Localizing your extension html pages in a snap!

Here is an astute method I got from Vitaly a colleague I worked with a few years ago for easily and quickly localizing your html files. It relies on jquery, the i18 chrome API and the corresponding dictionnary built in your extension package.

1/ Copy paste the following jquery code into a file you'll name translate.js

 $($=> {  
   $('[translate]').each((i, elem)=> {  
     let $elem = $(elem);  
     $elem.text(chrome.i18n.getMessage($elem.text()));  
   });  
 });


2/ edit each and every html page of your extension:
  • add a "translate" attribute to all elements requiring translation like:
  <span translate>theStringToTranslate</span>
  • include the above translate.js in your page.

Voila ... !

Extending an extension with a native app.

Usecase I've recently come across a specific requirement from a customer who wanted a chrome extension  fiddling with the user machine file system. To be more specific, the addon was supposed to allow for the download of a cloud-based compressed file, decompress it and place the result in a specific directory for consumption by another application. As many know, filesystem is sandboxed by chrome for security reasons and it is impossible per design to write files on the user machine outside of the control of the user. I ended-up with a specific architecture outsourcing of the unauthorized job to a native app which bears none of the constraints a chrome extension does. An elegant architecture NativeMessaging Chrome API allows an extension to control - ie launch,communicate with and close - an external application: Native application can be written in any language An instance of the native app is launched when the extension connects to a configured service Native app  recei

Intercepting file download in chrome

Here is a little JS snippet which prevents every file download  (and accessorily opens a new tab in Gsuite for attempts to download from the Gsuite):   chrome.downloads.onCreated.addListener(downloadItem => {       chrome.downloads.cancel( downloadItem.id, ()=>{         alert("DL canceled: "+downloadItem.finalUrl);         if (downloadItem.finalUrl.search("https://docs.google.com")!=-1){           var _driveUrl = downloadItem.finalUrl.replace(/export\?.*/,"");           chrome.tabs.create({url:_driveUrl}, ()=>{});         }       })   });

Filtering console messages in the chrome devtools window

Image
I was disappointed to see that the regexp '.*' filter button had disapeared starting from a given chrome version (I can't remember the exact one). In fact you still have this ability by entering a '/' surrounded expression in the filter field. As an example, if you want to remove all logs containing either badword1 or badword2 or badword3 : /^((?!badword1|badword2|badword3).)*$/ Try it!
