@metabase/custom-viz-thumbs

A simple custom visualization for Metabase. Renders thumbs up or down depending on whether the value meets the threshold.

Requires Metabase >= 64 (built with @metabase/custom-viz 2.0).

The query must return a single numerical value (1 row and 1 column).

npm install
npm run dev         # watch build + preview
npm run build       # compiles src/ → dist/, then packages it into a .tgz

npm run build writes <name>-<version>.tgz to the project root. Upload that file in Admin → Custom visualizations → Add to register the plugin.

Packaging is done by the metabase-custom-viz pack command from the SDK. The archive contains metabase-plugin.json (with the SDK version stamped in as sdk.version) plus the build output (dist/index.js and any whitelisted dist/assets/*).

npm run prettier    # format
npm run type-check  # tsc --noEmit
