hiiu overlay
Print the interception files that make every outbound request a recorded refusal. It prints and never writes.
hiiu overlay [path]Prints the interception overlay: the generated files that make every request leaving the app a recorded refusal unless it goes to loopback.
It prints and never writes. hiiu build is the writer.
Same constraints as the other read-only commands, and two runs of one input are
byte-identical.
Arguments and flags
[path] |
The repo or app directory to generate an overlay for. Default . |
--decisions <file> |
The confirmed decisions document to generate against |
Every global flag also applies.
Why you would run it
To read what hiiu is about to inject into a copy of your app before letting it, and to see which requests the overlay can and cannot cover on your framework.
The Next.js warning
A Next.js app's browser-originated requests are not intercepted, because Next
has no supported hook that runs a module before client application code.
Server-side requests, meaning server components, route handlers and
generateStaticParams, are covered.
That is a stderr warning and exit 0, not a failure. A target hiiu cannot
intercept at all is exit 3 with UNSUPPORTED_TARGET.
Exit codes
| Code | When |
|---|---|
0 |
Printed, warnings included |
3 |
Not a supported frontend app, or UNSUPPORTED_TARGET |
