AI Favorites🦾:

1. CopilotKit - In-app AI chatbots and AI Textareas

Image description

Open-source platform for integrating key AI features into react apps using two react components.

CopilotPortal: in-app AI chatbots that can "see" the current app state and take actions.
CopilotTextarea: AI-powered replacement. With autocomplete, insertions and generations.

Good First Issue:

Gracefully fail if CopilotProvider is omitted 


The bug:

Virtually every CopilotKit functionality depends on a CopilotContext provided by the CopilotProvider. e.g. CopilotTextarea autocompletions, chatbot, etc. 
However when a CopilotProvider does not wrap the component, functionality fails silently.  


To Reproduce   

1. Omit <CopilotProvider>...</CopilotProvider> 
2. trigger useMakeCopilotReadable, useMakeCopilotActionable, CopilotTextarea, CopilotSidebarUIProvider 
3. See how functionality does not work, but no error is emitted 

Expected behavior An error is emitted, with clear description of the likely core issue and how to resolve it (namely, wrap the app in a CopilotProvider). Point to docs.

6. Winglang - Cloud Oriented Programming Language

Image description

Wing is a programming language for cloud apps.

It combines code for cloud infrastructure and applications, making cloud service development easier.

Wing's unique execution model and testing simulator help build and deploy cloud apps efficiently.

Good First Issue:

Support Array.sort() method

Feature Spec:

let arr: MutArray<num>=[2, 1, 3, 9, 6, 4]; 
arr.sort(); 
log("${arr}");  // it should print sorted array in ascending order, eg: [1, 2, 3, 4, 6, 9] 

Component:
Wing SDK  

Community Notes: 

If you are interested to work on this issue, please leave a comment. If this issue is labeled needs-discussion, it means the spec has not been finalized yet. Please reach out on the #dev channel in the Wing Slack.

15. Cerbos - Scalable, Language-Agnostic Authorization

Image description

Cerbos offers unique, scalable solutions for implementing context-specific user permissions in applications.

Its flexible, language-agnostic approach allows for easy integration and management of complex authorization structures.

Distinctively, Cerbos simplifies the development of access control policies, making them more adaptable to various application needs.

Good First Issue:

Produce output when the rule condition is not satisfied

Currently the output block is only evaluated if the rule is actually activated (action, roles and conditions are satisfied). 
In certain situations, it's desirable to produce output when the rule is nearly activated (action and roles match but the condition is not satisfied).

In order to maintain backward compatibility, reduce noise, and to keep policy execution as fast as possible (outputs incur a tiny overhead), the proposal is to let users add an optional when section to the output block to opt into this behaviour.

    - actions: ['view']
      effect: EFFECT_ALLOW
      roles: ['user']
      condition:
        match:
          expr: timestamp(R.expiry_date) > now()
      output: 
        expr: >
          format("%d hours until expiry", (timestamp(R.expiry_date) - now()).getHours())
        when:
          cond_fail: >
            format("expired on %s", R.expiry_date)
When evaluating the above rule,

if the action, roles and condition match, output will be the result of evaluating output.expr
If the condition is not satisfied, output will be the result of evaluating output. when.cond_fail if it exists. Otherwise no output will be produced.

Good First Issue:

Add a Connector: Yahoo search

It would help to search anything with Swirl on Yahoo effectively.

Locate and read a bit in their search API first. You might just need to make a new SearchProvider configration vs. a new Connector. Their docs should help guide you a bit in which way you might need to go.

25. Wasp - Develop full-stack web apps with React & Node.js

Image description

Rapid Full-Stack Web App Development with React & Node.js.

Wasp offers a simplified approach to building modern web applications, combining React for front-end and Node.js for back-end in a cohesive framework.

Good First Issue:

Add images (or link to the example app) of auth UI helpers Wasp provides

At this point in docs (also in the tutorial if we're using it), it would be nice to add an image of UI helpers for Auth (login/signup form, Google/GitHub button, ...) so developers can immediately see what they are getting and how nice it looks.
