Read and write CSV files (JavaScript)

Ready to see some code?

Here's an example of transforming a CSV file using JavaScript:

const { readCsv, writeCsv } = require("daki");

function transform(record) {
    // Your function to transform a data record.
}

async function main() {
    const data = await readCsv("./some/file.csv");
    const transformed = data.map(transform);
    await writeCsv("./an/output/file.csv");
}

main()
    .then(() => console.log("Done"))
    .catch(err => {
        console.error("Something went wrong.");
        console.error(err && err.stack || err);
    });

Read and write JSON files (TypeScript)

Here's a similar code example using TypeScript.

This time we are reading and writing JSON files:

import { readJson, writeJson } from "daki";

function transform(record: InputT): OutputT {
    // Your function to transform a data record.
}

async function main(): Promise<void> {
    const data = await readJson("./some/file.json");
    const transformed = data.map(transform);
    await writeJson("./an/output/file.json");
}

main()
    .then(() => console.log("Done"))
    .catch(err => {
        console.error("Something went wrong.");
        console.error(err && err.stack || err);
    });
