You also need a Node.js project you can use your own or download this sample URL shortener application. This tutorial uses v16.2.0 and 1.56.2, respectively. Setting up a project for Node.js debugging is not particularly difficult, and this tutorial will help you get it right on the first try! Prerequisitesīefore beginning, ensure the most recent versions of both Node.js and Visual Studio Code are installed. You can also evaluate expressions in the editor and step through the code to drill into the problematic parts. When beginning a debugging session, you must inspect the call stack and any scoped variables in their current state. Its built-in debugger can debug any application that targets the Node.js runtime, even if the source code for the application is a language that transpiles to JavaScript, such as TypeScript. The Visual Studio Code editor has all the tools to debug Node.js applications effectively.
How to debug Node.js apps in Visual Studio Code I'm currently working on my own products and teaching programming via my website freshman.tech. For example, for query logging the first parameter is the raw query and the second (hidden by default) is the Sequelize object.Ĭommon useful values for options.Ayooluwa Isaiah Follow I'm a software developer from Nigeria with a keen interest in web technologies, security, and performance. The default value is console.log and when using that only the first log parameter of log function call is displayed. The options.logging option can be used to customize this behavior, by defining the function that gets executed every time Sequelize would log something. Logging īy default, Sequelize will log to console every SQL query it performs. If you are starting a project from scratch, and your database is still empty, Sequelize can be used since the beginning in order to automate the creation of every table in your database.Īlso, if you want to use Sequelize to connect to a database that is already filled with tables and data, that works as well! Sequelize has got you covered in both cases.
To experiment with the other dialects, which are harder to setup locally, you can use the Sequelize SSCCE GitHub repository, which allows you to run code on all supported dialects directly from GitHub, for free, without any setup! New databases versus existing databases
