runInContext
external fun runInContext(code: String, contextifiedObject: Context, options: RunningCodeOptions = definedExternally): Any?(source)
external fun runInContext(code: String, contextifiedObject: Context, options: String = definedExternally): Any?(source)
The vm.runInContext()
method compiles code
, runs it within the context of the contextifiedObject
, then returns the result. Running code does not have access to the local scope. The contextifiedObject
object must have been previously contextified
using the {@link createContext} method.
If options
is a string, then it specifies the filename.
The following example compiles and executes different scripts using a single contextified
object:
const vm = require('node:vm');
const contextObject = { globalVar: 1 };
vm.createContext(contextObject);
for (let i = 0; i < 10; ++i) {
vm.runInContext('globalVar *= 2;', contextObject);
}
console.log(contextObject);
// Prints: { globalVar: 1024 }

v0.3.1
Return
the result of the very last statement executed in the script.
Parameters
code
The JavaScript code to compile and run.
contextifiedObject
The contextified
object that will be used as the global
when the code
is compiled and run.
