You can become a serverless blackbelt. Enrol to my 4-week online workshop Production-Ready Serverless and gain hands-on experience building something from scratch using serverless technologies. At the end of the workshop, you should have a broader view of the challenges you will face as your serverless architecture matures and expands. You should also have a firm grasp on when serverless is a good fit for your system as well as common pitfalls you need to avoid. Sign up now and get 15% discount with the code yanprs15!
- it’s more fun
- you can take advantage of Dart’s support for static type checking
- you can make use of Dart’s isolates (think F# mailbox or Erlang processes, isolates is Dart’s implementation of Carl Hewitt’s actor model) to abstract over making concurrent requests and handling retries, etc.
- it’s more fun!
Update 05/07/2014 : I had previously stated that raven-js had dependencies on jQuery, ember, etc. that was incorrect. As they were in fact raven-js plugins for those frameworks (as stated in its Plugins documentation page here) and the raven-js itself doesn’t have any dependencies.
Operational params can be used to customize the behaviour of captureMessage and captureException, such as adding tags, or other metadata to go along with the events.
Following the official guidelines on writing a Sentry client, the library supports:
- DSN configuration via constructor argument
- null means disabled
- Graceful failure handling
- fallback to logging to console when Sentry is disabled
- retry on error (except for HTTP status codes 400, 401, 403, and 503)
- configurable max no. of retries
- exponential delay when retrying
- temporarily disable if Sentry is unavailable (503)
- Support for tagging
- common tags can be provided in the client constructor
- additional tags are supplied for each event
- when common and event-specific tags overlap, both are sent as part of the event
- Non-blocking event submission
- events are sent to available isolates in round-robin fashion, whom then process them asynchronously and concurrently
- configurable level of concurrency per core which determines number of isolates running at the same time
- Basic data sanitization/scrubbing
- credit card number-like fields are scrubbed
- Sentry key and secrets are scrubbed
- Values that look like passwords or secrets are scrubbed
Please give it a try and let me know what you think, if you find any bugs or have feedbacks in general, feel free to add them to the issues page.
Hi, I’m Yan. I’m an AWS Serverless Hero and I help companies go faster for less by adopting serverless technologies successfully.
Are you struggling with serverless or need guidance on best practices? Do you want someone to review your architecture and help you avoid costly mistakes down the line? Whatever the case, I’m here to help.
Skill up your serverless game with this hands-on workshop.
My 4-week Production-Ready Serverless online workshop is back!
This course takes you through building a production-ready serverless web application from testing, deployment, security, all the way through to observability. The motivation for this course is to give you hands-on experience building something with serverless technologies while giving you a broader view of the challenges you will face as the architecture matures and expands.
We will start at the basics and give you a firm introduction to Lambda and all the relevant concepts and service features (including the latest announcements in 2020). And then gradually ramping up and cover a wide array of topics such as API security, testing strategies, CI/CD, secret management, and operational best practices for monitoring and troubleshooting.
If you enrol now you can also get 15% OFF with the promo code “yanprs15”.
Check out my new podcast Real-World Serverless where I talk with engineers who are building amazing things with serverless technologies and discuss the real-world use cases and challenges they face. If you’re interested in what people are actually doing with serverless and what it’s really like to be working with serverless day-to-day, then this is the podcast for you.
Check out my new course, Learn you some Lambda best practice for great good! In this course, you will learn best practices for working with AWS Lambda in terms of performance, cost, security, scalability, resilience and observability. We will also cover latest features from re:Invent 2019 such as Provisioned Concurrency and Lambda Destinations. Enrol now and start learning!
Check out my video course, Complete Guide to AWS Step Functions. In this course, we’ll cover everything you need to know to use AWS Step Functions service effectively. There is something for everyone from beginners to more advanced users looking for design patterns and best practices. Enrol now and start learning!
