Proton Drive SDK

Proton Drive SDK is Proton’s dedicated SDK repository intended to provide reusable client libraries for integrating Proton Drive capabilities into other applications, with an initial focus on a JavaScript SDK and plans for a C# SDK. The repository is explicitly labeled as a work in progress and notes that it is not ready for use yet, which signals that public APIs and stability guarantees should not be assumed at this stage. Its implementation is predominantly TypeScript, which is well-suited for producing strongly typed JavaScript libraries that can be consumed across modern web and Node.js environments. By centralizing shared SDK logic in a single repo, Proton can standardize how third-party or internal clients interact with Proton Drive’s protocols and behaviors, reducing duplication and improving consistency across platforms over time.
