Synchronous Data Generation

Generate CSV data synchronously. This is useful for small datasets that can be generated and used on the fly without the need for asynchronous handling.

const generate = require('csv-generate');
let output = generate({length: 2});
console.log(output);

Asynchronous Stream Generation

Generate CSV data asynchronously using streams. This method is suitable for larger datasets or when the data generation process is part of a larger, asynchronous workflow.

const generate = require('csv-generate');
const generator = generate({length: 20, objectMode: true});
generator.on('readable', function(){
  let row;
  while ((row = generator.read()) !== null) {
    console.log(row);
  }
});

Custom Column Options

Customize the columns of the generated CSV data. This feature allows for specifying the type of data each column should contain, providing flexibility in the structure of the generated data.

const generate = require('csv-generate');
const output = generate({columns: ['int', 'bool'], length: 2});
console.log(output);
