I've been reading the excellent book Growing Object-Oriented Software, Guided By Tests and there's so much that resonated with me about starting work on a new project.

I first wrote this post in 2020 after spending several weeks containerising a legacy application I hadn't built and didn't fully understand. The experience was mostly archaeology — reading old config files, tracing hardcoded paths, figuring out what half a dozen processes actually did before touching anything. By the time I had a working Docker image, I'd earned it.

I'm updating it now because the journey has changed, and I think it's worth being honest about how.

What is it?​

JSON Web Token (JWT) is a compact, URL-safe means of representing claims to be transferred between two parties. The claims in a JWT are encoded as a JSON object that is used as the payload of a JSON Web Signature (JWS) structure or as the plaintext of a JSON Web Encryption (JWE) structure, enabling the claims to be digitally signed or integrity protected with a Message Authentication Code (MAC) and/or encrypted.

JSON Web Tokens are an open, industry-standard RFC 7519 method for representing claims securely between two parties. See here: https://jwt.io
