feat(web): add Open VSX theme search by rynfar · Pull Request #6 · pylon-code/pylon

rynfar · 2026-08-11T22:39:34Z

Adds in-app search and import of editor themes from the Open VSX marketplace, on top of the existing local .vsix/VS Code theme import. ~2,700 insertions including a 776-line openVsxThemes.ts with 526 lines of tests.

Cherry-picked from upstream f0b57ca2313bd7971cefb366d3b3808152b014fc (pingdotgg/t3code#5654). Clean pick — it is built on the OKLCH palette work already merged, so it applies without conflict.

Worth a deliberate decision, not just a sync

This is the first thing in Pylon that reaches a third-party marketplace at runtime: it queries https://open-vsx.org/api/-/search and downloads extension archives to extract their theme JSON. That is a new network dependency and a new trust surface — Pylon previously only imported themes the user already had on disk.

Three new dependencies:jszip (unpack .vsix), jsonc-parser (theme JSON with comments), @noble/hashes (already in the catalog).

Flagging it plainly so the decision is explicit; the developer asked for it knowing the tradeoff.

Pylon-first checks

No visible "T3 Code"/"T3 Chat" copy introduced in the settings surface
Applies on top of the merged OKLCH palettes rather than fighting them

Verification

openVsxThemes, themePalette, vscodeThemeImport, themeBoot pass (85 tests)
Web typecheck, lint, format clean across 10 changed files
Confirmed jszip@3.10.1 and jsonc-parser@3.3.1 resolve after install

Not verified: no live marketplace search was performed against open-vsx.org, so the network path and archive extraction are covered only by the bundled tests.

Model: Claude Opus 5 (1M context). Harness: Claude Code.

Pylon-first checks

No visible "T3 Code"/"T3 Chat" copy introduced in the settings surface
Applies on top of the merged OKLCH palettes rather than fighting them

Verification

openVsxThemes, themePalette, vscodeThemeImport, themeBoot pass (85 tests)
Web typecheck, lint, format clean across 10 changed files
Confirmed jszip@3.10.1 and jsonc-parser@3.3.1 resolve after install

Not verified: no live marketplace search was performed against open-vsx.org, so the network path and archive extraction are covered only by the bundled tests.

Model: Claude Opus 5 (1M context). Harness: Claude Code.
