Using APIs in Web App Development
An API is a platform that allows different pieces of software, or applications, to communicate with one another. The term is used broadly in programming languages, the web, operating systems, and more. Developers use APIs for various purposes all over the technology industry; some examples include:
- Facebook's Graph API
- Google Maps APIs
- Twitter APIs
When it comes down to using an API within engineering projects (such as within Web development), there are several options for both front-end and back-end engineers alike. Some common uses may be seen below:
Front End Usage Examples -Creating user interfaces based on data provided by third-party resources like social media accounts -Completing authentication processes via OAuth -Pulling in dynamic data to make websites more interactive
Back End Usage Examples -Asynchronous request handling for faster load times -Scraping web pages or collecting large amounts of data from third-party sources into a database. -Powering other APIs used within your project, such as online storage, user authentication tools, etc. Developers can use APIs to tackle these problems using different programming languages depending on the API itself; some examples are below:
Programming Language Examples
- Python (using JSON requests)
- PHP(using SOAP services)
There are several benefits to using APIs when it comes to engineering projects.
Benefits of Using APIs
- Code simplification/reduction: Developers can avoid writing code that would otherwise need to be written to access the data or perform specific tasks within a project by leveraging an API instead. This is especially useful for engineers with limited time and resources at their disposal. They will require fewer development hours due to how much work is done on behalf of their applications already via third-party sources.
- Time efficiency: Developing software applications from scratch requires many hours of research and testing before production launch; however, this process can be significantly shortened if developers can utilize pre-written toolsets available through other company's existing offerings.
- Scalability: APIs usually provide a way for developers to implement future changes and updates without overhauling or rewriting their entire project. This is especially useful if users are dependent on the API's service. They will only need support from the company that offers it to maintain compatibility with any new releases of software/updates.
- Security: Developers can also utilize APIs to make their applications more secure by using specific access keys or authentication processes (OAuth) that require user information before providing the requested data.
- Code reusability: APIs often provide some degree of code customization that can be reused within another project. This is especially useful for engineers looking to save time and resources by using pre-existing toolsets already provided through an API instead of pushing their solution from scratch.
