Hot Module Loading

When loading modules with await import() in Node.js, they become permanently cached. The subsequent await import(url), given the same url will return the exact same module.

If one needs to pick up the changes made to file system, they need custom loader hooks.

For this purpose specifically, only resolve is sufficient (note how mtime is used for cache busting).

Warning! The old modules are never actually reclaimed from memory, so some additional considerations must be taken into account:

ESBuild + Watch + Reload in Node.js

Iterate on a module locally, and dynamically assemble it with ESBuild.

Especially useful with npm link but can also work on arbitrary entrypoints.

Realtime Collaborative Editing

This document describes both high level and more in-depth aspects of realtime collaborative editing. If you're busy, here's a TL;DR:

• users expect it
• we need it
• we can do it
• we can sustainably support it
• there are a number of problems to solve of various severity, all of them solvable
