To create the database using Sequelize, we can simply run the following command: sequelize db:createĪnd this logs the following: Sequelize CLI Loaded configuration file “config/config.json”. This database is represented against the database keyword in our config.
Now that we have postgres service up and running, we need to create the database first which can subsequently hold our tables. One of the use cases of having the config is to create the database necessary. This config can now be used to perform any and all subsequent interactions with postgres. Since we are running the database locally, the host IP is localhost (127.0.0.1).

The config folder as expected, contains a file called config.json which has the default object that is generated, since we are only worried about the development flow, remove test and production entries from the config.json object which leaves us with the following:Īs you can see from above, we specified the dialect to be postgres and the username and password are the same which were configured in the project setup. Which is essentially our config + empty folder to contain the models, migrations and seeders. Successfully created seeders folder at “/sequelize-setup/seeders”. Successfully created migrations folder at “/sequelize-setup/migrations”. To initialize the project with the CLI, run the following command on Terminal at root of your project: sequelize initĪnd it logs the following: Sequelize CLI Created “config/config.json” Successfully created models folder at “/sequelize-setup/models”. For simplicity, I am going to omit the node_modules/.bin/ prefix and use only the sequelize keyword moving forward with all the commands. We can now utilize the cli which can be found at node_modules/.bin/sequelize.
#DOWNLOAD POSTICO INSTALL#
To install the cli, run the following command: npm install -save sequelize-cli To have the necessary files in place, we can either create these folders manually or a better alternative is to simply use the Sequelize CLI to do so.
Migrations - files containing any and all changes that we make to our tables.Config - configuration necessary to run Sequelize.To be able to set up a Sequelize based project and run it successfully, we will need the following:
#DOWNLOAD POSTICO DOWNLOAD#
We will also be using Postico to provide the GUI for the database so download it here. The role that we just setup in the Postgres DB is the username and password that can be used to connect to any databased in the future with Superuser privileges. Once you have answered all the questions, you will see the basic package.json file generated at the root
Answer the questions that are prompted regarding your projects description. To do so, create a your project folder sequelize-setup and then run the following command at the root of the folder. To do this, let us first create a blank NodeJS project. In our example, we are going to focus solely on Sequelize and not have any dependency on the NodeJS framework(s). In most of the applications, you would be creating (or use a pre existing) API application which is built using a NodeJS based framework such as ExpressJS or NextJS. Their documentation is pretty exhaustive with a list of all the features that they provide, in this article we will see a very coherent way of setting up a project with Sequelize and how we can apply changes to our models based on our evolving application(s). However, just like any tool or framework, there are some issues which we run into when we first get started with Sequelize. Sequelize is possibly one of the best NodeJS ORM library that is available for developers to use.
