With FaasPlus, you can easily manipulate JSON data in your functions

Imagine you receive JSON data with two values, a and b, and you need to calculate their sum. With FaasPlus, it's as simple as writing a few lines of JavaScript.

In this case, FaasPlus extracts the values from the JSON, performs the calculation, and returns the result—all in one seamless function. This showcases how easily FaasPlus handles real-world scenarios where working with JSON data is essential, letting you focus on logic while it manages the heavy lifting.

Run in postman 


curl -X POST https://large1.faasplus.com/acme/demo/sum \
-H 'Content-Type: application/json' \
-d '{"a":10,"b":20}'
                                    
export async function handler(event) {
    const a = event.body?.a || 0;
    const b = event.body?.b || 0;
    const sum = a + b;
    return {
        sum: sum
    };
}
->response 
{
'sum':30
}

Easily Integrate and Call External Services

With FaasPlus, you can effortlessly interact with external APIs and services using JavaScript’s built-in fetch. Whether you're retrieving data from third-party services or posting data to external APIs, FaasPlus gives you the flexibility to seamlessly integrate external resources into your functions. For example, making an HTTP request to fetch external data is as simple as:

Run in postman 


curl -X GET https://large1.faasplus.com/acme/demo/ext-call?postId=1                                        
                                    
export async function handler(event) {
    // Request postId as parameters (query string)
    const postId = event.params?.postId || 1;
    
    // Request external data using global fetch
    const res = await fetch(`https://jsonplaceholder.org/posts/${postId}`);
    
    // Read as JSON
    const jsonRes = await res.json();
    
    // Add additional field
    const executedAt = new Date().toString();
    
    // Compose new result
    const myRes = {
        id: jsonRes.id,
        slug: jsonRes.slug,
        executedAt: executedAt
    };
    
    return myRes;
}
->response 
{
    'id':1,
    'slug':'condimentum.',
    'executedAt':'Wed Sep 11 2024 11:13:10'
}
