## Installation and example
|
|
|
|
```bash
|
|
bun install czv
|
|
```
|
|
|
|
Or use `npm`, `pnpm`, or `yarn` instead of `bun`.
|
|
|
|
```ts
|
|
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: number = czv.rowCount({
|
|
file_data: data,
|
|
include_header_row: true,
|
|
});
|
|
|
|
console.log(output);
|
|
```
|
|
|
|
## Development
|
|
|
|
You must have [wasm-pack](https://rustwasm.github.io/wasm-pack/installer/) installed. If you have Cargo installed you may run:
|
|
|
|
```bash
|
|
cargo install wasm-pack
|
|
```
|
|
|
|
### Build WASM for web
|
|
|
|
```bash
|
|
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
|
|
|
|
```bash
|
|
wasm-pack test --firefox --release
|
|
```
|
|
|
|
You may replace `--firefox` with another browser such as `--chrome` and `--safari`.
