: 'bar'
      }
    })
  },

  // define a #createMigrator method (instead of passing in the migrator) that
  // receives the parsed argv instance from yargs and should return a valid
  // migrator or a promise that resolves to a valid migrator
  createMigrator(argv) {
    return createMigrator(argv.foo)
  }
})
