    electron-store

    electron-store

    Simple data persistence for your Electron app or module

    Simple data persistence for your Electron app or module. Save and load user preferences, app state, cache, etc. Electron doesn't have a built-in way to persist user preferences and other data. This module handles that for you, so you can focus on building your app. You can use this module directly in both the main and renderer process. For use in the renderer process only, you need to call Store.initRenderer() in the main process, or create a new Store instance (new Store()) in the main process. Changes are written to disk atomically, so if the process crashes during a write, it will not corrupt the existing config. Under the hood, the JSON Schema validator ajv is used to validate your config. We use JSON Schema draft-07 and support all validation keywords and formats. You should define your schema as an object where each key is the name of your data's property and each value is a JSON schema used to validate that property.

    express-status-monitor

    express-status-monitor

    Realtime Monitoring solution for Node.js/Express.js apps

    Simple, self-hosted module based on Socket.io and Chart.js to report real-time server metrics for Express-based node servers. Monitor can be configured by passing options object into expressMonitor constructor. You can add a series of health checks to the configuration that will appear below the other stats. The health check will be considered successful if the endpoint returns a 200 status code. The HTML page handler is exposed as a pageRoute property on the main middleware function. So the middleware is mounted to intercept all requests while the HTML page handler will be authenticated. If you're using socket.io in your project, this module could break your project because this module by default will spawn its own socket.io instance. To mitigate that, fill websocket parameter with your main socket.io instance as well as port parameter.

    fela

    fela

    State-driven styling in JavaScript

    Fela generates unique CSS classes for every rule. It automatically sorts rules, pseudo-classes and media queries. This prevents global namespace and specificity conflicts and ensures predictability. You always get the styles you write. Fela generates atomic CSS classes. For every property-value pair there's a single rule which can be reused across your whole application. This limits the amount of rendered CSS and ensures reusability. You only get the styles you actually need. Fela is a plain JavaScript library and works without a framework for our UI library. It ships several bindings for popular tools such as React, Vue, or ReasonML amongst others. With only ~4kb minified and gzipped, Fela is a lightweight styling toolbelt. Yet, it ships with a huge ecosystem consisting of dozens of plugins, enhancers, and third-party packages. You choose the extensions you need.

    goober

    goober

    A less than 1KB css-in-js solution

    As the subtitle notes, this is the smallest and fullest featured css-in-js solution out there. Weighing at 1KB and once bundled it's gonna be less due to tree-shake. goober does more with less! Since the code measure less in size, it's served, read and ran quicker. goober is built on the shoulders of well-established solutions. That means the API has been paved and we need to follow it. You'll find as, forwarded, CSS, keyframes, styled and so much more. Easily access your common sizes, colors, and anything really with the use of a theme. On the server, you can easily extract the CSS for the current state with extractCss. The initial thought of goober was a CSS-in-js solution at the cost of peanuts. Hence the peanuts emoji. By using goober, you are practically getting back space in size to build more of the needed features.

    hapi

    hapi

    The simple, secure framework developers trust

    Build powerful, scalable applications, with minimal overhead and full out-of-the-box functionality. Originally developed to handle Walmart’s Black Friday scale, hapi continues to be the proven choice for enterprise-grade backend needs. When you npm install @hapi/hapi, every single line of code you get has been verified. You never have to worry about some deep dependency being poorly maintained (or handed over to someone sketchy). hapi is the only leading node framework without any external code dependencies. None. hapi has been pushing the envelope on quality from day one. It was the first node framework to require and achieve 100% code coverage across every dependency – when everyone thought it was crazy. Every hapi feature is designed to make the platform easier and more intuitive to use. That means there’s no need to hack things together, experiment to see what *might* work, or try to figure out hidden internals. There is no “magic” – the code does what you expect.
