• BP_RUNWAY_DENO_PERM_ENV=PORT
• BP_RUNWAY_DENO_PERM_HRTIME=false
• BP_RUNWAY_DENO_PERM_NET=true
• BP_RUNWAY_DENO_PERM_FFI=false
• BP_RUNWAY_DENO_PERM_READ=true

Environment variables

Configuration is done through environment variables.

Permissions can be generally enabled with a true value. So for example:

export BP_RUNWAY_DENO_PERM_NET=true

The above allows all net access, but it could be more granular with:

export BP_RUNWAY_DENO_PERM_NET=github.com:443
