    SurveyJS

    SurveyJS

    JavaScript Survey and Form Library

    SurveyJS Form Library is distributed as npm packages and as scripts and style sheets that you can reference on your page. You can use it in any React, Angular, Vue, Knockout, or jQuery application. React, Angular, Knockout, and Vue3 are supported natively. To communicate with the server, the libraries use JSON objects that represent form schemas (content and layout of a form) and form results (answers). You have the option to build dynamic JSON-driven forms using our free full-featured form builder demo available on the website. Alternatively, you can integrate the form builder library and create forms using a drag-and-drop UI directly within your own application. With years of development and support behind us, we've assisted hundreds of companies across various industries. With Survey, you can create nearly anything that popular cloud services offer. Furthermore, our library is fully extensible, allowing you to modify its behavior to suit your specific needs.

    tmi.js

    tmi.js

    Javascript library for the Twitch Messaging Interface

    Connect to and interact with Twitch chat (IRC) from Node.js or a browser. Control the delay in milliseconds between JOIN requests when using the channels array option. Minimum of 300 milliseconds. If the identity has special permission from Twitch for a higher join rate then you should implement your own calls to the client.join method. Disable receiving JOIN/PART events for other users. Good for decreasing network traffic when joining lots of channels or you don't care about this data. After a threshold per channel Twitch stops sending this data so it may not be necessary for all cases. Channels to automatically join upon connecting. The rate of joins is controlled by the options.joinInterval option. Automatically reconnect the client if it gets disconnected for any reason. Sometimes Twitch will request the client to reconnect and tmi.js will disconnect and reconnect even if this option is set to false.

    Eris

    Eris

    A NodeJS Discord library

    A Node.js wrapper for interfacing with Discord. You will need NodeJS 10.4+. If you need voice support you will also need Python 2.7 and a C++ compiler. Create a directory for your bot, and change to that directory in your command line. If you want to be more updated (at the expense of stability), you can install the beta builds instead. Eris supports a few optional libraries that could potentially improve bot performance but may require additional dependencies. If you want Eris to use any of these packages, install them in the same directory as Eris, and Eris will automatically use them. You can find more examples on the GitHub repo. The rest of the docs will help you with using the various functions of the library. Have fun!

    iView Weapp

    iView Weapp

    A set of high-quality WeChat applet UI component library

    Use WeChat to scan and experience the example of small program components. Before you start using iView Weapp, you need to read the micro-channel applet custom components related documents. We have built-in examples of all components, you can scan the small program code experience on the right, or view it in WeChat developer tools. Then, the examplesdirectory can be opened in the micro-channel developer tools. We adopted a 24-grid system to divide the area into 24 equal parts, which can easily deal with most layout problems. Using the grid system for web page layout can make the page layout beautiful and comfortable. The grid contains 4 components: i-grid, i-grid-item, i-grid-icon, i-grid-label, among them, i-grid-icon and i-grid-label have customized styles by default, but These two components can also be eliminated in development.
