Compare node_modules for each releases - compare

Question

Looking for a way to compare package changes between releases.
I need a script or something that when run will show the difference (what packages are new, deleted or updated) between master tagged releases, by comparing the node_modules.
List with all changed or new packages/modules within tree of node_modules.

just came back from holiday, so this is the way I attempted a solution:
const checker = require('license-checker')
const compareVersions = require('compare-versions')
const rimraf = require('rimraf')
const { WebClient } = require('#slack/web-api')
const { exec } = require('child_process')
// An access token (from your Slack app or custom integration - xoxp, xoxb)
const token =
'xoxp-3712510934-8544rv58640-699363584817-a66630cfebf2f81e59478c3f8u0e178b'
const channel = 'where_to_post_report'
let prevReleasePackets
let currReleasePackets
function comparerVersion(otherArray) {
return current =>
otherArray.filter(other => other.name === current.name).length === 0
}
function comparerVersionNo(otherArray) {
return current =>
otherArray.filter(
other =>
other.name === current.name &&
compareVersions(other.version, current.version) === -1
).length === 0
}
function mapToData(libs) {
return Object.keys(libs)
.filter(key => key.indexOf('sm-web') === -1 && key.indexOf('debug') === -1)
.map(key => {
const lib = libs[key]
const name = lib.name
.replace(/#/g, '_')
.replace(/\./g, '_')
.replace(/\//g, '_')
const version = lib.version.replace(/#/g, '_').replace(/\//g, '_')
return {
name,
version,
}
})
}
function groupBy(objectArray, property) {
return objectArray.reduce((acc, obj) => {
const key = obj[property]
if (!acc[key]) {
acc[key] = []
}
acc[key].push(obj.version)
return acc
}, {})
}
function getPackets(path) {
return new Promise((resolve, reject) => {
checker.init(
{
start: path,
production: true,
customFormat: {
name: '',
version: '',
},
},
(err, packages) => {
if (err) {
// Handle error
console.log(err)
reject(err)
} else {
// The sorted package data
const packagesReduced = groupBy(mapToData(packages), 'name')
const higerVerionList = []
Object.keys(packagesReduced).forEach(key => {
const versions = packagesReduced[key]
const descVersions = versions.sort(compareVersions).reverse()
higerVerionList.push({ name: key, version: descVersions[0] })
})
resolve(higerVerionList)
}
}
)
})
}
function clonePrevious(tag) {
return new Promise((resolve, reject) => {
exec(
`git clone https://bitbucket.path_to_repo.git prevVersion && cd prevVersion && git checkout tags/${tag} && yarn && cd ..`,
async (error, stdout, stderr) => {
if (error) {
console.warn(error)
reject(error)
}
if (stdout) {
const prevPacks = await getPackets('./prevVersion')
resolve(prevPacks)
} else {
resolve(stderr)
}
}
)
})
}
async function sendReportToSlack(report) {
const web = new WebClient(token)
const res = await web.chat.postMessage({
channel,
text: report,
})
// `res` contains information about the posted message
console.log('Report sent: ', res.ts)
}
const readline = require('readline').createInterface({
input: process.stdin,
output: process.stdout,
})
console.log('Deleting prevVersion folder')
rimraf('prevVersion', async () => {
console.log('Done deleting prevVersion folder')
readline.question(
`What's the version tag for previous release?`,
async tag => {
console.log(`Start cloning and shit the release ${tag}!`)
readline.close()
prevReleasePackets = await clonePrevious(tag)
currReleasePackets = await getPackets('./')
const update = currReleasePackets.filter(
comparerVersionNo(prevReleasePackets)
)
const deleted = prevReleasePackets.filter(
comparerVersion(currReleasePackets)
)
const newPacks = currReleasePackets.filter(
comparerVersion(prevReleasePackets)
)
const slackMessage =
`*Packages changes from ${tag}*:\n\n` +
`*--Updated--*: ${JSON.stringify(
update
)},\n\n *--Deleted--*: ${JSON.stringify(
deleted
)} \n\n *--New--*: ${JSON.stringify(newPacks)}`
await sendReportToSlack(slackMessage)
}
)
})
