yml-in-place

Currently only supports adding a value to a block sequence. But includes utilities to fairly easily also add other features like setting or removing values from maps or sequences.

Usage

const addToSequence = require('yml-in-place').addToSequence

const yml = `
 language: node_js
 branches:
   only:
     - master
`

const newYml = addToSequence(yml, ['branches', 'only'], 'greenkeeper')
console.log(newYml)
// language: node_js
// branches:
//   only:
//     - master
//     - greenkeeper
