Introduction #
express-sequelize-ts is a TypeScript-based boilerplate that enables the creation of web applications using the Express framework and Sequelize ORM.
I developed this boilerplate to assist with the development of some legacy node.js services in my workplace.
I intended to create a boilerplate that could be utilized in various scenarios 🧑💻.
As a developer, I hope this boilerplate proves to be helpful to someone like myself 🥸.
Technology Stacks #
- Express for handling HTTP requests and responses
- Sequelize ORM for interacting with a database
- TypeScript for strong typing and better code organization
- Docker for containerization to keep the development environment consistent
- TypeStack for building decorator based applications
Development Features #
- Jest for unit and integration testing
- ESLint for linting
- Prettier for code formatting
- JWT authentication for secure access to the API
- A Layered architecture (Controller, Service, Repository, Model).
- Data Transfer Object (DTO) for data validation
- Dependency injection for better code organization
- Swagger for API documentation
Challenges and Solutions #
While developing express services with JavaScript, I often faced issues with type safety and code organization 🤔.
To minimize the time spent on these problems and concentrate on the business logic, I decided to use TypeScript and Decorator-based programming as solutions.
Although options like NestJS or TSOA exist, I chose TypeStack to build decorator-based applications to avoid the risk of resource consumption and a learning curve.
If you’re curious about why I chose TypeStack, please refer to my post
here 🥸.
Conclusion #
It could not be the perfect solution for everyone, but I hope this boilerplate will assist you in developing a web application with TypeScript, Express, and Sequelize 🙏.
