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;

package.json

...

"scripts": 
 "prestart": "node ./lock-check.js" // Abort the task
 "start": "webpack-dev-server --config config/webpack.dev.js --hot --inline"


...

javascript node.js npm

  to abort you can do process.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.

You can read more on official nodejs docs
