I created a node script which checks if my project contains lock file or not. If it doesn't then I want to abort my npm build. Any idea how to do that?
lock-check.js
const path = require('path');
const fs = require("fs");
const lockFiles = ["package-lock.json", "npm-shrinkwrap.json", "yarn.lock"];
let exists = 0;
function checkIfExists()
lockFiles.forEach(
(lf) =>
if (fs.existsSync(lf))
exists++;

return exists > 0;

to abort you can doprocess.exit(1)with 1 or any non zero exit code to tell it was not completed successfully

I suspect that would work. npm is a different process so it will resume execution.

it works fine in webpack configs i have been using it for some custom tests before building it. just exit code should be non-zero

Yes you are right about Exit codes. If any step of the scripts exits with a non-zero exit code the whole process will terminate. See docs.npmjs.com/misc/scripts#exiting I just read that

To abort the build process you just have to call process.exit(1),
Here I have used 1 but you can use any non-zero exit code to tell it wasn't a successful build as 0 means successful.
