Check API

Theme Check uses static analysis. It parses theme files into an AST, and then calls the appropriate checks to analyze it.

An AST is a tree of node, representing the theme file.

Checks are Ruby classes with callback methods:

• on_TYPE that runs before a node of the specific TYPE is visited.
• after_TYPE that runs after a node of the specific TYPE is visited.

There are three types of checks currently supported:

• LiquidCheck
• HtmlCheck
• JsonCheck
