🧐 About

Elastictype is a easy way to model application data stored in Elasticsearch. It is inspired by mongoose and @nestjs/mongoose and thus includes type casting, validation, query building, hooks and much more. It is written in TypeScript and provides type safety.

🏁 Features

• Type casting
• Validation
• Query building
• Hooks
• Type safety
• Intuitive index declaration via Decorators

🏁 Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

Please make sure you have installed the following tools:

• Node.js - JavaScript runtime environment
• Elasticsearch - Search engine

Installing

Install the package via npm:

npm install @cytex/elastictype --save

or via yarn:

yarn add @cytex/elastictype

🎈 Usage

Basic usage

import {
  BaseSchema,
  ElasticField,
  ElasticDataType,
  Index,
  Model,
} from "@cytex/elastictype";

@Index({
  name: "cats", // Name of the index
})
export class Cat extends BaseSchema<Cat> {
  @Prop(ElasticDataType.Keyword)
  public name: string;

  @ElasticField({
    // Type of the field (used for explicit mapping declaration)
    type: ElasticDataType.Integer,
  })
  public age: number;
}

// Create the index and the mapping in Elasticsearch
Cat.syncMapping();

// Create a new cat
const cat = new Cat();
cat.name = "Garfield";
cat.age = 42;

// Save the cat to Elasticsearch
await cat.save();

// Update the cat
await cat.update({ age: 43 });

// Delete the cat
await cat.delete();

// Find all cats
const cats = await Cat.find({ age: 43 });

// Find a cat by id
const cat = await Cat.findById("foo");
