PouchORM

PouchORM adds typed models and named collections to PouchDB. It provides query and write helpers, optional class validation, change hooks, and synchronization management while keeping the underlying PouchDB database available.

Read the documentation or open the API reference.

Installation

Install PouchORM and its PouchDB peer dependency:

npm install pouchorm pouchdb

Install class-validator only when the application uses validation:

npm install class-validator

PouchORM 5 requires Node.js 20 or newer when used in Node. It is published as CommonJS with TypeScript declarations.

Quick start

Define a model and give its collection a stable name:

import { IModel, PouchCollection } from "pouchorm";

interface Person extends IModel {
  name: string;
  age: number;
}

class People extends PouchCollection<Person> {
  constructor(database = "app-data") {
    super({ database, collection: "people" });
  }

  async beforeInit(): Promise<void> {
    await this.addIndex(["age"], "people-by-age");
  }
}

const people = new People();

Create, query, update, and remove documents:

const ada = await people.upsert({
  name: "Ada Lovelace",
  age: 36,
});

const adults = await people.find(
  { age: { $gte: 18 } },
  { sort: [{ age: "desc" }] },
);

const updatedAda = await people.upsert({ ...ada, age: 37 });
await people.remove(updatedAda);

The collection value is stored in $collectionType on every document. Keep it stable across builds and releases; production minification must not determine persisted collection identity.
