Question

Automatically bundle and release an NPM package using the libnpm library

My goal is to automate publishing to NPM within my CI/build system. I came across libnpmpublish, which appears to be the right tool for the job. However, it clearly states that it does not package code into a tarball, even though the publish API requires a tarball input instead of a folder or path.

The suggested workaround is:

Since libnpmpublish doesn't create tarballs on its own, one solution is to generate your own tarball for publishing by running npm pack in the desired directory. You can then use
fs.createReadStream('my-proj-1.0.0.tgz')
and provide that along with require('./package.json') to libnpmpublish.

I'm wondering if there's a way to script this process programmatically in Node. I searched through NPM repositories but couldn't find a dedicated packaging tool. Although I did come across this code that seems to handle packing, it's part of an archived repository and not under libnpm.

After thorough research, the most suitable solution appears to be located at this npm-packlist repository. This tool generates a file list from a specified folder which can then be used with NPM's tar package, as illustrated in the accompanying README for npm-packlist.

Here's a clever workaround that involves utilizing the command line to achieve a similar functionality. In this scenario, I am generating and uploading a package via a REST command. By encapsulating the process in a promise that returns a stream, I can seamlessly integrate it into the formPost data:

const exec = require('child_process').exec;
return new Promise((resolve, reject) => {
    exec(`npm pack ${t}`, { cwd: d }, (error, stdout, stderr) => {
        if (error) {
            console.error(error);
            reject(error);
        }
        var f = d + p.sep + stdout.trim();
        if (debug) console.log(`zip file "${f}" created.`);
        resolve(fs.createReadStream(f))
    });
});

Feel free to give it a try!

Introducing libnpmpack, a tool that generates a tarball buffer in the precise format required by libnpmpublish. With this, the process can be simplified as follows:

const pack = require('libnpmpack')
const { publish } = require('libnpmpublish')

async function packageAndDeploy(packagePath) {
  // readPackageJson implementation not shown here
  const manifest = readPackageJson(packagePath)

  const tarball = await pack(packagePath)
  return publish(manifest, tarball)
}
