Walkthrough

The DenoSubcommand::Deploy variant now carries an Option<&'static str> payload indicating deploy or sandbox. deploy_parse and tools::deploy signatures were updated to accept that subcommand payload. A new sandbox_subcommand() Command was added and registered in the root CLI. Argument parsing (flags_from_vec_with_initial_cwd and related logic) now returns Deploy(None) for deploy and Deploy(Some("sandbox")) for sandbox; main.rs forwards the payload to deploy.

151-153: Deploy subcommand payload handling looks good.

The pattern match correctly captures the subcommand payload and forwards it to tools::deploy::deploy. This aligns with the updated function signature.


738-738: Tunnel initialization guard is correct.

The wildcard pattern Deploy(_) properly matches the Deploy(Option<&'static str>) variant regardless of its inner value, correctly excluding all deploy operations from tunnel initialization as intended.

587-603: Consider a more typed representation for the deploy/sandbox mode

Encoding the deploy vs sandbox distinction as Deploy(Option<&'static str>) is a bit stringly-typed and easy to mistype (e.g. "sandbox" spelled differently in one place). A small dedicated enum (for example enum DeployMode { Default, Sandbox }) or at least a shared const SANDBOX_MODE: &str = "sandbox"; used everywhere would make this safer and clearer at call-sites and pattern matches.

1669-1683: Early routing of deploy/sandbox subcommands looks correct

Short‑circuiting deploy and sandbox here to call deploy_parse before the generic help/log‑level handling is a good fit for “pass everything through” semantics, and using Some("sandbox") vs None lines up with the new Deploy(Option<&'static str>) variant. No functional issues spotted.


1735-1743: Help handling for deploy/sandbox is consistent with new Deploy payload

Special‑casing deno help deploy and deno help sandbox to set argv = ["--help"], allow_all = true, and DenoSubcommand::Deploy(None|Some("sandbox")) keeps behaviour aligned between the two entry points and with the direct subcommand path. This looks coherent with the rest of the flag plumbing.


2080-2081: sandbox_subcommand wiring mirrors deploy_subcommand correctly

Registering sandbox_subcommand() in clap_root() and defining it with the same variadic args/trailing var‑arg/allow_hyphen_values(true) shape as deploy_subcommand() should make deno sandbox … behave identically from the parser’s perspective, differing only in the downstream Deploy(Some("sandbox")) tagging. This is consistent and minimal.

Also applies to: 2858-2866


5914-5927: deploy_parse extension for sandbox tagging is straightforward

Adding the subcommand: Option<&'static str> parameter and storing it as DenoSubcommand::Deploy(subcommand) cleanly separates plain deploy (None) from sandbox (Some("sandbox")) without changing existing argv handling. The function remains side‑effect‑free beyond populating flags, and there are no lifetime issues given the use of string literals at call‑sites.

cli/tools/deploy.rs (2)

18-21: LGTM!

Function signature update correctly adds the subcommand parameter to enable subcommand-aware deployment.


24-26: Remove this comment — the behavior is intentional.

The flags.argv is set during argument parsing in cli/args/flags.rs (line 5925), then intentionally narrowed to contain only the subcommand in deploy(). This is correct because @deno/deploy only needs the deployment target (e.g., "production", "sandbox") as its sole argument, not the full CLI arguments.

cli/main.rs (2)

150-152: LGTM!

Deploy subcommand handling correctly extracts and forwards the subcommand payload to the deploy function, aligning with the updated function signature.


737-737: LGTM!

Pattern correctly updated to Deploy(_) to handle both Deploy(None) and Deploy(Some("sandbox")) variants, ensuring tunnel initialization is skipped for all deploy subcommands.
