The journey begins with assembling the right team. At the core of your backend development effort is at least one backend developer, but the team’s size should align with the project’s scope and timeline.
Flexibility is key here, as you can start with one or two developers and scale up as the project grows. This adaptability allows you to manage resources efficiently and maintain project momentum.
Choosing the Backend Tech Stack
The heart of your backend development lies in the technology stack you choose. This stack defines the tools and infrastructure that power your app’s server, database, and APIs. The selection process involves key decisions, such as:
- Programming Language: This is the foundation of your backend code. Options may include TypeScript, Python, Java, Ruby, and PHP.
- Architecture: Decide whether to opt for a monolithic, modular monolithic, microservices, or serverless architecture.
- Infrastructure: Select the platform where your backend development will operate, such as AWS, Azure, or others.
- Database: Choose between SQL, NoSQL databases, or a combination of different database types to store your data.
- Type of API: Determine the API type, whether it’s JSON, REST, GraphQL, XML, or another format.
For instance: your custom backend development technology stack might include TypeScript as the programming language, a hexagonal monolith architecture, PostgreSQL as the database, and infrastructure hosted on AWS Elastic Beanstalk with AWS RDS.
The choice depends on your project’s unique requirements and your development team’s expertise.
Development & QA
With the tech stack in place, it’s time to kickstart development. This can run concurrently with frontend app development, although initiating backend development a bit earlier can be advantageous.
Early backend development work ensures that crucial features are ready when needed by the frontend developers, preventing bottlenecks in the project timeline.
Backend development operates based on “tasks.” Each task represents a piece of functionality required to make your backend development fully operational.
These tasks come with detailed requirements and acceptance criteria, which help guide developers throughout the process.
Typically, each task involves three key steps:
- Writing Automated Tests: Ensuring the reliability and functionality of the code.
- Modifying Server Infrastructure: Adapting the server to accommodate the new feature or functionality.
- Adding the Code: Implementing the code that brings the feature to life.
Once a developer completes a task, the code undergoes a rigorous code review process by other team members. This practice ensures the code’s quality, adherence to standards, and helps catch any potential issues. Upon approval, the code is merged into the main codebase, and the updated app version is deployed on the server.
Afterwards, a dedicated tester then steps in to ensure that the new functionality works flawlessly. The task is marked as complete with successful testing, and the frontend app can seamlessly utilize the newly added feature.
With each completed task, your backend development grows, and your mobile app takes shape. It’s an interactive process where new features are added and existing ones are refined. Eventually, your app is ready to take its final form and move closer to release.
