  • querySrv errors when connecting to MongoDB Atlas
    3 projects | dev.to | 29 Feb 2024
    If your application uses MongoDB's Node.js driver or Mongoose ODM, occasionally you may observe errors such as querySrv ECONNREFUSED _mongodb._tcp.cluster0.abcde.mongodb.net or Error: querySrv ETIMEOUT _mongodb._tcp.cluster0.abcde.mongodb.net being thrown. The MongoDB Atlas documentation outlines several methods to troubleshoot connection issues, including how to handle "Connection Refused using SRV Connection String" scenarios, but why does this happen in the first place?

    After importing the mongoose module, use the [mongoose.connect()](https://mongoosejs.com/docs/api/mongoose.html#mongoose_Mongoose-connect) function to connect to the database. The first argument is the connection string, and the second argument is an object that contains the options, which are used to configure the connection. The above code logs the message, MongoDB connection is established successfully! 🎉, once the connection is successful.

    Helmet helps “sanitise” the input, which might not have come from the UI directly. Mongoose is what is known as an Object Document Modelling (ODM), which defines a structure (schema) for the stored data, making it easier to manage in Express. These additions have been omitted from our example stack purely to simplify the tutorial and focus on the fundamental tiers and interfaces.

    You can check libraries in many ways. A good starting point is probably the package manager you are using in your application. In the case of Node.js, it is probably NPM. For example, if you want to check the mongoose library and look at some data points, you can head over to https://www.npmjs.com/package/mongoose.

  • How to Build & Deploy Scalable Microservices with NodeJS, TypeScript and Docker || A Comprehesive Guide
    13 projects | dev.to | 25 Jan 2024
    Our orders microservice will have its own set of teachnologies just like we earlier plotted that is mysql database and sequelize orm. MySQL is an open-source relational database management system (RDBMS) that is widely used for building web applications and managing data. It is a popular choice for many developers and organizations due to its performance, reliability, and ease of use. Sequelize is a popular Object-Relational Mapping (ORM) library for Node.js. It provides a way to interact with relational databases like MySQL, PostgreSQL, SQLite, and MSSQL using JavaScript or TypeScript. It simplifies database operations by allowing developers to use JavaScript objects to represent database tables and records, instead of writing raw SQL queries. In this microservice, we will use it to query our MySQL database.

    I mean I am not really a pro be dev. But there is such tools as https://sequelize.org/ and it can work with different DBs, if your current DB doesn't support this you can always switch to that one which do. Switching to another language doesn't really do much.
