Example

You can use this with nodejs to seed your database.

const child = require('child_process');
...
const cmd = `faker-cli -l 100 "{ username, email }"`;
child.exec(`${cmd}`, (err, stdout, stderr) => {
    if (stdout.length > 0) {
        stdout.split("\n").forEach(item => storeData(item))
    }
});

function storeData(data) {
    db.user.create({
        data: JSON.parse(data)
    }).then(res => console.log(res))
    .catch(err => {})
}

Or you also can use it for automating curl.

faker-cli -l 100 "{ username, email, password }" | xargs -I % sh -c 'curl -X POST http://localhost:8080/register -d "%s"'
