NestJS Couchbase

A Couchbase module for NestJS

Installation

$ npm i @scalio-oss/nest-couchbase couchbase

Usage

@scalio-oss/nest-couchbase uses couchbase as a data provider and the Repository pattern to handle all items (documents) related operations.

First, let’s create an Entity:

import { Entity } from '@scalio-oss/nest-couchbase';
@Entity('cats')
export class Cat {
  name: string;
}

Where cats is the Couchbase bucket name (optional).

Then, we need to import CouchbaseModule in our root AppModule:

import { Module } from '@nestjs/common';
import { CouchbaseModule } from '@scalio-oss/nest-couchbase';
@Module({
  imports: [
    CouchbaseModule.forRoot({
      url: 'couchbase://127.0.0.1',
      username: 'couchbase',
      password: 'couchbase',
      defaultBucket: {
        name: 'test',
        password: 'password',
      },
      buckets: [
        {
          name: 'another_bucket',
          password: 'another_password',
        },
      ],
    }),
  ],
})
export class AppModule {}

In our CatsModule we need to initiate repository for our Cat entity:

import { Module } from '@nestjs/common';
import { CouchbaseModule } from '@scalio-oss/nest-couchbase';
import { CatsService } from './cats.service';
import { CatsController } from './cats.controller';
import { Cat } from './cat.entity';
@Module({
  imports: [CouchbaseModule.forFeature([Cat])],
  providers: [CatsService],
  controllers: [CatsController],
})
export class CatsModule {}

And here is the usage of the repository in the service:

import { Injectable } from '@nestjs/common';
import { InjectRepository, Repository } from '@scalio-oss/nest-couchbase';
import { Cat } from './cat.entity';
@Injectable()
export class CatsService {
  constructor(
    @InjectRepository(Cat)
    private readonly catsRepository: Repository<Cat>,
  ) {}
  findOne(id: string): Promise<Cat> {
    return this.catsRepository.get(id);
  }
}
