Description

anpan is a lightweight Redis Object Mapper (OM) library built for the Bun runtime. Bun is an up-and-coming runtime environment for Javascript and Typescript that replaces Node.js. Bun’s v1.0 was released on September 8th, 2023, and has since demonstrated that they are 4x faster than Node.js and 2x faster than Deno. Since their release, many developers, like those working with a Redis database, are seeking to run their code in Bun for its speed and efficiency. Unfortunately, no Redis-specific library currently runs in the Bun runtime environment. anpan is a Redis OM that bridges the gap for developers working in Bun with a Redis database. anpan works to abstract away hard-to-understand and write syntax, that, when paired with the anpan webpage, helps even a new user learn Redis right away. anpan brings the familiarity of other databases and libraries, like MongoDB and Mongoose, allowing other NoSQL database users easy access and navigation.

Getting Started

Be sure that you have the Bun runtime installed and configured.

Quick Start

In your application, install the package from the NPM module.

bun i @breadisbuns/anpan

Next, require in the anpan module into your codebase.

const { Schema, Repository } = require('@breadisbuns/anpan');

Connect to your Database

Open a connection by requiring in createClient from Redis with the Redis cloud link found in your Redis dashboard, and using the connect method from Redis.

const { createClient } = require('redis');

const { client } = createClient({
  password: 'YOUR PASSWORD HERE',
  socket: {
    host: 'LINK TO CLOUD',
    port: 12179,
  },
});

await client.connect().then(console.log('Connected to Redis'));

Define Your Schema

Now, you can define your schema with the Schema method as shown below or by utilizing the schema generator on the anpan webpage:

const bakerySchema = new Schema('bakery', {
  name: { type: 'string', isRequired: true },
  owner: { type: 'string', isRequired: true },
  dateCreated: { type: 'date' },
  bakeryNum: { type: 'number' },
  location: { type: 'point' },
  bunsOffered: { type: 'string[]' },
});

Valid Datatypes include:

• boolean
• date
• number
• number[]
• point
• string
• string[]
• text

Create Your Repository

Set up a repository by invoking the Respository method with your schema name and client:

const theBakeries = new Repository(bakerySchema, client);

Add to Your Repository

You can now add to the repository by creating entities with your data as outlined in your schema:

const anpanBun = {
  name: 'Buns Unlimited',
  owner: 'May',
  dateCreated: new Date(2023, 1, 14),
  bakeryNum: 1,
  location: { longitude: 1, latitude: 1 },
  bunsOffered: ['Hotcross', 'Hotdog', 'Steamed'],
};

const mayBakery = await theBakeries.save(anpanBun); //adds entity to Redis database

Make a Query

Now, you can search and find items in your model. For example, if you wanted to look at the buns offered at May's Buns Unlimited bakery, you can fetch by ULID:

//---Targeting a ULID---
const mayULID = mayBakery.entityKeyName;
console.log(mayULID); //displays ULID in your console to fetch

//---Fetching w/ULID---
let fetchMay = await theBakeries.fetch(mayULID);
console.log(fetchMay); //will log fetched mayBakery

Congratulations! You have successfully imported anpan, connected to Redis client, created a schema and a repository, added an entitiy to your Redis database, and fetched May's bakery. Explore the rest of the README.md for more detailed instructions on how to use anpan.

Query

All queries in anpan are performed using repositories. All query methods are listed below:

• getAllEntities

const allBakeries = await theBakeries.getAllEntities();
console.log(allBakeries); //Will log all stored bakeries!

• getByString

const findString = await theBakeries.getByString('Kevin');
console.log(findString); //Will log all bakeries containing queried string

• getByNumber

const findNumber = await theBakeries.getByNumber(1);
console.log(findNumber); //Will log all bakeries containing queried number

Additional Methods

Additional features and methods include:

• update with save()

//---Update with save()---
fetchMay.bunsOffered.push('Melonpan');
fetchMay = await theBakeries.save(fetchMay);
console.log(fetchMay); //Will log with additional bun offered

• remove with ULID

//---Remove w/ULID---
const dillonULID = dillonBakery.entityKeyName;
const deleteDillon = await theBakeries.remove(dillonULID);
console.log(deleteDillon); //Will log undefined

• expire with ULID

//---Expire w/ULID---
const kellsyULID = kellsyBakery.entityKeyName;
const expireKellsy = await theBakeries.expire(kellsyULID, 10); //Will show countdown in RedisInsight, logs undefined after expiration
