Build Status

A Database Modeler for Node; designed to help you produce easy-to-read, maintainable code.

The goal of this project is not to be everything to everyone. It is not meant to solve every possible edge case. Instead, it is focused on the most common use cases for data-driven applications. That being said, take a gander at the Documentation to see if sequel will fit your application's needs.

Sequel currently works with the following databases:


Add to your application via npm:

npm install sequel --save

This will install sequel and add it to your application's package.json file.

Sequel does not have a database driver as a dependency, so you must install one separately from sequel.

If you are using MySQL, and have not already installed the mysql package, you can install it with the following:

npm install mysql --save

If you are using SQLite, and have not already installed the sqlite3 package, you can install it with the following:

npm install sqlite3 --save


There are a number of ways you can contribute:

  • Improve or correct the documentation - All the documentation is in this file. If you see a mistake, or think something should be clarified or expanded upon, please submit a pull request
  • Report a bug - Please review existing issues before submitting a new one; to avoid duplicates. If you can't find an issue that relates to the bug you've found, please create a new one.
  • Request a feature - Again, please review the existing issues before posting a feature request. If you can't find an existing one that covers your feature idea, please create a new one.
  • Fix a bug - Have a look at the existing issues for the project. If there's a bug in there that you'd like to tackle, please feel free to do so. I would ask that when fixing a bug, that you first create a failing test that proves the bug. Then to fix the bug, make the test pass. This should hopefully ensure that the bug never creeps into the project again. After you've done all that, you can submit a pull request with your changes.

Before you contribute code, please read through at least some of the source code for the project. I would appreciate it if any pull requests for source code changes follow the coding style of the rest of the project.

Now if you're still interested, you'll need to get your local environment configured.

Configure Local Environment

Step 1: Get the Code

First, you'll need to pull down the code from GitHub:

git clone

Step 2: Install Dependencies

Second, you'll need to install the project dependencies as well as the dev dependencies. To do this, simply run the following from the directory you created in step 1:

npm install

Step 3: Set Up Databases

Now, you'll need to set up local test databases for each database driver:

    mysql: {
        host: 'localhost',
        port: 3306,
        user: 'sequel_test',
        password: 'password',
        database: 'sequel_test',
        driver: 'mysql'
    sqlite: {
        filename: ':memory:',
        driver: 'sqlite'

These database credentials are located at test/config/database.js

Running Tests

To run all tests:

npm test

To run all MySQL tests:

grunt test:mysql

To run all SQLite tests:

grunt test:sqlite

If you don't have grunt-cli installed globally, you can run tests with grunt like this instead:

./node_modules/.bin/grunt test:mysql

The above should be run from within the sequel project directory.
