    Cabin

    Cabin

    Cabin is the best JavaScript and Node.js logging service and logging

    Cabin is the best JavaScript and Node.js logging service and logging npm package. Cabin is a drop-in replacement and the best alternative to Sentry, Timber, Airbrake, Papertrail, Loggly, Bugsnag, etc. Cabin will automatically detect and mask the following list of extremely sensitive types of data in your logs. Reduce your disk storage costs through Cabin's automatic conversion of Streams, Buffers, and ArrayBuffers to simplified, descriptive-only objects that otherwise would be unreadable (and obviously pollute your log files and disk storage). Cabin works with the most popular Node.js HTTP frameworks (e.g. Express and Koa), request body handling packages (e.g. multer and body-parser), and the passport authentication framework. It supports Node v6.4+ and IE 10+ out of the box, and its browser-ready bundle is only 39 KB (minified and gzipped).

    CanJS

    CanJS

    Build CRUD apps in fewer lines of code

    Components shouldn’t be concerned with how data is fetched, updated, or cached. CanJS provides the right abstractions for your model code to be cleanly separated from your UI code. CanJS’s stache templating language can directly read the state and values from Promises. No need to write any extra code to determine whether a Promise is pending, resolved, or rejected. After data is created, updated, or destroyed, CanJS automatically updates your lists for you. Filtering and sorting are preserved, so you don’t have to manually update your lists or fetch the same data again. The model layer is responsible for making GET, POST, PUT, and DELETE requests to your backend. With your component UI code using the model’s standard interface to make requests, if the backend API changes, you only have to configure the model and not change every component that uses that backend API.

    Catberry

    Catberry

    Catberry is an isomorphic framework

    Catberry is an isomorphic framework for building universal front-end apps using components, Flux architecture and progressive rendering. Catberry builds a bundle for running the application in a browser as a Single Page Application. Cat-Components – similar to web-components but organized as directories, can be rendered on the server and published/installed as NPM packages. The entire architecture of the framework is built using the Service Locator pattern, which helps to manage module dependencies and create plugins, and Flux, for the data layer. Search crawler receives a full page from the server. The whole state of the application is restored from URL. Server-side progressive rendering based on node.js streams and parallel rendering of components in a browser. The framework is well-tested (code coverage is about 90%) and it is already used in production.

    ClassyVision

    ClassyVision

    An end-to-end PyTorch framework for image and video classification

    Classy Vision is a PyTorch-based framework designed for large-scale training and deployment of state-of-the-art image and video classification models. Developed by Facebook Research, it serves as an end-to-end system that simplifies the process of training at scale, reducing redundancy and friction in moving from research to production. Unlike traditional computer vision libraries that focus solely on modular components, Classy Vision provides a complete and unified framework, featuring distributed training, reproducible experiments, and flexible configuration tools. It offers high performance and scalability—capable of training models like ResNet-50 on ImageNet in just minutes—while remaining accessible to both researchers and production engineers. The library integrates seamlessly with PyTorch Hub for easy access to pretrained models and supports elastic training using PyTorch Elastic, making distributed training robust to changes in cluster resources or hardware failures.

    Claudia Bot Builder

    Claudia Bot Builder

    Create chat bots for Facebook Messenger, Slack, Amazon Alexa, etc.

    Claudia Bot Builder helps developers create and deploy chat-bots for various platforms in minutes to AWS Lambda. It simplifies the messaging workflows, automatically sets up the correct web hooks, and guides you through configuration steps, so that you can focus on important business problems and not have to worry about infrastructure code. This code is enough to operate bots for all supported platforms. Claudia Bot Builder automatically parses the incoming messages into a common format, so you can handle it easily. It also automatically packages the response into the correct message template for the requesting bot, so you do not have to worry about individual bot protocols. Claudia Bot Builder doesn't have a stand-alone http server in the background (such as Express, Hapi, etc.), instead it uses API Gateway and it's not trivial to simulate similar environment locally. Deploy it with --version test to create a separate test environment directly in AWS Lambda.
