Usage

import { createCsv } from 'comparing-dependencies'

const csv = createCsv([
  {
    name: 'prj_01',
    dependencies: {
      react: '^17.0.2',
      dayjs: '^1.10.3',
    },
    devDependencies: {
      webpack: '^5.51.1',
    },
  },
  {
    name: 'prj_02',
    dependencies: {
      react: '^17.0.2',
      dayjs: '^1.10.2',

      moment: '^2.29.1',
      webpack: '^4.46.0',
    },
  },
])

console.log(csv)

Example codes

• Examples for comparing-dependencies

Replacing package.json files

Place the package.json files that you want to compare under the ./examples/inputs directory. Then, the name field in each package.json will be output as a column name in the CSV.

examples/inputs/
  |- example_package_01.json
  |- example_package_02.json
  |- example_package_03.json

These file names can be anything you want.

Running

$ yarn run-example

Checking the result

The result.csv will be output at the ./examples.

$ open ./examples/result.csv
