typescript and mongoose code example

Example 1: typescript generic mongoose example

import { Schema, model, Document, Model } from 'mongoose';

declare interface IContact extends Document{
    name: string;
    email: string;
    phone?: string;
    message?: string;
    course_enquiry?: string;
    creation_date: Date;
}

export interface ContactModel extends Model<IContact> {};

export class Contact {

    private _model: Model<IContact>;

    constructor() {
        const schema =  new Schema({
            name: { type: String, required: true },
            email: { type: String, required: true },
            phone: { type: String },
            message: { type: String },
            course_enquiry: { type: String },
            creation_date: { type: Date, default: Date.now }
        });

        this._model = model<IContact>('User', schema);
    }

    public get model(): Model<IContact> {
        return this._model
    }
}Copied!

Example 2: typescript mongoose required functions

required: function customRequire(this: TheModelInterface) {}

Example 3: mongoose with typescript

import mongoose from 'mongoose'
import consola from 'consola'
import q from 'q'

export const mongooseConnection = (): void => {
	mongoose.Promise = q.Promise

	mongoose.connect(process.env.MONGO_URI, {
		minPoolSize: 1,
		maxPoolSize: 20,
		compression: { compressors: ['zlib'] },
		useUnifiedTopology: true,
		useNewUrlParser: true,
		useFindAndModify: false,
		socketTimeoutMS: 60000,
		serverSelectionTimeoutMS: 60000,
		loggerLevel: 'error'
	})

	mongoose.connection.on('connecting', () => consola.info('database connecting'))
	mongoose.connection.on('connected', () => consola.success('database connected'))
	mongoose.connection.on('disconnecting', () => consola.info('database disconnecting'))
	mongoose.connection.on('disconnected', () => consola.info('database disconnected'))
	mongoose.connection.on('error', () => consola.error('database error'))
}
