graphql-subscriptions
A small module that implements GraphQL subscriptions for Node.js
GraphQL subscriptions is a simple npm package that lets you wire up GraphQL with a pubsub system (like Redis) to implement subscriptions in GraphQL. You can use it with any GraphQL client and server (not only Apollo). To begin with GraphQL subscriptions, start by defining a GraphQL Subscription type in your schema. Next, add the Subscription type to your schema definition. Now, let's create a simple PubSub instance - it is a simple pubsub implementation, based on EventEmitter. Alternative EventEmitter implementations can be passed by an options object to the PubSub constructor. Now, implement your Subscriptions type resolver, using the pubsub.asyncIterator to map the event you need. When publishing data to subscribers, we need to make sure that each subscriber gets only the data it needs. -

ms
Tiny millisecond conversion utility
Use this package to easily convert various time formats to milliseconds. Works both in Node.js and in the browser. If a number is supplied to ms, a string with a unit is returned. If a string that contains the number is supplied, it returns it as a number (e.g.: it returns 100 for '100'). If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned. For added safety, we're using Template Literal Types (added in TypeScript 4.1). This ensures that you don't accidentally pass ms values that it can't process. This won't require you to do anything special in most situations, but you can also import the StringValue type from ms if you need to use it. -

node-markov-generator
Generates simple sentences based on given text corpus
This simple generator emits short sentences based on the given text corpus using a Markov chain. To put it simply, it works kinda like word suggestions that you have while typing messages in your smartphone. It analyzes which word is followed by which in the given corpus and how often. And then, for any given word it tries to predict what the next one might be. Here you create an instance of TextGenerator passing an array of strings to it - it represents your text corpus which will be used to "train" the generator. The more strings/sentences you pass, the more diverse results you get, so you'd better pass like hundreds of them, or even more! If you have your texts in an external file, you can pass the path to it as an argument for TextGenerator's constructor. -

qwik
The HTML-first framework. Instant apps of any size with
Qwik does not do hydration because it is resumable. Hydration can take several seconds, depending on the complexity of your application and mobile device speed. Qwik applications are instantly interactive even on slow mobile devices leading to a perfect Google PageSpeed score. Qwik apps begin their life as SSR/SSG. Qwik serializes the application's state and framework state into HTML upon rendering the application. Then Qwik can resume execution where the server left off in the browser because all the data Qwik needs is in HTML. No JS needs to be downloaded or executed until it is needed to handle user interaction or rendering. Never think about lazy-loading of your code again. Qwik was built around lazy loading as its core primitive and took it to a whole new level with zero effort for the developer. Event listeners, rendering function, side-effects, creation blocks, it all gets lazy-loaded on an as-needed basis.
