class Analyzer::Javascript::Express

Included Modules

Defined in:

analyzer/analyzers/javascript/express.cr

Constant Summary

EXPRESS_SOURCE_RE = Regex.union("require('express')", "require(\"express\")", "from 'express'", "from \"express\"", "express()", "express.Router(")

Precompiled once — a single PCRE2-JIT scan replaces six naive String#includes? substring scans over the whole file content. Regex.union auto-escapes each literal, so this is provably equivalent to the OR-of-includes? it replaces.

MAX_CHAIN_METHOD_DISTANCE = 1000

Constants for method chaining detection

MAX_CHAIN_SEARCH_DISTANCE = 5000
