Scrubbr
Serialize JSON data using TypeScript.
Serializing data sent from the webserver to the client shouldn't be hard. If you're already using TypeScript, you have everything you need. Scrubbr will use your TypeScript types to deeply transform and sanitize your data.

Install
npm i -S scrubbr
Quick Start
The simplest example is to filter out sensitive data.
In this example we want to filter the email and password out of this sample data:
{
users: [
{
name: 'John Doe',
image: 'http://i.pravatar.cc/300',
email: 'donotspam@me.com',
password: 'xxxsecretxxx',
},
],
};
- Define a TypeScript file as your master schema:
type UserList = {
users: User[];
};
type User = {
name: string;
image: string;
};
- Load it into Scrubbr and serialize your data:
import Scrubbr from 'scrubbr';
const scrubbr = new Scrubbr('./schema.ts');
function api() {
const data = getUsers();
return scrubbr.serialize('UserList', data);
}
- Ouput
{
"users": [
{
"name": "John Doe",
"image": "http://i.pravatar.cc/300"
}
]
}
Express Middleware
To make things even easier in express, install the Scrubbr express middleware.
app.get('/users', (req, res) => {
const userData = fetchDataHere();
resp.status(200)
.scrubbr('UserList')
.send(userData);
}
