Installation

Download this package:

npm -I coderr.client.expressjs

Import both the Coderr base library and the expressjs package:

import { err } from "coderr.client";
import { activatePlugin, errorMiddleware } from "coderr.client.expressjs";

// in the top of your app.js/ts
err.configuration.credentials("https://report.coderr.io", "yourAppKey", "yourSharedSecret");

// To configure the expressJS plugin.
activatePlugin(err);

// As the last middleware:
app.use(errorMiddleware);

Reporting slow queries.

You can report slow queries and/or all pages that generate 403 (Forbidden).

Add the coderrMiddleware for that:

import * as coderr from "coderr.client.expressjs";

// Either use this to set a limit to all HTTP verbs (in milliseconds)
coderr.requestTimeThreshold = 200;

// or do it per verb:
coderr.requestMethodTimeThresholds['post'] = 200;

// As the *first* middleware:
app.use(coderr.coderrMiddleware);

Reporting forbidden requests

You can report all requests that generate 403 forbidden:

import * as coderr from "coderr.client.expressjs";

coderr.reportForbidden = true;

// As the *first* middleware:
app.use(coderr.coderrMiddleware);
