JSON Theme

[alexbchr]

Convert Theme structure from Typescript to JSON format.

This has 2 main advantages:

• Validate theme values and structure at build time.
• Possibility to extract Theme (JSON files), outside the codebase (such as in a DB, remote server).

How it works?

We use JSON Schema to validate Theme JSON format.

However, since writing a JSON Schema can be lengthy and has a bit of a learning curve, we use Typescript to generate the JSON Schema. To do so, we use typescript-json-schema.

We also use ajv-cli to validate that JSON Theme files follow the defined shema. These tools are included in the build script to make sure everything will work correctly.

One possible improvement could be to be able to extend themes, a bit like before. For example, the base light theme could contain all theme keys and values, while dark theme could only specify the values it wants to override from the light theme.
