Static linter for templates

Linting allows you see some warnings about template code in STDERR. List of checks you can find in migration guides.

cd migration/ && npm i

cd ../

./migration/lib/index.js --lint --input ./path-to-templates/ --from 7 --to 8

where

  • lint lint option (if not present script will rewrite your templates)
  • input path to templates (relative to current directory or absolute)
  • 7 is major version from. If you specify 0 common check will be included.
  • 8 is major to lint.

Result of linting is console warning like this:

BEM-XJST WARNING:
>>>> Function that returns a literal can be replaced with literal itself.
>>>> migration/tmpls/template.js:8:1
>>>> function() { return 42; }
