How To Access Dev Tool On Mobile Browsers

Recently, I was working on a side project with some friends. Unfortunately my PC had been damaged during the covid-19 pandemic and I couldn't get to fix it because of the lock-down, so I had to resort to coding on my mobile phone 🤦🏾‍♂️.

Somehow, my code works perfectly offline, but for some reasons, it did not go well online 🤒
And of course I'll be needing dev tool to access the console and check for errors.

Some minutes of googling later, I discovered it's very much possible to access the dev tool on mobile browsers with Eruda 🎉

Below is how you can do open the dev tool on chrome mobile browser

Step 0

Bookmark your current page by clicking the star ⭐ symbol from the chrome menu.

After doing this, you should see a toast message Bookmarked with an edit button:

Click the edit option and change the bookmark details to the following:

Name:

Mobile Dev Tool

URL (copy and paste code below):

javascript:(function () {var script=document.createElement('script');script.src="//cdn.jsdelivr.net/npm/eruda";document.body.appendChild(script); script.onload = function () { eruda.init() } })();

Step 1

• Visit the web page you want to inspect
• Enter the keyword Mobile Dev Tool into the search bar(you should see the page we bookmarked before with the url starting with javascript:...) click on the URL

• Wait for 3 Seconds for the Eruda icon to appear like below

• Click on the icon to open your dev tool

• Enjoy! 🎉

You need to share how you did all your coding on the phone! I think that's the bigger achievement here 😂

Lol 😅 I'll probably write an article about that too 🤹

This is so cool, Asaolu! Thanks for making this extremely cool tool. I'm really new to everything code and programming so hopefully this question might help other beginners like me and not be very trivial, but is there a way to edit the source code (not the element alone, which I noticed it is possible) of the inspected pages and then also save the html locally?

In the latest version of Chrome for Android, it is not possible to edit the bookmark or the bookmark URL

Awesome ❤️

The logo used to appear, but I can't get it to appear anymore. I used the bookmark, and I also made sure that chrome didn't omit the "JavaScript" part, to no avail. Why is it no longer working?

[Joydeep Bhowmik]

Same for me
