How to fetch every package name on npm using node.js (requires a lot of memory)

fetch.php

console.log("Grabbing list of all packages from npm...");
var request = require("sync-request");
const cliProgress = require("cli-progress");
var res = request("GET", "https://skimdb.npmjs.com/_all_docs");
const fs = require("fs");

var packages = JSON.parse(res.getBody("utf8")).rows;
var packagejson = {
  name: "all-packages-in-a-json-file",
  version: "1.0.0",
  description: "",
  main: "",
  scripts: {
    test: 'echo "Error: no test specified" && exit 1',
  },
  keywords: [],
  author: "",
  license: "CC0",
  dependencies: {},
};

console.log(
  `Done. ${packages.length} packages were successfully grabbed from npm.`
);
console.log("Generating a package.json of the packages from npm.");

// create new progress bar
const b1 = new cliProgress.SingleBar({
  format:
    "CLI Progress |" +
    _colors.cyan("{bar}") +
    "| {percentage}% || {value}/{total} Chunks || Speed: {speed}",
  barCompleteChar: "\u2588",
  barIncompleteChar: "\u2591",
  hideCursor: true,
});

b1.start(packages.length, 0, {
  speed: "N/A",
});

var i = 0;
while (i < packages.length) {
  var package = packages[i].id;
  packagejson.dependencies = Object.assign(packagejson.dependencies, {
    [package]: "*",
  });
  b1.increment();
  i++;
}
b1.stop();
console.log(`Done. Saving to ${process.argv[2] || "allpackages.json"}`);

fs.writeFileSync(
  process.argv[2] || "allpackages.json",
  JSON.stringify(packagejson)
);

I got 16 gigs, should I give it a try?

rewrite that in c++ but it uses the system function

sure why not

no, JSON.stringify hates large objects, so I'm rewriting it in c++
