Introducing MailCrab!

MailCrab is an email test server for development, written entirely in Rust.
As owner and technical lead of our company I'm very motivated to keep up to speed with all new developments and to continuously innovate our tech stack. Nevertheless, every once in a while I find myself lacking in in-depth, hands-on experience in languages and tools I really want to be on top of. At that moment, I know I need to hit pause and take the time for a deep dive, in the form of a personal learning project.
Als je, net zoals ik, heel graag (lees: bijna dwangmatig) wil maken/bouwen/coderen, dan stopt dat natuurlijk niet als je de deur van kantoor achter je dicht trekt. Ook als ik niet bij Tweede golf ben is er altijd wel iets waaraan ik bezig ben. Mijn meest uit de hand gelopen pet project is toch wel mijn home-automation-system. Mijn appartement is inmiddels behoorlijk slim. Met microservices en al.

MailCrab

MailCrab is an email test server for development, written entirely in Rust.

MailCrab was inspired by MailHog and MailCatcher. It uses Axum for the backend and Yew for the frontend.

RP1

Developed by Ruben, RP1 is a procedural macro that generates a set of useful basic CRUD (Create-Read-Update-Delete) endpoints in a REST-like API with JSON output.

Check out the blog post RP1: an experimental Diesel-based CRUD for Rocket, for more.

TGuard

TGuard is a web-based sending and decrypting service for irmaseal-encrypted messages that is currently in development at Tweede Golf.

TGuard utilizes IRMA to allow a user to encrypt messages client-side. These messages can be decrypted client-side once the receiver proves to be the owner of attributes the message was encrypted for, like an e-mail address, name, or an identifying number.

ID-contact

For ID Contact we researched the possibilities of digital identification: how can residents organize their personal government affairs in a simpler and more reliable way? By telephone, via chat or via a video call.

The ID Contact innovation pilot is a collaboration between the municipalities of Arnhem, Nijmegen and the Drechtsteden and knowledge partners such as the Tax Authorities and iHub (Radboud University).

Within the ID Contact team we developed the software that makes secure digital identification possible.

Cloud storage abstraction for Node.js

Developed by Daniel, storage-abstraction provides an abstraction layer for interacting with a storage; this storage can be a local file system or a cloud storage. Currently local disk storage, Backblaze B2, Google Cloud and Amazon S3 and compliant cloud services are supported.

Also see the related blog post, Cloud storage simplification and abstraction for Node.js or give the npm package a try.
