sfcc/no-ds-files

Disallows legacy .ds files in SFCC projects. Rename them to .js and keep the module CommonJS-compatible.

What it checks

• Flags the file itself when the filename ends in .ds
• Runs on the program node, so the whole file is treated as invalid once it is a .ds file

Why this rule exists

.ds is a legacy SFCC file extension. Keeping these files around makes code harder to modernize and can hide the fact that the project should be using standard JavaScript files.

Default behavior

• Severity: error
• Auto-fix: none

Example

cart.ds

module.exports = function () {
  return true
}

cart.js

module.exports = function () {
  return true
}
