xterm-wasm-parts

Project to hold wasm sources used in xterm.js.

Currently the following primitives are built:

• base64 decoder & encoder
• QOI image format decoder & encoder

The npm package contains only the final wasm definitions and type declarations and can be used like this:

$> npm i --save-dev xterm-wasm-parts

in your source code (example showing base64 decoder):

import Base64Decoder from 'xterm-wasm-parts/lib/base64/Base64Decoder.wasm';
const b64Decoder = new Base64Decoder();      // use defaults for keepSize, maxBytes, initialBytes
...
b64Decoder.init();                           // init decoder (pulls wasm instance)
const data = new Uint8Array([65,65,65,65]);
b64Decoder.put(data);                        // == AAAA == \x00\x00\x00 decoded
b64Decoder.end();                            // end of chunk inputs
b64Decoder.data8;                            // --> Uint8Array(3) [ 0, 0, 0 ] == \x00\x00\x00
b64Decoder.release();                        // releases memory only if maxBytes exceeded
...
b64Decoder.init();                           // init decoder for next data to be decoded

Note that the wasm files are compiled as CJS.
