Motivation

Migrates from cosmiconfig to in-house configliere for parsing configuration options.

Adds a protocol config option to allow users to choose serving over http or https.

Summary by CodeRabbit

  • New Features

    • Configure the Auth0 simulator with CLI flags, JSON files, environment variables, or programmatic options.
    • CLI help and version requests now display their results, and configuration errors are reported with a non-zero exit status.
    • Startup output displays the server URL using its bound address and port, falling back to localhost when needed.
  • Documentation

    • Expanded the README with configuration options and precedence guidance.
  • Updates

    • Updated the Auth0 client script used by the login page to version 9.32.0.

@jbolda Will you be able to help test this, and make improvements. I can't login with the default user due to SSL errors even when setting PROTOCOL=http.

Hmm, how are you testing it out? If it uses the auth0 libs, those tend to throw errors if they aren't pointing at https. Is that the error you are getting? That is why we had the instructions to use mkcert on first run. I might expect the tests to pass at least without setting up that cert.

I was running the start script, which executes ./example/index.mts. Then going to the /login route and entering the default user credentials. Auth0 webAuth was hitting https://localhost because the domain passed to it did not specify protocol (domain: new URL(serviceURL(req)).host). I'll ignore that for now.

For the unit tests, I modified them in a separate commit to pass protocol: 'http' option, so they now all pass without depending on system state.

As a bit of a separate question, do you have some requirements that prevent you from installing a local dev-only cert? I was considering automating that process more, a few libs can help some with it, but it the ramifications of trying to do it automatically were unclear.

Not really, mkcert is a dependency that hasn't been maintained for a few years. While I realize it might just be "complete" and doesn't require further work, I was just a bit wary of installing it and wanted to first figure out if the test suite can pass without it. And it did, so if it provides the same confidence it seems like an improvement because of a simpler setup.

Regardless, if you want to drop the third commit of this PR, please feel free.

I think clientID was explicitly used as that aligns with Auth0 docs. Could we confirm that and maybe link it to their docs for future reference?

The WebAuth instantiation in views/login.ts still specifies clientID, but using it as our config option was creating --client-i-d and CLIENT_I_D as the parameters.

I think we are going to have to put in an override API into configliere for this use case. I will do my best to whip that up here. I suspect that we are going to run into issues otherwise in getting it to work with auth0 libs if we don't follow their semantics.

Alright. Although I do think that this project should be able to use any naming format within itself, and only the interface layer with Auth0 needs to worry about using parameters that Auth0 accepts.

I don't inherently disagree. We want the incoming config to match whatever official auth0 accepts though. Also some of those variables are leaky into like the JWT if I recall.

I did get the PR going though, so we can update that soon here.

It looks like you have some good progress here. We will need to parse with a file as well. The inject is the new part of the API to help in handling it. This example that uses the newer inject which we will need to load a config file. After we have our parser, the return of that is effectively an object. That object is what we can pass directly to the auth0 simulator.

The slight adjustment here is that we don't do the config handling here. args.options should just be passed all of the data that we get from config. We won't parse in this function as that should be complete by the time we call this function. I don't think it will create a breaking change as before and after we only have an object. This distinction though means we can do more advanced parsing and pass in the result here.

How would start.cjs look? Would index.ts export getConfig which start.cjs will call and pass to simulation()?

Yep! Or at least the config parser. getConfig() could probably be removed as you would want to handle commands and then call simulation only in some cases (instead of the early return that you have).

Merge Risk: 🔵 Low · up to dc394

The HTTP startup message points users to the wrong URL, and invalid client IDs receive misleading guidance. The Zod upgrade may also change organization timestamps where they were omitted; confirm the intended API behavior. These are bounded issues for the owner to address or accept before merging.

Security Architecture Review

Security architecture risk: 🟠 High · up to dc394

A caller supplying simulator configuration without a protocol can now start the authentication server over HTTP, whereas the previous simulator always selected HTTPS. This affects login and token endpoints. Ordinary parsed configuration still defaults to HTTPS.

Retained concerns

  • High · security · inferred: Omitting protocol from the new direct simulator configuration path delegates to the foundation server's HTTP default, replacing the Auth0 simulator's former unconditional HTTPS selection. The resulting shared listener can carry login credentials and token requests without transport encryption.
Security review details

Security Blast Radius

  • inferred — The independently affected scope is a simulator instance's shared Auth0 listener and its mounted authentication routes, not an evidenced tenant-wide or infrastructure-wide change. Network reachability of a given instance remains deployment-dependent.

Security Findings and Attack Paths

  • inferred — A programmatic caller can supply an otherwise usable Auth0 configuration without protocol. The factory then omits its protocol argument, the foundation server selects HTTP, and a party able to observe traffic to that instance could read unencrypted credential or token exchanges. This implicit downgrade was absent when Auth0 always selected HTTPS.

Trust Boundaries and Controls

  • observed — The CLI and getConfig paths cross a schema-validation boundary and default to HTTPS. A directly supplied simulation config crosses neither boundary before its protocol reaches the listener; choosing HTTP through validated configuration is also permitted by the new public contract.

Resilience and Maintainability Implications

  • inferred — Separate parsed and direct configuration paths make the transport guarantee dependent on which public API a caller uses. The available startup output reports a port but does not identify the selected protocol, limiting visibility into an implicit HTTP fallback.

Hardening Proposals

  • proposed — Apply an Auth0-owned HTTPS fallback and validation to directly supplied configuration, so HTTP requires an explicit choice on either configuration path. Report the effective listener protocol at startup.

around the address in URLs). Modify the URL string construction to use the
protocol variable that should be available from the command-line arguments or
configuration, and add logic to check if the host is an IPv6 address (contains
colons) and wrap it in brackets before inserting it into the URL template.

with both the Auth0 client HTTPS requirement documented in lines 39-41 and the
default config sample shown in lines 56-57, ensuring consistent messaging
throughout the documentation.

In `@packages/auth0/src/types.ts`:
- Around line 28-32: The validation message for the clientID field is misleading

only enforces a maximum length, not an exact length. Either change the
validation to use .length(32) to enforce exactly 32 characters (which appears to
match the 32-character default value), or update the error message to say "must
be at most 32 characters long" to accurately reflect the maximum length
constraint. Choose based on whether exact or maximum length validation is
actually required for the clientID field.

Quick Start protocol example is inconsistent with the surrounding HTTPS guidance.

Line 48 says the default startup URL is http://localhost:4400, while Lines 39-41 and the default config sample (Lines 56-57) point to HTTPS. Please align these to a single default behavior to avoid setup confusion.

⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Misleading validation message for clientID.

The validation message says "must be 32 characters long" but max(32) enforces a maximum length, not an exact length. If exact length is required, use .length(32). If up to 32 is correct, update the message.

Suggested fix

If max length is intended:

  clientID: {
-   schema: z.optional(z.string().max(32, "must be 32 characters long")),
+   schema: z.optional(z.string().max(32, "must be at most 32 characters")),
    description: "auth0 client ID",
    default: "00000000000000000000000000000000" as const,
  },

Or if exact length is intended:

  clientID: {
-   schema: z.optional(z.string().max(32, "must be 32 characters long")),
+   schema: z.optional(z.string().length(32, "must be exactly 32 characters")),
    description: "auth0 client ID",
    default: "00000000000000000000000000000000" as const,
  },

In `@packages/auth0/src/types.ts` around lines 28 - 32, The validation message for
the clientID field is misleading because it says "must be 32 characters long"
but the schema uses .max(32) which only enforces a maximum length, not an exact

characters (which appears to match the 32-character default value), or update
the error message to say "must be at most 32 characters long" to accurately
reflect the maximum length constraint. Choose based on whether exact or maximum
length validation is actually required for the clientID field.

I haven't forgot about this PR! 😄

We have been hard at work revising hour configliere works using this example here as the guide. I just pushed a committed using the latest which we just published. I think this is going to give a good experience here.

It has even been moving into a different org now: https://github.com/bombshell-dev/configliere

Use the configured protocol in the startup URL.

Line 31 hardcodes https://. If a user sets --protocol http or PROTOCOL=http, the log still prints an HTTPS URL. Build the URL from result.value.protocol, and use "https" when it is not set.

Fix the misleading clientID validation message.

When clientID exceeds 32 characters, max(32) rejects it and the CLI error path can show "must be 32 characters long". This message incorrectly describes an exact-length requirement.

Suggested fix
-  clientID: z.optional(z.string().max(32, "must be 32 characters long")),
+  clientID: z.optional(z.string().max(32, "must be at most 32 characters long")),
...
-          clientID: z.string().max(32, "must be 32 characters long"),
+          clientID: z.string().max(32, "must be at most 32 characters long"),

Preserve the created_at contract.

Zod 4 applies defaults inside optional fields. githubOrganizationSchema.parse({ login: "test-org" }) can therefore add a generated created_at value, which GraphQL exposes as createdAt. If omission is required, remove the default:
