Install on GCF

Aspecto supports instrumenting Google Cloud Functions (GCF) using an HTTP trigger. To do so, set up Aspecto as you'd usually do, and extract the gcf utility:

const { gcf } = require('@aspecto/opentelemetry')();

Next, wrap your function handler definition with the returned utility. Example:

// Before
exports.myEndpoint = (req, res) => { ... };
​
// After
exports.myEndpoint = gcf((req, res) => { ... });

If your export is an express app, you can still wrap it with the gcf utility, like this:

const { gcf } = require('@aspecto/opentelemetry')();
const express = require('express');
​
const app = express();
app.use('/users/:id', getUser);
app.use('/users/', getAllUsers);
​
// Set your GCF handler to your Express app and wrap it with the "gcf" utility.
exports.users = gcf(app);

Note: if your GCF is not deployed with a package.json file, make sure to provide the packageName option when initializing Aspecto.
