pf-3-to-4 v1.0.1

pf-3-to-4

CLI utility to help ease products transitioning to our new major @patternfly/react-core 4.0.0 release.

Goals

• We want to minimize code changes and respect existing code
• We only want to make safe modifications
  • Don't touch code that we aren't sure is PatternFly

redallen rationale

• Most consumers are using JSX
  • When they're using React.createElement or React.cloneElement that introduces unsafe complications

Design

• Use a JSX parser that leaves formatting alone as much as possible
• Add basic ESM import parsing to make sure we're only modifying PatternFly <Button>s

Development

This is what @redallen does to develop a rule: 1. Copy a rule at lib/rules/* 2. Add it to .eslintrc.json 3. Copy a test at test/rules/* 4. Put code into an AST explorer like https://astexplorer.net/ . Add code to "failing" version of test. 5. Write rule targeting specific AST node. Confirm AST node exists in lib/rules/ast-node-types.d.ts. 6. Amend test/test.tsx with code that requires fixing. 7. Develop fixer while testing it with npm run test -- --fix
