Version 3 Changes
Converted this repository to a monorepo with the following packages:
- @hpcc-js/wasm-base91
- @hpcc-js/wasm-duckdb
- @hpcc-js/wasm-expat
- @hpcc-js/wasm-graphviz
- @hpcc-js/wasm-graphviz-cli
- @hpcc-js/wasm-zstd
- @hpcc-js/wasm (meta package for backward compatibility)
Quick Start
1import { Base91 } from "@hpcc-js/wasm-base91"; 2import { Graphviz } from "@hpcc-js/wasm-graphviz"; 3import { Zstd } from "@hpcc-js/wasm-zstd"; 4 5// Graphviz --- 6async function dot2svg() { 7 const graphviz = await Graphviz.load(); 8 console.log("svg: ", graphviz.dot('digraph G { Hello -> World }')); 9} 10 11dot2svg(); 12 13// Base91 + Zstd --- 14const text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed non risus. Suspendisse lectus tortor, dignissim sit amet, adipiscing nec, ultricies sed, dolor. Cras elementum ultrices diam. Maecenas ligula massa, varius a, semper congue, euismod non, mi. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed non risus. Suspendisse lectus tortor, dignissim sit amet, adipiscing nec, ultricies sed, dolor. Cras elementum ultrices diam. Maecenas ligula massa, varius a, semper congue, euismod non, mi."; 15const data = new TextEncoder().encode(text); 16 17async function compressDecompress() { 18 const zstd = await Zstd.load(); 19 const compressed_data = zstd.compress(data); 20 const base91 = await Base91.load(); 21 const base91Str = base91.encode(compressed_data); 22 23 const compressed_data2 = base91.decode(base91Str); 24 const data2 = zstd.decompress(compressed_data2); 25 const text2 = new TextDecoder().decode(data2); 26 27 console.log("Text Length: ", text.length); 28 console.log("Compressed Length: ", compressed_data.length); 29 console.log("Base91 Length: ", base91Str.length); 30 console.log("Passed: ", text === text2); 31} 32 33compressDecompress();
Quick Migration from v1
v1.x.x
1import { graphviz, wasmFolder } from "@hpcc-js/wasm"; 2 3wasmFolder("https://cdn.jsdelivr.net/npm/@hpcc-js/wasm/dist"); 4 5const dot = "digraph G { Hello -> World }"; 6 7graphviz.dot(dot).then(svg => { 8 const div = document.getElementById("placeholder"); 9 div.innerHTML = svg; 10}); 11 12graphvizVersion.then(version => console.log(version));
v2.x.x
1import { Graphviz } from "@hpcc-js/wasm"; 2 3const dot = "digraph G { Hello -> World }"; 4 5Graphviz.load().then(graphviz => { 6 const svg = graphviz.dot(dot); 7 const div = document.getElementById("placeholder"); 8 div.innerHTML = svg; 9 10 console.log(graphviz.version()); 11});
Notes:
- wasmFolder is no longer needed
- All wasm libraries have the same asynchronous load pattern
const instance = await <Wasm>.load();
v3.x.x
1import { Graphviz } from "@hpcc-js/wasm-graphviz"; 2 3const dot = "digraph G { Hello -> World }"; 4 5Graphviz.load().then(graphviz => { 6 const svg = graphviz.dot(dot); 7 const div = document.getElementById("placeholder"); 8 div.innerHTML = svg; 9 10 console.log(graphviz.version()); 11});
