Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

adapter-mongoose-driver

v1.0.1

Published

A library to abstract the mongo database

Readme

MongoDatabase

Este projeto tem por objetivo oferecer uma abstração das configurações de conexão e principais métodos da biblioteca Mongoose.js. Projeto antigo não mais recebendo atualizações.

Instalação

A instalação deste pacote é feita através do NPM

  1. Adicione a referência do repositório privado através do arquivo ./.npmrc do PROJETO.
# ./.npmrc
registry=
always-auth=true

2. Adicione a biblioteca através do **NPM**.
```bash
# npm
npm install adapter-mongoose-driver --save

# yarn
yarn add adapter-mongoose-driver

Utilização

Para utilizar a biblioteca basta importar o módulo e fornecer as variáveis da instância do MongoDB que deseja-se conectar, a saber: host, username, password, database, port e sslKey. Vale lembrar que os parâmetros port e sslKey são opcionais, assumindo os valores 27017 e null respectivamente.

const getConnector = require('adapter-mongoose-driver');
const fs = require('fs');

const host = '127.0.0.1';
const username = 'root';
const password = 'root';
const port = 27017;
const database = 'admin';
let instance = null;

// SSL Key
const sslKey = fs.readFileSync(`${__dirname}/rds-combined-ca-bundle.pem`);

// Without SSL
instance = getConnector(host, username, password, database, port);

// With SSL
instance = getConnector(host, username, password, database, port, ssl);

Methods

getConnection (options = {})

Abre uma conexão com o banco MongoDB, fazendo uso dos parâmetros passados no construtor do módulo, além de permitir a passagem de parâmetros personalizados pelo objeto options.

const getConnector = require('adapter-mongoose-driver');

let instance = null;

// Without SSL
instance = getConnector(host, username, password, database, port);

const conn = await instance.getConnection();

closeConnection (conn)

Fecha uma conexão com a instancia do banco MongoDB.

const getConnector = require('adapter-mongoose-driver');

let instance = null;

// Without SSL
instance = getConnector(host, username, password, database, port);

const conn = await instance.getConnection();
await instance.closeConnection(conn);

getModel (conn, {name, schema, indexes = [], options = {}, virtuals = []})

Cria/Obtem o Model da collections enviada por parâmetro. Caso o model já tenha sido criado, este será reaproveitado

const getConnector = require('adapter-mongoose-driver');

let instance = null;

// Without SSL
instance = getConnector(host, username, password, database, port);

const conn = await instance.getConnection();

const schemaStruct = {
  name: 'topics', // collectionName
  schema: { // collectionStructure (Schema)
    name: {type: String, required: true},
    age: {type: String, required: true},
  },
  options: { // Mongoose Schema Options
    timestamps: true,
    toJSON: {virtuals: true},
    toObject: {virtuals: true},
  },
  indexes: [ // Collection Indexes
    {shortname: 1, learnPathId: 1, sessionId: 1},
  ],
  virtuals: [ // Mongoose Virtual Properties
    {property: 'likes', // Property name
      value: {ref: 'topics_likes', // Property Merge Option
        localField: '_id',
        foreignField: 'topic',
      },
    },
  ],
}

const Model = await instance.getModel(
  conn, schemaStruct
);

const doc = new Model({
    name: 'Talita',
    age: '22',
});

await doc.save();

await instance.closeConnection(conn);

getSchema (conn, {schema, indexes = [], options = {}, virtuals = []})

Cria o Schema dá Collection sem Criar o Model. Utilize este método apenas para usar de referência na construção de outros schemas (Embedded Collection).

const getConnector = require('adapter-mongoose-driver');

let instance = null;

// Without SSL
instance = getConnector(host, username, password, database, port);

const conn = await instance.getConnection();

const schemaStruct = {
  name: 'topics', // collectionName
  schema: { // collectionStructure (Schema)
    name: {type: String, required: true},
    age: {type: String, required: true},
  },
  options: { // Mongoose Schema Options
    timestamps: true,
    toJSON: {virtuals: true},
    toObject: {virtuals: true},
  },
  indexes: [ // Collection Indexes
    {shortname: 1, learnPathId: 1, sessionId: 1},
  ],
  virtuals: [ // Mongoose Virtual Properties
    {property: 'likes', // Property name
      value: {ref: 'topics_likes', // Property Merge Option
        localField: '_id',
        foreignField: 'topic',
      },
    },
  ],
}

const Schema = await instance.createSchema(
  conn, schemaStruct
);

await instance.closeConnection(conn);
