3.0.0 - TypeScript, Testing, and Modernization

[Mosnar]

To Do

• Replace API Gateway with Lambda URLs
• Update docs
• Validate use of settings.yml file - is there a better approach? (see notes)
• Update TLS usage
• Add error cache TTL

Bugs

• AVIF generation is too slow
• Finish testing inputValueProcessor
• Should requested dimensions greater than hard-limit max be capped or rejected? (Currently rejected)

Notes

• serverless deprecates the usage of settings.yml, and promotes usage of env files. Would you considering going for the latter option? I can assist maybe if you're ok? (See Modernize serverless-sharp #121)
• I see there is some Makefile and stuff. But the sharp layer for Lambda doesn't really require any building I think (See Modernize serverless-sharp #121)
• TLSv1 <-- still uses this protocol. AWS seems to already recommend 'TLSv1.2_2021' (See Modernize serverless-sharp #121)

Done

• Refactor logging
• Refactor dataflow to make use of middleware
• Refactor exception handling
• Add tests for expected output image sizes (ImageRequest and ImageProcessor)
• Refactor input value parser
• Fix Types & add definitions
• Fix/improve tests
• Improve linting and code style
• Update Sharp to 0.31.x
• Implement bundler for ESM & TS
• Convert to TypeScript
• Update Serverless Framework
• Update Imgix schema
• Add Dockerfiles for building/updating Sharp
