The widely used dating software Tinder enables users to browse the profiles of possible matches and, if both parties swipe right, connect with them. Although the user interface and functionalities of the app are what people find so tempting, the technology that underpins it is equally outstanding. We will examine the backend, database, and number of lines of code used by Tinder in this article. Background
Node.js, Redis, and Elasticsearch are among the technologies used to build Tinder’s backend. A well-liked JavaScript runtime called Node.js is excellent for creating scalable and fast apps. An open-source, in-memory data structure store called Redis is employed for session management and caching. A search engine called Elasticsearch is used for indexing and searching through vast volumes of data.
A highly scalable and reliable system, Tinder’s backend architecture is built to handle millions of queries each day. The backend servers’ workload is lessened by the usage of Redis for caching and session management, and Elasticsearch for quick and effective user data searching. The database
Cassandra is a NoSQL database that Tinder utilizes to store user information. A distributed database with excellent availability and scalability is called Cassandra. Many popular websites and applications utilize it because it can handle massive volumes of data.
Cassandra is a great option for Tinder’s database since it makes easy scaling possible as the user base expands. A trustworthy option for a worldwide app like Tinder, it is also built to manage many data centers.
Although Tinder’s precise number of lines of code is not known, it is assumed to be somewhere between 50,000 and 100,000 lines. Comparatively speaking to other widely used apps and websites, this has a minimal amount of code.
The tiny codebase is evidence of Tinder’s architecture’s effectiveness and simplicity. Additionally, it makes it simpler to update and manage the app, which is crucial for keeping up with the ever changing online dating industry.
To sum up, Tinder employs Node.js, Redis, and Elasticsearch in combination with Cassandra for its database and has anywhere between 50,000 and 100,000 lines of code. These technologies enable the creation of a highly dependable and scalable system that can manage millions of requests each day. Tinder’s architecture is effective and straightforward, as evidenced by the tiny codebase, which makes it simpler to maintain and improve the app over time.
