Code Generation

There two main approches of handling upgrades when using a code generator:

1. The generated code is never touched (only extended...), and regeneration only updates these files
2. Generated code is stored in a separate branch where generation is done no changes are done manually, the generated branch is merged with master at each upgrade

I find the first approach hard to work with for two reasons:

1. some files can't be extended like package.json ...
2. Extending all the files makes for bigger code base and adding simple changes can add a lot of work

# LinkedIn scans your browser for 4,934 Chrome extensions. Here is how to see it yourself.

I was debugging an unrelated console error on linkedin.com last week and noticed something odd: hundreds of failed requests to `chrome-extension://invalid/`.

Here is what is going on.

Any web page can test whether you have a specific Chrome extension installed by requesting a file from it. If the extension is there, the file loads. If it is not, Chrome rewrites the URL to `chrome-extension://invalid/` and the request fails silently. No permission needed, nothing visible to the user.

LinkedIn's page bundle walks a hardcoded list of extension IDs and probes each one in turn. I logged the list. It contains 4,934 entries, in alphabetical order, each paired with a real file path inside that specific extension: `icon16.png`, `content.css`, `assets/index-DgZXh0UX.js`. Nobody writes those by hand. Someone crawled the Chrome Web Store, downloaded the extensions, parsed their manifests and built a detection list.
