Firebase Functions​

Boilerplate Typed Function​

import * as cors from 'cors';
const corsHandler = cors({origin: true});

interface IMyFunctionRequest { 
    data: { 
        userID: string, 
        serialNumbers: string 
    } | undefined;
};

export const myFunction = functions
    .runWith({ timeoutSeconds: 540, memory: "8GB" })
    .https
    .onRequest(async (request: TypedRequest<IMyFunctionRequest>, 
        response: functions.Response) => {

    // Get input data...
    const requestData = request.body.data;
    const userID = (requestData) ? requestData.userID : "";
    const serialNumbers = (requestData) ? requestData.serialNumbers : "";

    // Get data...
    corsHandler(request, response, async () => {
        try 
        {
            // Do something...
            const result = 3;
            response.send({ data: result });
        }
        catch(error: any)
        {
            functions.logger.error("Error", error);
            response.sendStatus(500);
        }
    });
 });

Set Timeout / Memory Allocation​

functions.runWith({ timeoutSeconds: 540, memory: "8GB" })

onUserDelete​

export const onUserDelete = functions
    .runWith({ timeoutSeconds: 540, memory: "8GB" })
    .auth.user().onDelete(async (user: functions.auth.UserRecord) => {
    
    // Tasks (example: delete user records)...
    await admin.database().ref("clients").child(user.uid).remove();
    await admin.firestore().collection("pubsub_nightlyRefresh").doc(user.uid).delete();
    
    return Promise.resolve();
});
