Troubleshooting a .vue component in Chrome

Has anyone successfully debugged a .vue component in Chrome? I keep seeing orange markers for source code that Chrome doesn't recognize, making it difficult to inspect variables. Does anyone know how to accomplish this?

Answer №1

Absolutely, it is definitely possible.


First and foremost, ensure that you are utilizing a non-minified or non-production version of Vue.js. You can confirm this by checking the console output in your development tools. If your Vue version is a development version that allows for debugging, you should see a specific message in the console indicating so.

You are running Vue in development mode.
Make sure to turn on production mode when deploying for production.

Secondly, it is essential to install the Vue.js Devtools plugin.

Please note: if you are not using a web server and instead loading local files in the browser using "file://somefile.htm", you will need to access the Chrome extension settings and grant the plugin permission to access file URLs.


Thirdly, enable "source map." The process may vary depending on your setup. If your project is set up using CLI, locate your config/index.js file and ensure that the dev-tool property is set to devtool: 'source-map'.

For those using Webpack or Laravel mix, you can activate source maps with the .sourceMaps() method in the Webpack config file. Additional changes may be required as well. https://webpack.js.org/configuration/devtool/
