Write a Chrome App for your Website

This is easy. Download the sample file to your desktop, extract the archive and open the included manifest.json file in Notepad or any other text editor. You need to make a few changes to the file.

Add your website name in Line #2, put a short description of the website in line #3 (it should be less than 132 characters) and then replace in lines #5 & #7 with your own website URL. Please make sure that you are the owner of these websites and that you have verified their ownership using Google Webmaster Tools.

    "name": "Your website name",
    "description": "Your website description in 132 characters or less.",
    "app": {
        "urls": [""],
        "launch": {
            "web_url": ""
    "manifest_version": 2,
    "update_url": "",
    "version": "0.1",
    "icons": {
        "128": "icon.png"

Save the manifest.json file. Next create a 128×128 image with your website logo (you can use MS Paint for that) and save the file as icon.png in the same folder where the manifest.json file is saved. To save time, you may use the sample 128×128 image included with zipped archive.

Publish your Web App to the Chrome Store Our first Chrome app is now ready and we just need to push it to the Chrome store. Create a new zip file with the icon.png and manifest.json files.

Then go to the Chrome Dashboard and upload your zip file. On the next screen, choose a category for your app (I picked News => Blogs), add a detailed description (will help in SEO), some screenshots, pick a default language and publish your app. That’s it.

You do need to pay Google a one-time registration fee of $5 using Google Wallet to activate your developer account. This is optional if you are developing a Chrome app /extension for your local Chrome installation and do not wish to publish the app in the Chrome web store.

Create a Chrome Extension for your Website

Writing a basic Chrome extension for your website isn’t hard either.

Download the sample file and extract the contents. Change the manifest.json file to include your extension name and description. Then open the labnol.js file and include the URL of your RSS feed as explained in the following video tutorial.

Put all the files in a zip and upload it to your Chrome Dashboard. Add the appropriate meta data and, within minutes, your extension will be live in the Chrome store worldwide.
