The library is a second brain with a grid
A personal UI library is where the patterns you have shipped — the ones that worked, the ones you rescued, the ones you swore never to repeat — live in reusable form. It is a second brain, but better organised: every entry has a job, a code shape and a note on when it earned its place. Frameworks give you a hundred components and zero memory of why yours are yours; a personal library is the opposite — small, opinionated, and full of scar tissue.
- Collect by job, not by novelty: the library holds patterns with a named function (settle an entrance, confirm a delete, show progress) — a component without a job sentence is decoration with storage.
- Steal shamelessly, credit always: half of any good library is patterns seen elsewhere and remade better — the note field records where the idea came from, because provenance is how taste compounds.
- Document the scar: each entry carries its failure history — 'v1 had no focus ring, v2 added it after a keyboard audit' — the scar is the teaching, and it is what makes the entry yours.
- Keep it shippable: a personal library earns its keep only if entries are copy-pasteable in under a minute — every entry ships as code plus tokens plus the one-line 'when to use'.
The Motif lesson: document in public
Motif's own library works because every entry is a page — code, notes, run logs, fidelity scores — and those pages are the site. The lesson transfers: a personal library that documents in public (a portfolio, a blog, a small site) stops being a private folder and becomes a reputation. The act of writing the 'when to use' note is where the learning actually happens; the folder was just the excuse.
# Pattern: confirm-before-destructive
Job let the user take back a misclick
Code [link/code block]
When destructive actions only; never for routine submits
Scars v1 used a modal -> interrupted everyone
v2 used inline 'Delete? / Confirm' -> better
v3 added Undo toast for the reversible cases
