czv-wasm

WebAssembly (JavaScript and TypeScript) library for czv. czv is a library of CSV-related operations for data engineering and analysis tasks.

Installation and example

bun install czv

Or use npm, pnpm, or yarn instead of bun.

import init, * as czv from "czv";
// Must run `await init()` or `initSync()` first for web use
await init();

const data = `fruits,price
apple,2.50
banana,3.00
strawberry,1.50`;

const output = czv.rowCount({
    file_data: data,
    include_header_row: true,
});

console.log(output);

Development

You must have wasm-pack installed. If you have Cargo installed you may run:

cargo install wasm-pack

Build WASM for web

wasm-pack build --release --target web --out-name czv

Note: Currently you must modify the pkg/package.json by replacing the name from czv-wasm to czv.

Test WASM for browser

wasm-pack test --firefox --release

You may replace --firefox with another browser such as --chrome and --safari.
