💥 Missing Merger

• tslint-to-eslint-config version: X.X.X
• ESLint version: X.X.X

CLI Output

✨ 88 rules replaced with their ESLint equivalents. ✨

❗ 6 ESLint rules behave differently from their TSLint counterparts ❗
  Check ./tslint-to-eslint-config.log for details.

❌ 1 error thrown. ❌
  Check ./tslint-to-eslint-config.log for details.

🦖 1 rule is obsolete and does not have an ESLint equivalent. 🦖
  Check ./tslint-to-eslint-config.log for details.

♻ Consider using --comments to replace TSLint comment directives in your source files. ♻

✅ All is well! ✅

File Output

6 ESLint rules behave differently from their TSLint counterparts:
  * no-invalid-this:
    - Functions in methods will no longer be ignored.
  * @typescript-eslint/no-unused-expressions:
    - The TSLint optional config "allow-new" is the default ESLint behavior and will no longer be ignored.
  * prefer-arrow/prefer-arrow-functions:
    - ESLint does not support allowing standalone function declarations.
    - ESLint does not support allowing named functions defined with the function keyword.
  * eqeqeq:
    - Option "smart" allows for comparing two literal values, evaluating the value of typeof and null comparisons.
  * no-underscore-dangle:
    - Leading and trailing underscores (_) on identifiers will now be ignored.
  * padded-blocks:
    - ESLint's padded-blocks rule also bans a blank line before a closing brace.

Error: multiple output react/jsx-curly-spacing ESLint rule options were generated, but tslint-to-eslint-config doesn't have "merger" logic to deal with this.
