Introduction
Want to build something on top of LBRY? This is the place to get started.
At least, it's the place to get started so long as you have some idea of what LBRY is. If you don't, you should read the Overview first.
Want to build with us rather than on your own? Check out our Contributing Guide.
When to Use LBRY
- You want to build an application that contributes to the world's knowledge, or benefits from global, shared discovery.
- You want to replace an existing centralized service related to digital content distribution with a decentralized or community-controlled one.
- You want to build an application that is permissionless to interact with.
- You want to further openness, freedom of information, and/or personal choice on the internet.
When Not to Use LBRY
- You want to privately distribute data or information. LBRY is designed for publishing and sharing information in an open fashion.
- You want to do illegal things.
Application Basics
You can build many types of apps. Fat apps, short apps, tall apps, skinny apps!
Most end-user applications will use the lbry-sdk as a way of accessing and communicating with the LBRY network. A look at the APIs provided by the SDK will help you understand what facilities the SDK provides.
Some applications do not need to access content available on the network (e.g. a wallet-only app, or a blockchain visualizer). These applications might use lbrycrd, the blockchain daemon, or chainquery, which parses blockchain data into SQL.
Let's look at some specific types of applications and the basic design for each.
Web Applications
Full Web Applications
By full web application, we mean a centrally-hosted web application that uses most or all of the suite of capabilities the LBRY protocol provides.
- Pick your favorite language and stack and do your typical setup to get a "Hello World" application running.
- Install lbry-sdk. (Docker images? Other convenient ways of doing this?)
- Bridging basics.
- See SDK Basics
Blockchain Applications
- Might not need SDK
- Just use chainquery/lbrycrd
Other Web Applications
- Do these exist?
Desktop Applications
Electron Apps
- Use electron-starter kit
- (Explain basic development)
Other Applications
- You can use whatever tooling you want
- Use the SDK (see SDK Basics)
Mobile Applications
Android Applications
- (Whatever magic you have to do to get a daemon running on Android.)
iOS Applications
We do not currently have tooling available to build LBRY apps on iOS.
Application Tooling
SDK
Talk about using SDK, docs, etc.
