Vircadia Web SDK

The Vircadia Web SDK (codename Ananke) is a JavaScript/TypeScript SDK for developing web-based applications for virtual worlds powered by the open source metaverse platform Vircadia. Vircadia domain servers provide the worlds (a.k.a. "domains") to visit, and the Vircadia metaverse server provides global services that connect the users and domains. See the user docs to Understand the Architecture.

This SDK provides interfaces to:

• Connect to domains.
• Use metaverse services.

The SDK is written in TypeScript.

• Project Configuration
• Coding Standard

The SDK is published at NPM: https://www.npmjs.com/package/@vircadia/web-sdk

To learn more about using Vircadia's metaverse ecosystem, see the Developer Documentation.

Prerequisites

Node.js

https://nodejs.org/en/download/

Node.js version ≥ 10.13 ; LTS version ≥ 14.16 recommended
npm version ≥ 6.4.1 ; LTS version ≥ 6.14 recommended

Jest

Jest is used for unit testing. It is included as an NPM dev dependency, however, you may also install it globally if you want to.

Project Setup

Get the source

git clone https://github.com/vircadia/vircadia-web-sdk.git

If you're working on Vircadia protocol code (that in the \src\domain directory) it is recommended that you clone the SDK as a subdirectory of the main Vircadia repo's source so that both sets of code are accessed when you open the main Vircadia repo's source in your IDE. For example, if your clone of the main Vircadia repo's source is in C:\Workspaces\vircadia then clone the SDK repo's source into C:\Workspaces\vircadia-web-sdk. Thus with the main Vircadia's repo loaded in your IDE, when you search for code then both C++ and TypeScript results are returned, helping you compare the two codebases and keep them in sync.

Note: Unix line endings (LF, 0A character) are used. If using Windows it is recommended that you configure Git's global setting core.autocrlf to be true. This makes the files use Windows line endings (CRLF, 0D0A characters) on your computer but stores the files in the Git repo with Linux line endings.

Install NPM packages

npm install

Loads all the supporting NPM packages as defined in package.json into the node_modules directory.

Development and Testing

Compile and minify for development

npm run build

Does a development compile and packages the SDK into the dist directory.

Hot-recompile for development

npm run watch

Does a development compile and enables webpack to watch the sources and recomile when source files change. This is often useful when testing SDK development using the example tool.

Compile and minify for production

npm run build-prod

Does a clean production compile and packages a releasable version of the SDK into the dist directory.

Hot-recompile for production

npm run watch-prod

Does a clean production compile and enables webpack to watch the sources and recompile when the source files change.

Clean the build directory

npm run clean

Lint files

All files:

npm run lint

A specific directory or file:

npm run lint-path <path>

Run tests

Unit tests can be run without any external dependencies but integration tests require a domain server to be running on localhost or other location specified in ./tests/test.config.json. The location and other values of the config JSON can be overridden with environment variables, using the same property names, but prefixed with "VIRCADIA_".

All tests:

npm run test

Hot retest of all tests:

npm run test-watch

Specific tests (e.g., Packet.unit.test.js, all unit tests, all integration tests):

npm run test <partial-path>

npm run test /packet.unit
npm run test .unit.
npm run test .integration.

Run tests and report open handles:

npm run test-debug [<partial-path>]

Generate docs

SDK API documentation:

npm run sdkdoc

Developer documentation (includes SDK API documentation):

npm run devdoc

Update contributors

Update contributors list in package.json:

npm run update-contributors
