Module Nodes

Provides classes representing particular kinds of data flow nodes, such as nodes corresponding to function definitions or nodes corresponding to parameters.

Import path

import semmle.javascript.dataflow.Nodes

Predicates

dependencyModuleImport	Gets a (default) import of the given dependency `dep`, such as `require("lodash")` in a context where a package.json file includes `"lodash"` as a dependency.
globalObjectRef	Gets a data flow node corresponding to an access to the global object, including `this` expressions outside functions, references to global variables `window` and `global`, and uses of the `global` npm package.
globalVarRef	Gets a data flow node corresponding to an access to global variable `name`, either directly, through `window` or `global`, or through the `global` npm package.
moduleImport	Gets a (default) import of the module with the given path, such as `require("fs")` or `import * as fs from "fs"`.
moduleMember	Gets a data flow node that either imports `m` from the module with the given `path`, or accesses `m` as a member on a default or namespace import from `path`.

Classes

ArrayConstructorInvokeNode	A data flow node corresponding to a `new Array()` or `Array()` invocation.
ArrayCreationNode	A data flow node corresponding to the creation or a new array, either through an array literal, an invocation of the `Array` constructor, or the `Array.from` method.
ArrayLiteralNode	A data flow node corresponding to an array literal expression.
CallNode	A data flow node corresponding to a function call without `new`.
ClassNode	A data flow node corresponding to a class definition or a function definition acting as a class.
ExprNode	A data flow node corresponding to an expression.
FunctionNode	A data flow node corresponding to a function definition.
GlobalVarRefNode	A data flow node corresponding to a global variable access through a simple identifier.
InvokeNode	A data flow node corresponding to a function invocation (with or without `new`).
MemberKind	The string `method`, `getter`, or `setter`, representing the kind of a function member in a class.
MethodCallNode	A data flow node corresponding to a method call, that is, a call of form `x.m(...)`.
ModuleImportNode	A data flow node representing an import of a module, either through an `import` declaration, a call to `require`, or an AMD dependency parameter.
NewNode	A data flow node corresponding to a `new` expression.
ObjectLiteralNode	A data flow node corresponding to an object literal expression.
ParameterNode	A data flow node corresponding to a parameter.
PartialInvokeNode	A data flow node that performs a partial function application.
RegExpConstructorInvokeNode	An invocation of the `RegExp` constructor.
RegExpCreationNode	A data flow node corresponding to a regular expression literal or an invocation of the `RegExp` constructor.
RegExpLiteralNode	A data-flow node corresponding to a regular-expression literal.
ThisNode	A data flow node corresponding to the `this` parameter in a function or `this` at the top-level.
VarAccessBarrier	A guard node for a variable in a negative condition, such as `x` in `if(!x)`. Can be added to a `isBarrier` in a data-flow configuration to block flow through such checks.
