nyc-config-hook-run-in-this-context

Handy configuration for instrumenting with hook-run-in-this-context enabled.

Prior to node.js 11.11.0 require() was implemented using vm.runInThisContext(). This meant that running with hook-run-in-this-context enabled required disabling hook-require. Starting with node 11.11.0 require() is no longer implemented with vm.runInThisContext(), so hook-require still needs to be enabled. This base configuration enables hook-run-in-this-context and provides the correct setting for hook-require to ensure that modules loaded by require() are instrumented once.

First install the dependencies:

npm i nyc @istanbuljs/nyc-config-hook-run-in-this-context --save-dev

.nycrc

And write a .nycrc that looks like this:

{
    "extends": "@istanbuljs/nyc-config-hook-run-in-this-context"
    /* add custom settings */
}
