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
./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
