@fusectore/actions-yaml v1.0.2

actions-yaml

Summary

Prototype for porting the Actions workflow parser and template expansion library to TypeScript.

Key aspects:

• Portability
  • Enables converging on one implementation. JavaScript can be consumed directly within the web UI. Services can consume as a container (REST interface). Also supports command-line interface.
• Safe to run on servers
  • Memory safeguards are deeply built into expressions and templating libraries
• Schema-driven; generic underlying expressions and templates library
  • Schema-validating reader which can be used to parse/expand other schemas - e.g. action.yml or stack.yml

Folder structure

• ./expressions/
  • Generic expression library
• ./templates/
  • Generic templating library
  • template-reader.ts reads a file
    • reads DOM using ObjectReader interface; convert to TemplateToken; schema validate
  • template-evaluator.ts expands a TemplateToken
    • expands a TemplateToken; schema validates result
• ./workflows/
  • Parses and expands an Actions workflow.yml
