Papai is storage provider intended for Local-first use with support for distrubuted storage implementation.

With ever-growing implementations for different storage options like localStorage, AsyncStorage, level, IndexedDB, WebSQL, Papai makes it possible to use the same interface attached to different storage options, leaving you concerned with building the business side of your applications.

Usage

*For the sake of demonstration, we'll it's being used in a web project

Installation

Install papai and the storage option of your choice

• Install papai

  # include papai in the project
  yarn add papai

• Installing storage option of choice - in the case of a project, we'll use localStorage

Actual use

Instantiate the store through the papai collection provider

import { getStore } from "papai/collection";
import type { Document, Collection } from "papai/collection";
import { ItemStorageCollection, asyncAdapter } from "papai/stores/collection";

import { v4 as uuidV4 } from "uuid";

/**
 * Id generator for new documents created.
 * Alternatively, you can use anyother id generating
 * functions that suits your need: (e.g. nanoid, react-native-uuid etc.)
 */
const generateId = () => uuidV4() as string;

const STORAGE_NAME = `@DEMO_DATABASE`; // database name

// function to define how to refernce a collection and document respectively in the storage
const refenceCollection = (r: Collection.Ref) =>
	`${STORAGE_NAME}/${r.collectionId}`;
const referenceDocument = (r: Document.Ref) =>
	`${STORAGE_NAME}/${r.collectionId}/${r.documentId}`;

// Created a storage instance with `localStorage`
const store = getStore(
	ItemStorageCollection({
		nameReference: STORAGE_NAME,
		store: asyncAdapter(localStorage), // makes local storage useful to `ItemStorage`
		getDocRef: referenceDocument,
		getCollRef: referenceCollection,
	})
);

Use the store in your projects

• Get students collection reference

  import { collection } from "papai/collection";
  
  // Reference to reference (may or may not exist yet)
  // collection is type aware
  const students = collection<{ name: string; course: "science" | "arts" }>(
  	store,
  	"students"
  );

• Add to student collection

  import { addDoc } from "papai/collection";
  
  // add to collection | this is type-safe
  const johnId = await addDoc(students, { name: "John Doe", course: "arts" });
  
  // `johnId` contains id generated by the generateId function

• Read data

  import { doc, getDoc } from "papai/collection";
  
  // read document of id from students collection
  const [_id, data] = await getDoc(doc(students, johnId));

• Update data

  import { doc, updateDoc } from "papai/collection";
  
  // update document for student with id `johnId` | still type-safe
  await updateDoc(doc(students, johnId), { course: "science" });
