mongo-base-crud

Lib to simple handler singleton classes em typescript

Install

npm i mongo-base-crud

Usage

Create .env file with

MONGO_URL="mongodb://admin:admin@localhost:27017"
MONGO_DB=test
MONGO_PREFIX_NAME=test_

MONGO_URL full url with a mongo connection MONGO_DB database name MONGO_PREFIX_NAME prefix name to any database that will be created. To keep simple to deal with enviroment or whitelabel projects

Using to create repository class

import { Singleton } from "typescript-singleton";
import BaseCrud from "mongo-base-crud";

export class MyClassExample extends BaseCrud<{id:string, name:string}> {
  public static instance(): MyClassExample {
    return Singleton.getInstance<MyClassExample>(`MyClassExample`, MyClassExample);
  }
  constructor() {
    super("my_collection", "my_database", { clinicAlias: true, unitAlias: true });
  }
}

Using to create repository function to get generic BaseCrud to deal with a collection

function getCrud(){
  const genericCrud:BaseCrud<MyDTO> = BaseCrud<MyDTO>.getInstance("collectionName", "dbName", { type: 1 });
  return genericCrud;
}
getCrud().find().then(console.log)

Another examples

// Example to add an object

const newObj = { id: "1", name: "John Doe" };
MyClassExample.instance().add(newObj).then(result => {
  console.log("Object added:", result);
}).catch(error => {
  console.error("Error adding object:", error);
});

//if you do not pass id, it will auto created

const newObj = { name: "John Doe" };
MyClassExample.instance().save()

// Example to find objects
MyClassExample.instance().find().then(result => {
  console.log("Objects found:", result);
}).catch(error => {
  console.error("Error finding objects:", error);
});

// Example to delete an object
const objectId = "1";
MyClassExample.instance().delete(objectId).then(result => {
  console.log("Object deleted:", result);
}).catch(error => {
  console.error("Error deleting object:", error);
});

MyClassExample.instance().find().then(result=>{console.log(result)});

Find

Find params

filter

Optional, object to find exactly filter. If you do not pass, no filter will be used and will be get all data

select

Data to return just some params of full object data fields

ex: {id:true, name:true},

skip

ex: 0

for pagination, start in first, optional, default 0

limit

ex: 10

for pagination, get just 10 or less, optional, default 10, get all

orderBy

ex: "name"

order by name, optional, default undefined

direction

ex: "asc" or "desc"

optional, default asc if is setted orderBy

searchValue

ex: "ab" to find abajour or ában or foolabicon

search by part of string, optional, default undefined, do not filter

searchFields

ex: ["name"]

the fields that a search will be use to search, optional, no default, if you do not pass, nothing will be search

Find example

export interface MyUserDto{
  id: string,
  name: string,
  cateogry: string,
  birthdate: Date,
  lastname: string,
  active: boolean
}
export async function serviceTofind(active:boolean, category:string, freeQuery?:string):Promise<List<MyUserDto>>{
  const filter: Partial<MyUserDto> = {
    active,
    category
  }
  const resultData:List = MyClassExample.instance().find(
    filter, //filter active and category identical data
    {id:true, name:true}, // return just name and id
    skip = 0, // for pagination, start in first, optional, default 0
    limit = 20, // for pagination, get just 10 or less, optional, default 10, get alll
    orderBy = "name", // order by name, optional, default undefined
    direction = "asc", //optional, default asc if is setted orderBy
    searchValue = freeQuery, //search by part of string, optional, default undefined, do not filter
    searchFields = freeQuery?["name", "lastname"]: undefined // the fields that a search will be use to search, optional, no default, if you do not pass nothing, nothing will be search
  )
  const total:number  = resultData.total;
  const listData:any[] = resultData.data;
  return resultData;
}

Update

 * Updates an existing document in the database.
 * 
 * @param data - An object containing the fields to update and the document's ID.
 *               The object must include an `id` property with the document's ID.
 *               If the object contains an `updatedAt` property, it will be set to the current date.
 * 
 * @returns A promise that resolves to the updated document with its ID.
 * 
 * @throws Will throw an error if the update operation fails.

async update(data: { [key: string]: any; id: string }): Promise<DocumentWithId> {
  if (data.hasOwnProperty("updatedAt")) {
    data.updatedAt = new Date();
  }
  const result = await (await this.dbInterface).update(data);
  return result;
}

Example to update an object

// Example to update an object

const updatedObj = { id: "1", name: "Jane Doe", updatedAt: new Date() };
MyClassExample.instance().update(updatedObj).then(result => {
  console.log("Object updated:", result);
}).catch(error => {
  console.error("Error updating object:", error);
});

// Example to update an object without updatedAt field

const updatedObjWithoutDate = { id: "2", name: "John Smith" };
MyClassExample.instance().update(updatedObjWithoutDate).then(result => {
  console.log("Object updated:", result);
}).catch(error => {
  console.error("Error updating object:", error);
});

Partial update

/**
 * Partially updates an existing document in the database.
 * 
 * @param id - The ID of the document to update.
 * @param data - An object containing the fields to update.
 *               If the object contains an `updatedAt` property, it will be set to the current date.
 * 
 * @returns A promise that resolves to the updated document with its ID.
 * 
 * @throws Will throw an error if the update operation fails.
 */
async partialUpdate(id: string, data: { [key: string]: any }): Promise<DocumentWithId> {
  if (data.hasOwnProperty("updatedAt")) {
    data.updatedAt = new Date();
  }
  const result = await (await this.dbInterface).partialUpdate(id, data);
  return result;
}

Example to partially update an object

// Example to partially update an object

const partialUpdateData = { name: "Jane Doe" };
MyClassExample.instance().partialUpdate("1", partialUpdateData).then(result => {
  console.log("Object partially updated:", result);
}).catch(error => {
  console.error("Error partially updating object:", error);
});

// Example to partially update an object with updatedAt field

const partialUpdateDataWithDate = { name: "John Smith", updatedAt: new Date() };
MyClassExample.instance().partialUpdate("2", partialUpdateDataWithDate).then(result => {
  console.log("Object partially updated:", result);
}).catch(error => {
  console.error("Error partially updating object:", error);
