The latest stable major version is v4. There are many breaking changes from v3.

Please consult the update guide for help migrating your code.

Documentation

For documentation complete with examples, please see the Skynet SDK docs.

We also have an introduction workshop for building a web app on Skynet, and an example tutorial about creating your app without a Javascript framework.

How To Use skynet-js In Your Web Project

If you're thinking, "wait, how can I import() in the browser," then here is the answer:

While skynet-js is built with Node.js, you can easily compile it to one minified javascript file that is compatible with browsers.

Webpack will compile only the used functions (unused code will be removed automatically), so it is recommended to build your whole project in Node.js and compile it with webpack (click here for detailed tutorial):

cd your_project

npm install skynet-js

npm install webpack webpack-cli --save-dev

Update your package.json file.

remove - "main": "index.js",
add    - "private": true,

Create folders mkdir dist src. Make sure you have your javascript files in src and the main (entry) javascript is named index.js.

Compile with npx webpack! You will find the minified main.js in the dist folder.

Development

• Clone the repository
• Run yarn
• Run yarn prepare to install pre-commit hooks
• Run yarn test to run the tests

Also see our guide to contributing.

Requirements

We have some automated checks that must pass in order for code to be accepted. These include:

• Type-checking and other code lints must pass.
• Every function must have a complete JSDoc-style docstring.
• 100% code coverage is enforced. Every statement and conditional branch must be tested.

Note that the 100% coverage requirement is a minimum. Just because a line of code is tested does not mean it is tested well, that is, with different values and combinations of values. Tests should be as thorough as possible, within reason.
