- Mock2CSV is a simple library that allows you to quickly create csv files using libraries like faker.js.
- Recommend to use Typescript.
- Can use bcryptjs, faker-js, moment-timezone by
import { bcrypt, faker, moment } from "mock2csv";
It has some options.
const m2c = new Mock2CSV(); // default
const m2c = new Mock2CSV({ header: false, logging: false }); // disable header, logging
const m2c = new Mock2CSV({ delimiter: ";" }); // use delimiter ';'
// you can set options by setter.
m2c.setOptions({ header: false });
m2c.setNewLine(" ");interface Options {
header: boolean;
delimiter: string;
quote: string;
escape: string;
newLine: string;
logging: boolean;
}-
header- default :
true - Add a line at the top of the CSV file that spells out the name of each column.
- default :
-
delimiter- default :
, - Separator for each
columnin the record.
- default :

\n - Signals the end of the record line and separates the next record statement.
- default :
-
logging- default :
false - Enable/disable logging for this tool.
- default :
import { bcrypt, faker, moment, Mock2CSV, Schema } from "mock2csv";
let user_id = 1;
const pw = bcrypt.hashSync("password123", 10); // encrypt password (encryption is time-consuming)
const User: Schema = {
userId: () => (user_id++).toString(),
nickname: () => faker.internet.userName(),
email: () => faker.internet.email(),
password: () => pw,
createdAt: () =>
moment().tz("Asia/Seoul").format("YYYY-MM-DDTHH:mm:ss.SSSSSSZ"),
updatedAt: () =>
moment().tz("Asia/Seoul").format("YYYY-MM-DDTHH:mm:ss.SSSSSSZ"),
};
const m2c = new Mock2CSV();
// apis
m2c.generate(User, 1e3, "output.csv");
await m2c.generateAsync(User, 1e5, "output.csv");
m2c.generateToStream(User, 1e3, stream);- output.csv result example
