npm package json editor that preserve newline and indentation
npm install package-json-editor> npm package editor that preserve newline and indentation
This is a mere wrapper around automerge so that we can use to edit npm package tree and preserve all the indentation, newline settings.
We can use this package to edit the tree directly using .set() method or we can edit the tree object directly and merge the new tree onto the old tree later with .merge().
``js
var packageJsonEditor = require('package-json-editor')
var originTree = fs.readFileSync('./package.json', 'utf-8')
var mutated = JSON.parse(originTree)
mutated.dependencies.debug = '^1.0.0'
mutated.description = 'new description'
delete mutated.license
var newTree = packageJsonEditor(originTree)
.merge(mutated)
.toString()
// or
var anotherTree = packageJsonEditor(originTree)
.set('dependencies.detect-indent', '^5.0.1')
.toJSON()
