lini-wasm

Lini compiles plain text to clean, themeable SVG — one small language for flowcharts, mindmaps, org charts, tables, ER schemas, sequences, charts, engineering drawings, floor plans, and circuit schematics.

This package is the compiler itself, as a WebAssembly module: the same engine as the lini binary, byte for byte, with no network calls and nothing to stand up beside it.

npm install lini-wasm

Node, Bun, Deno

The module is read off disk as it loads, so there is nothing to await.

import { compile } from "lini-wasm";

const svg = compile(`
{ direction: row; gap: 40; }
|box#write| "write"
|box#compile| "compile"
|box#svg| "SVG"
write -> compile -> svg
`);

Browsers and bundlers

Vite, Astro, webpack, or a plain <script type="module"> — the WebAssembly is fetched on first use, so init() is awaited once:

import init, { compile } from "lini-wasm";

await init();
document.querySelector("#figure").innerHTML = compile('|box| "hello"');

Bundlers pick this build up automatically. A page loading the file directly imports lini-wasm/web and passes the module's URL:

import init, { compile } from "https://esm.sh/lini-wasm/web";
await init("https://esm.sh/lini-wasm/lini_wasm_bg.wasm");

What it exports

| | | |---|---| | compile(src) | SVG — the default output, live var() colours and real <text> | | compile_html(src) | a self-contained HTML page around that SVG | | compile_static(src) | SVG with variables inlined and text outlined, for a rasteriser | | diagnostics(src) | every error and warning as JSON — codes, spans, fixes. Never throws | | desugar(src) | the source with all sugar lowered to primitives | | format(src) | canonical formatting, what lini fmt writes | | highlight(src) | the source as <span class="lini-tok-…"> HTML | | highlight_css() | the palette those spans wear, ready to ship beside them | | version() | the engine's version |

Everything but diagnostics, highlight and highlight_css throws on an error-level diagnostic, with the compiler's own play.lini:3:5: error: … message as the thrown value. TypeScript declarations ship with both builds.
