@endo/lockdown
We often need to upgrade a JavaScript environment to HardenedJS as a side
effect of importing a module, so that later modules can rely on the hardened
environment.
The @endo/lockdown package simply ensures that SES has both initialized
and locked down the environment.
import '@endo/lockdown'
import 'hardened-modules...';The HardenedJS environment is a subset of the Endo environment.
Use @endo/init for a more comprehensive upgrade.
