I made an IDE plugin for AWS Lambda local dev, debugging and hot-reload

In plain words

MerLoc is an IntelliJ IDEA plugin that enables developers to run and debug AWS Lambda functions locally while they remain connected to remote cloud workflows. It automatically applies local code changes without requiring rebuilds or redeployment, streamlining development for Java-based Lambda functions. The plugin is designed for AWS developers using IntelliJ who want faster iteration cycles during Lambda function development and debugging.

  MerLoc is a live AWS Lambda function development and debugging tool. MerLoc allows you to run AWS Lambda functions on your local while they are still part of a flow in the AWS cloud remote. MerLoc makes it possible to - test your function locally without deploy to the AWS Lambda environment (so no wait for build, package and deploy) - debug your function by putting breakpoints from your IDE - hot-reload updated function on your local automatically to apply changes automatically (so again no wait for build, package and deploy) - run the individual function locally while it is still part of…

  Haystack – an IDE for exploring and editing code on an infinite canvas2024 · haystackeditor.com · ▲546

  Hi HN, we’re building Haystack Editor (https://haystackeditor.com/), a canvas-based IDE that automates the boring stuff (plumbing, refactoring, and finding code) so that you can focus on the exciting parts of software development! You can see a quick overview of Haystack at https://www.youtube.com/watch?v=c2uZnR5D_cc! (It's currently only on Mac OS but we're working on Linux and Windows. Edit: just added a Linux download!) Haystack was born out of our frustrations with working in large and mature codebases, specifically with navigating and editing functional…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…
