3. Press F12 and click on the Console tab
4. Select the code below, copy it, paste it upon the Console line (The area next to the > character in the Console window), and press enter:

/*
the twitter api is stupid. it is stupid and bad and expensive. hence, this. 

Literally just paste this in the JS console on the bookmarks tab and the script will automatically scroll to the bottom of your bookmarks and keep a track of them as it goes. 

When finished, it downloads a JSON file containing the raw text content of every bookmark. 

for now it stores just the text inside the tweet itself, but if you're reading this why don't you go ahead and try to also store other information (author, tweetLink, pictures, everything). come on. do it. please?

A github workflow to track the progress of converting JavaScript to TypeScript.

Last year, we migrated a large project form JS to TS. We did this with ts-migrate, and we renamed all instances of any to $TSFixMe, to differentiate them from real uses of any.

Tracking the convertion over time

In order to see our progress on removing $TSFixMe, we build the a github workflow that adds comments to PRs with our progress, eg:

Remix Deferred

Remix Deferred is currently implemented on top of React's Suspense model but is not limited to React. This will be a quick dive into how "promise over the wire" is accomplished.

SSR + Hydration

It isn't rocket science, but a quick recap of how frameworks such as react do SSR:

1. Load data
2. Render the app
