@formio/protected-eval v1.2.2
Form.io Protected Eval Plugin
This plugin makes formiojs library to use sandboxed eval with custom js-interpreter instead of default eval function.
Usage
import ProtectedEval from '@formio/protected-eval';
import { Formio } from 'formiojs';
Formio.use(ProtectedEval);
Differences with classic eval
Plugin doesn't allow usage of following variables in custom scripts:
instance
self
There is also a performance regression when this library is used. If you have more than 100 calculated values within your form, you will see a noticable performance decrease in the runtime performance of the form.
