Sentry (Debug In Prod)

Add the sdk and it will automatically capture any fatal errors

As of May 2020, must wait about an hour after project is created to use

Javascript

All javascript libs have the same API:

@sentry/electron | @sentry/browser | @sentry/node

import * as Sentry from "@sentry/browser";

if(process.env.NODE_ENV === "production") {
  Sentry.init({dsn: "https://[hi]@sentry.io/2590109"});
}

If Sentry.init isn't called, all other Sentry functions are noops

Manually Logging

import * as Sentry from "@sentry/electron";

try {
    aFunctionThatMightFail();
} catch (err) {
    Sentry.captureException(err);
}

Sentry.captureMessage('Something went wrong');

Adding Context in General

Can add id, username, email, or ip_address

Don't add extra objects of arbitary size as they will be rejected if over 100KB

Sentry.configureScope((scope) => {
  scope.setUser({"email": "[e-mail]"});
}); //will be for all messages

Sentry.setContext("profile", { name: "Jorge", time: 1 });

Adding Context for a Message

Sentry.captureException(new Error("something went wrong"), {
  extra: {
    section: "articles",
  },
});

Creating Error Popup

  Sentry.init({
    dsn: "https://[e-mail]/2898629",
    beforeSend(event, hint) {
      // Check if it is an exception, and if so, show the report dialog
      if (event.exception) {
        Sentry.showReportDialog({ eventId: event.event_id });
      }
      return event;
    }
  });

Server-Side

Elixir

    {:sentry, "8.0.0"},
    {:jason, "~> 1.1"},
    {:hackney, "~> 1.8"},
    # if you are using plug_cowboy
    {:plug_cowboy, "~> 2.3"},

Usage

Node Specific

const express = require('express');
const app = express();
const Sentry = require('@sentry/node');

Sentry.init({ dsn: 'https://[e-mail]/5182247' });

// The request handler must be the first middleware on the app
app.use(Sentry.Handlers.requestHandler());

// All controllers should live here
app.get('/', function rootHandler(req, res) {
  res.end('Hello world!');
});

// The error handler must be before any other error middleware and after all controllers, by default only captures 500
app.use(Sentry.Handlers.errorHandler());

// Optional fallthrough error handler
app.use(function onError(err, req, res, next) {
  // The error id is attached to `res.sentry` to be returned
  // and optionally displayed to the user for support.
  res.statusCode = 500;
  res.end(res.sentry + "\n");
});

app.listen(3000);

To capture all errors instead of just over 500

app.use(
  Sentry.Handlers.errorHandler({
    shouldHandleError(err) {
      return true; //by default only captures 500, but lets capture all errors
    }
  })
); //must be first error handler and after all controllers
