Multijet is a highly opinionated framework/template for building large Web API monorepos in Typescript. Even if Multijet gives highly opinionated default structure and settings, it is very flexible thanks to its tech stack nature (rather than being a "closed" framework).

Features:

• OpenAPI models and routes code generation

• Microservice monorepo structure

• Very fast and small builds (using ESBuild to bundle each service)

• Optimized for serverless environments

• Portable deploy (integrates AWS Lambda and Dockerfile)

• Powerful CLI to scaffold new projects and generate code

• Support for Node.js and Bun runtimes

• Strict linting and TypeScript-only to ensure safety

• Integrated logging, dependency injection, automatic routing

Stack:

• Fastify: web framework

• ESBuild: bundler and build tool

• Turborepo: fast monorepo management

• npm workspaces: multi project structure

https://github.com/quinck-io/blaze

Blaze is a Go minimal template that provides a starting point for new projects. It is designed to be a simple, yet powerful, foundation for building fast, idiomatic and maintainable HTTP services in Go. The template aims to not be opinionated, following the official Google conventions and the Go standard project layout. The main advantage of blaze is the 100% compatibility with the standard library, making it universal and compatible with all the Go http ecosystem (middlewares, routers, adapters, tracing, serverless…).

Features:

• Fast and very low overhead

• Utility-driven and flexible multi-entrypoint structure

• Simple to use without “hidden magic”

• 100% compatible with the Go http standard library

• Integrated structured logging

• Seamless AWS Lambda compatibility, optimized for fast cold starts

Stack:

• chi: http router (compatible with standard library) 

• chi/middleware: custom and integrated HTTP middlewares

• zerolog: structured logging

• golangci-lint: linter (custom configuration with strict rules)

Meddle is a platform designed to facilitate the connection between diverse data sources and destinations, processing and normalizing data in soft real-time. Meddle integrates sources and destinations with various industrial protocols or communication standards/technologies, including widely used open-source technologies. The software has two main components: the Gateway and the Cloud-based Software as a Service (SaaS). The Gateway is the atomic unit of Meddle, allowing the connection of multiple data sources to multiple data destinations. The SaaS component operates in the cloud, providing a management layer for multiple Gateways and their configurations, thus offering a comprehensive solution for data integration between diverse sources.

Features:

• Integration with industrial protocols: Snap7, Allen Bradley, BacNet, CAN, COAP, Melsec, Modbus, OPC-UA, Omron Fins, MTConnect

• Integration with open source technologies and communication standards: Apache Kafka, AWS SQS, Prometheus MongoDB, SQL, InfluxDB, MQTT, HTTP, REST

• Flexible plugin architecture

• Internal gateway data transform and rule engine

Stack:

• Python: core of the Meddle Gateway

• TypeScript: SaaS Frontend and backend

• Prometheus: monitoring and analysis

• Redis: SaaS datastream Pub/Sub

• WebSockets: SaaS datastream real time logs

• Docker: containerization (gateway and SaaS)

• AWS Cloud: SaaS infrastructure

  • S3, ECS (gateway deployment), EC2, Cognito (authentication)

  • S3, Cognito (authentication), ECS Fargate (deploy)

This experimental software is designed to manage a consistent, high-speed binary data stream from a line optical sensor that provides 3D inline inspection via a TCP socket connection. The system processes the data through analysis and filtering, manages alert mechanisms, and handles data streaming to a client. The latter is responsible for displaying charts and related information in real time, ensuring an effective and responsive user interface. 

The laser sensor is positioned above a material moving on a conveyor belt, performing a multi-point distance measurement. The output of the sensor can be simplified into a list of n numerical values (samples) indicating the distance to the material.

The software is strongly data-driven: all measurements, calculations, and analyses are specifically carried out for the type of data obtained from the sensor and, consequently, from the passing material.

Requirements:

• soft real-time measurements of each sample received from the sensor (very high speed, ~10.000 samples/s)

• web dashboard to visualize in real time the sample graph, manage sensor and user settings

• alerting system that triggers when measures exceeds user limits

Given the very high throughput and the concurrent nature of the software, we chose Go as the language for the server. All internal components communicate with each other via synchronized channels. The server runs a variety of concurrent operations:

• TCP sensor data ingestion 

• TCP sensor command dispatch

• REST API to communicate with the web dashboard

• data parsing, processing and measurement

• Websockets API to stream throttled data to the web dashboard

• check alerting based on measurements

Stack:

• Go: server language

• MongoDB: database to store alerting samples and user settings

• Svelte: web dashboard

• Grafana and Prometheus: internal software metrics and monitoring

This software serves as a centralized orchestration system for a network of spot welder microcontrollers within a local environment. It periodically retrieves data from each welder, enabling real-time monitoring and streamlining the aggregation of this data for future analysis. Designed for portability, the software is sold to users with the microcontrollers for spot welders, ensuring a seamless integration and management experience for users.

Requirements:

• connecting to multiple welder microcontrollers

• retrieving data from each welder REST API

• storing every single spot made by every welding machine, enabling later data analysis

• sending commands and settings to each welder

• managing welder settings backups

• visualizing connected welders, data and their details in a Web interface

• the entire software stack must be easily portable and installable in any server

• license key management

• Over the air updates for every user

Each welder exposes a documented Json HTTP API, enabling the server to easily retrieve and send data from those. 

The server is divided into 3 main components: API (business logic for the web dashboard), Daemon (welders manager) and Worker (single welder data scraper). Each component is decoupled and communicates with each other using an Event Bus.

When adding a new welder the user must specify its IP address, the Daemon then starts a Worker that scrapes data, stores it and manage the welder status.

The software is distributed as a Virtual Machine Disk (VMWare, VirtualBox and Hyper-V), containing the entire tech stack.

Stack:

• React: web dashboard

• Node.js and TypeScript: API, Worker and Daemon

• Go: OTA update manager, License key management

• MongoDB: main database for business logic and welder data

• Redis: cache, Event Bus

• NGINX: reverse proxy

• Docker: containerization for each component

• Debian: OS delivered in the final virtual disk
