What does an Angular 2 developer do?
An angular 2 developer builds interactive web applications using the component-based architecture of the Angular framework and TypeScript. This role focuses on creating modular user interfaces where distinct components manage their own logic and view templates. The developer writes code that separates presentation layers from business logic to maintain clean and testable application structures. They use the Angular command line interface to compile, lint, and verify the integrity of the codebase before deployment.
- Authors reusable UI components by defining metadata with the @Component decorator and managing associated HTML templates and style sheets. This process involves structuring the application into small, self-contained units that handle specific parts of the user interface. The developer ensures these components communicate effectively through input and output properties to create a cohesive user experience without tight coupling between different parts of the app.
- Implements application business logic within injectable services and integrates them with components to fetch or manipulate data. This work often includes using the HttpClient module to send requests to backend servers and process the returned JSON responses. The developer structures these services to keep component classes lean and focused solely on view-related tasks while the services handle data retrieval and state management responsibilities.
- Writes automated unit tests for components and services using the TestBed utility to create isolated testing environments. These tests verify that individual parts of the application function correctly in isolation from the rest of the system. The developer configures mock dependencies and simulates HTTP interactions to ensure the code behaves as expected under various conditions without relying on live external APIs during the testing phase.
- Uses Angular CLI commands such as ng build and ng lint to compile source code into optimized bundles and enforce coding standards. This workflow ensures the final application artifacts are free of syntax errors and follow consistent naming conventions across the project. The developer runs these tools regularly to catch potential issues early in the development cycle and maintain high code quality throughout the lifecycle of the software.
How to hire an Angular 2 developer on Upwork
Step 1: Post a job
Define your project requirements clearly to attract qualified candidates who specialize in component-based web applications. Use the Job Post Generator powered by Umaโข, Upwork's Mindful AI to draft a precise description from a few sentences about your needs. You can write a new post, update a saved draft, or reuse an existing post to save time.
- Specify that the freelancer must build user interfaces using Angular components defined with @Component and managed templates.
- Request experience with TypeScript and the Angular CLI toolchain for compiling apps and running linting checks.
- Ask for examples of automated unit tests written with TestBed to verify component and service logic.
Step 2: Evaluate candidates
Review portfolios for evidence of clean, testable code structures and adherence to Angular style conventions. Uma can run instant video interviews and build shortlists with side-by-side comparisons to help you assess technical fit quickly.
- Look for working application code that separates UI concerns in components from business logic in services.
- Check for linted and built artifacts produced by ng build to confirm familiarity with standard workflow commands.
- Verify that past projects include documented test scripts and configs as part of the Angular workspace.
Step 3: Interview your top choices
Discuss specific technical approaches to ensure the candidate understands your architecture and testing standards. Schedule and conduct interviews within Upwork Messages to receive an immediate transcript and summary after each session.
- Ask how they configure or mock HTTP interactions in tests when application logic uses HttpClient.
- Discuss their process for creating isolated unit test environments with TestBed for complex components.
- Review their method for maintaining code quality through consistent naming and directory structures.
Step 4: Agree on scope and begin work
Set clear milestones for delivering working Angular application code and corresponding unit tests. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.
- Define deliverables such as compiled dist/ folders and passing unit test results for each milestone.
- Require the freelancer to run ng lint and ng test before submitting any code for review.
- Establish a schedule for integrating new components and services into the existing codebase.
