Apps built with TypeScript

TypeScript's value grows with the number of people touching a codebase and the length of time it has to survive. Types catch the class of error that would otherwise surface in production, and, often more importantly for teams here, they document intent. When a codebase is handed between contractors, or maintained by whoever is available rather than whoever wrote it, a typed function signature is the most reliable documentation that exists. Editor autocomplete also flattens the learning curve for developers new to a project, which shortens onboarding when engineering capacity turns over. The cost is a build step and some initial friction, which is why quick prototypes often start in plain JavaScript and migrate. It is now the default for serious frontend work and increasingly for Node backends. Browse the products built with TypeScript below.
