Echoing the request

FaasPlus allows you to effortlessly manipulate incoming data. Whether you're adding additional fields, transforming data, or modifying structures, the flexibility of FaasPlus makes this process extremely straightforward. Let's dive into how simple it is to manipulate data using some practical examples.


Example 1: Adding a Timestamp

In this example, we'll add an execution timestamp to the data received in the request body.


Run in postman 
const handleRequest = async (req) => {
    let res={...req.body};
    res['ExecutedAt']=new Date();
    return res;
}
body (as json) 
{
    "FullName": "Alan Turing"
}

>response
{
    "ExecutedAt": "2024-10-03T06:15:45.991Z",
    "FullName": "Alan Turing"
}

Example 2: Renaming Fields

In this example, we'll rename a field from "Name" to "FullName" in the incoming request.


Run in postman 
const handleRequest = async (req) => { 
    let res = {}; 
    res['FullName'] = req.body.Name; 
    return res; 
};
body (as json) 
{
    "Name": "Alan Turing"
}

>response
{ 
    "FullName": "Alan Turing" 
}

Here, we take the "Name" field, rename it to "FullName," and return the updated object. This type of manipulation can be useful when you need to adjust or standardize field names between systems.


Example 3: Combining Fields

In the following example, we'll combine two fields from the request body into one.


Run in postman 
const handleRequest = async (req) => { 
    let res = {}; 
    res['FullName'] = req.body.FirstName + ' ' + req.body.LastName;
    return res;
};
body (as json) 
{
    "FirstName": "Alan",
    "LastName": "Turing"
}

>response
{ 
    "FullName": "Alan Turing" 
}
