oclif VS serverless-websockets-quest

oclif is a library that helps create CLI applications using Node.js. If you are using a different programming language, search for a suitable library.

It is possible, oclif is a full featured framework produced by Salesforce and is used for the Salesforce and Heroku CLI applications. I have used oclif and pkg to bundle a standalone, though I was focused on MacOS not Windows. Any node application should work with pkg, though.

Interesting. TIL about the Open CLI framework that they all seem to be moving to: https://oclif.io/

https://oclif.io is a tool that helps you build command line tools with node. You can use it to help you create an executable for Linux, max, or windows that you can invoke from the command line.

Oclif to quickly click together CLI tools for kicking off and monitoring crawls, generating reports, etc.

During the second Ably Innovation Days, I started working on specifications for an Ably CLI. After the first day Phil and I started with a prototype based on oclif. We managed to create a working prototype in a day that lists Ably apps, and creates a new Ably app. This project is still Work In Progress. Once the CLI is in a releasable state, I'll create some content around this.

A command-line interface, often referred to as a CLI, is a program that allows users to type instructions and interact with a script that processes the input and produces an output. Node.js has a lot of packages that allows you to build CLIs, like args, minimist, and oclif.

Live demo

Hi all, I created a web app (ADnD style mini game) recently to demonstrate how to use serverless WebSockets (Ably) and combine it with Azure Functions to send realtime updates to the client (based on VueJS and hosted on Azure Static Web Apps). The Azure Functions use Durable Entities (part of Durable Functions) to store a centralized game state, and as soon as the state is updated the clients are notified of this change. Full blog post is here, the game can be played here, and you can have look at the code on GitHub.
