ESLint Rules

This is the base rules for eslint that we can share between projects and then override if we need to on a project basis.

Automatic Conversion notes

64 rules replaced with their ESLint equivalents.

6 ESLint rules behave differently from their TSLint counterparts

• one-var:
  • Variables declared in for loops will no longer be checked.
• camelcase:
  • Leading and trailing underscores (_) in variable names will now be ignored.
• no-underscore-dangle:
  • Leading or trailing underscores (_) on identifiers will now be forbidden.
• no-invalid-this:
  • Functions in methods will no longer be ignored.
• no-unused-expressions:
  • The TSLint optional config "allow-new" is the default ESLint behavior and will no longer be ignored.
• eqeqeq:
  • Option "smart" allows for comparing two literal values, evaluating the value of typeof and null comparisons.

4 rules do not yet have ESLint equivalents

• import-spacing
• one-line
• whitespace
• no-reference-import

2 packages are required for new ESLint rules.

• eslint-plugin-prefer-arrow supports this rule:
  • only-arrow-functions = prefer-arrow/prefer-arrow-functions
• eslint-plugin-import supports these rules:
  • no-duplicate-imports = import/no-duplicates
  • ordered-imports = import/order (implementations differ)
