@orbitdb/set-db

Set database type for OrbitDB.


Installation

``
$ pnpm add @orbitdb/set-db
`

Introduction

As Set database is like a Feed, but each value can only be present once. Works for primitive types as well as more complex objects.

Examples

A simple example with Set:
`ts
import { createOrbitDB } from "@orbitdb/core";
import { registerSet } from "@orbitdb/set-db";

// Register set database type. IMPORTANT - must call before creating orbit instance !
registerSet();

const orbitdb = await createOrbitDB({ ipfs })

const db = await orbitdb.open({ type: "set" });

await db.add(1);
await db.add(2);

const all = await db.all(); // [1, 2]

await db.add(1);
await db.all() // Yay !! Still [1, 2]
`

As more complex example with object types:
`ts
import { createOrbitDB } from "@orbitdb/core";
import { registerSet } from "@orbitdb/set-db";

// Register set database type. IMPORTANT - must call before creating orbit instance !
registerSet();

const orbit = await createOrbitDB({ ipfs })

const db = await orbitdb.open({ type: "set" });

await db.add({a: 1});
await db.add({a: 2});

const all = await db.all(); // [{a: 1}, {a: 2}]

await db.add({a: 1});
await db.all() // Yay !! Still [{a: 1}, {a: 2}]
