Can I Add a Debug Script to Npm?
I Have Edited My Package. Json to Customize the "Start" Script So It Adds the --Debug Flag to Node: "Scripts": { "Start": "Node --Debug Server. Js" } Is There...
I have edited my package.json to customize the "start" script so it adds the --debug flag to node:
"scripts": {
"start": "node --debug server.js"
}
Is there a way of adding new scripts for example a debug script that would do what my customized "start" is doing right now?
I'm looking to be able to execute:
npm debug

In your package.json define the script
"scripts": {
"debug": "node --inspect server.js"
}
And then you can use npm's run-script
npm run-script debug
or the shorter version
npm run debug
From the nodejs docs:
The legacy debugger has been deprecated as of Node 7.7.0. Please use --inspect and Inspector instead.
So starting from Node 7.7.0v use --inspect
VS Code adds a debug button inline in the package.json file
Open
package.jsonand click debug abovescriptssectionSelect script to debug
Debugger should be attached
for remote debug get npm-cli.js path
> npm --verbose
npm info it worked if it ends with ok
npm verb cli [
npm verb cli 'C:\\Program Files\\nodejs\\node.exe',
npm verb cli 'C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js',
npm verb cli '--verbose'
npm verb cli ]
npm info using npm@6.14.14
npm info using node@v14.17.5
then
node --inspect-brk "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" run your-npm-script
for mac or linux
➜ ~ npm --verbose
npm info it worked if it ends with ok
npm verb cli [
npm verb cli '/usr/local/Cellar/node@14/14.18.2/bin/node',
npm verb cli '/usr/local/bin/npm',
npm verb cli '--verbose'
npm verb cli ]
npm info using npm@6.14.15
npm info using node@v14.18.2
node --inspect-brk "/usr/local/bin/npm" run your-npm-script
