@gramforge/images-wasm

The JSR-publishable, Deno/browser-portable Gramforge image renderer.

It re-exports the node-free surface of @gramforge/images (its ./wasm entry): the six card tree builders (buildStatusTree, buildFleetOverviewTree, …), the zod schemas, the ECharts→SVG chart projection, the Takumi WASM backend, the resvg-wasm rasterizer, and renderCardWasm.

No node: builtin, no sharp, no native napi — the wasm module bytes and font buffers are injected by the caller. That is exactly what lets it run:

• in Deno and on the edge (JSR-published, slow-types clean), and
• client-side in a browser — the Gramforge showcase Image Lab renders cards in-page from this package, no server round-trip.

On Node, prefer @gramforge/images directly for the native Takumi (napi) + sharp fast paths; this package is the portable sibling that shares the same tree builders and schemas.

Usage

import { buildStatusTree, renderCardWasm, STATUS_DIMENSIONS } from "@gramforge/images-wasm";

// `wasm` = the @takumi-rs/wasm module bytes; `fonts` = font buffers you fetched.
const tree = buildStatusTree({
  template: "status",
  agentName: "ci-runner",
  level: "ok",
  headline: "build passed",
  detail: { kind: "text", value: "42 tests green" },
  timestampIso: new Date().toISOString()
});

const png = await renderCardWasm(tree, STATUS_DIMENSIONS, { wasm, fonts });
