You can use https://github.com/marak/Faker.js/ which is nice and has a lot of stars on github.

Here is how you generate something basic in the browser

<script src = "faker.js" type = "text/javascript"></script>
<script>
  var randomName = faker.name.findName(); // Caitlyn Kerluke
  var randomEmail = faker.internet.email(); // Rusty@arne.info
  var randomCard = faker.helpers.createCard(); // random contact card containing many properties
</script>

And here is in nodejs

var faker = require('faker');

var randomName = faker.name.findName(); // Rowan Nikolaus
var randomEmail = faker.internet.email(); // Kassandra.Haley@erich.biz
var randomCard = faker.helpers.createCard(); // random contact card containing many properties

If you want to generate data in the database you could write some seeding scripts (and use this to generate some random but controlled data).
