package.jsonのdependenciesをjsで書けたら面白いかなという試み

dependencies.js

const _deps = {}
const _devDeps = {}
function add(deps, devDeps) {
  Object.assign(_deps, (deps || {}))
  Object.assign(_devDeps, (devDeps || {}))
}
const devDeps = (targets) => add({}, targets)

add({
  "react": "^17.0.2",
  "react-dom": "^17.0.2",
  "react-scripts": "4.0.3",
}, {
  "@types/react": "^17.0.8",
  "@types/react-dom": "^17.0.5",
  "@testing-library/react": "^11.1.0",
})

devDeps({
  "eslint": "^7.31.0",
  "eslint-plugin-react": "^7.24.0",
  "typescript": "4.2.4",
})

;(() => {
  const packageJson = require('./_package.json')

  const dependencies = Object.assign(packageJson.dependencies, _deps)
  const devDependencies = Object.assign(packageJson.devDependencies, _devDeps)
  packageJson.dependencies = {}
  packageJson.devDependencies = {}

  Object.keys(dependencies).sort().forEach(key => {
    packageJson.dependencies[key] = dependencies[key]
  })
  Object.keys(devDependencies).sort().forEach(key => {
    packageJson.devDependencies[key] = devDependencies[key]
  })

  console.log(JSON.stringify(packageJson, null, 2))
})();

npm_install.sh

#!/bin/bash

mv package.json _package.json
node dependencies.js > package.json

npm install

mv -f _package.json package.json
