nostr-typedef

nostr-typedef provides domain-specific type definitions (and useful doc comments) that are often needed to develop Nostr application with TypeScript. It doesn't contain any implementations, but contains only type definitions. Therefore, it doesn't affect the bundle size of your application at all.

Installation

For example, if your product is a library and some applications may depend on it, the dependency must be declared in dependencies field. In short, -S option is required.

npm install -S nostr-typedef

If not, that is, if your application is not depended on anything else, you can put the dependency in devDependencies field.

npm install -D nostr-typedef

Example

import type * as Nostr from "nostr-typedef";

// OK. No type errors.
const message: Nostr.ToRelayMessage.REQ = ["REQ", "subId", { kinds: [0] }];

// NG. Required fields are missed so a type error occurs.
const event: Nostr.Event = {};
