@cho0o0/yaml-merge v4.1.0

yaml-merge

A super simple tool for merging YAML files into one file. (Forked from alexlafroscia/yaml-merge mainly for self usage. The license stays as MIT)

Installation

For the command line

npm install -g @cho0o0/yaml-merge

For use through Node

npm install --save @cho0o0/yaml-merge

Usage

yaml-merge takes a series of yaml files and merges them from left to right. This means that the first file will be overwritten by properties of the second, which is overwritten by properties of the third, etc.

Command Line

When using this tool from the command line, the output file will simply be written to the first arg.

yaml-merge output.yml test/fixtures/basic/a.yml test/fixtures/basic/b.yml

The provided file names will be resolved relative to the current directory. So, you an provide a relative path to the files, or an absolute path -- either method works just fine.

As a Node package

yaml-merge also provides a node package that can be consumed to get the output file programmatically.

const resolve = require('path').resolve;
const merge = require('@alexlafroscia/yaml-merge');

const output = merge(resolve('relative/path/to/file.yml'), '/Users/you/some/other/file.yml');
console.log(output); // Prints out the resulting YAML as a string
