Vue Tip: Force-Enable Vue Devtools in Production Build

Often we cannot reproduce a bug in the development environment and need to debug it in production.

Unfortunately, in most cases, the Vue Devtools browser extension is disabled in production builds:

Luckily, there is a way to force-enable it in production builds.

Open Console in Browser DevTools

First, we need to open the console in your browser's DevTools:

Windows or Linux: Ctrl + Shift + J

Mac: Cmd + Option + J

Access Vue App Instance

Now we need to get access to the Vue app instance:

If you are using Vue 2 you need to call:

For Vue 3, you need to run the following code in the console:

The app variable contains a reference to the Vue app instance:

We can now store the app version in a new variable called version:

Access Vue Devtools Instance

In the next step, we need access to the Vue Devtools instance which is available via window.__VUE_DEVTOOLS_GLOBAL_HOOK__:

We store it in a variable called devtools and set its property enabled to true:

Quote of the Week

JavaScript Tip: Clean up promises similarly to a try/catch/finally block

The finally() method of a Promise schedules a function, the callback function, to be called when the promise is settled (fullfilled or rejected).

It's very convienient for cleaning up similarly to try/catch/finally blocks.

Like then() and catch(), it immediately returns an equivalent Promise object, allowing you to chain calls to another promise method, an operation called composition.

This lets you avoid duplicating code in both the promise's then() and catch() handlers.
