Treblle with Express

To integrate Treblle with Express, we provide an official SDK for Express - treblle-express.

Installation

Terminal window
npm i @treblle/express --save

Setting up credentials

@treblle/express expects your Treblle API key and project ID to be set as environment varibles in a .env file or in your production environment.

Below are the environment variable that will be checked by @treblle/express

  • TREBLLE_API_KEY
  • TREBLLE_PROJECT_ID

Setup middleware

@treblle/express expose a treblle function which returns a middlware, you can pass this function to app.use() to register it a middleware.

const treblle = require('@treblle/express')
const app = express()


app.use(treblle())

Treblle will now now start monitoring requests on your Express server.

Config options

You can optionally pass a config option to the treblle function.

const treblle = require('@treblle/express')
const app = express()


app.use(
  treblle({
    apiKey: process.env.TREBLLE_API_KEY,
    projectId: process.env.TREBLLE_PROJECT_ID,
    additionalFieldsToMask: [],
  })
)

The additionalFieldsToMask config option takes in an array of strings that matches properties in your response payload or header that you want to mask
