# @mongodb-js/oidc-mock-provider

This is a package for internal testing. It should not be considered
production-ready or used in deployed applications.

This OIDC provider does not provide any form of genuine authentication
or authorization functionality.

## Requirements

Node.js >= 20.19.5, npm >= 11.6.0. Running as
`npx @mongodb-js/oidc-mock-provider ...` is typically the easiest way
to install/run this tool.

## Examples

Start the OIDC mock identity provider server on port 28200:

Start the server on a random port and bind to all interfaces:

```sh
npx @mongodb-js/oidc-mock-provider --port 0 --bind_ip_all
```

Return a custom JSON payload and set token expiry to 10 minutes:

```sh
npx @mongodb-js/oidc-mock-provider -P '{"sub":"user123"}' -e 600
```

Log all HTTP requests and provide additional issuer metadata:

```sh
npx @mongodb-js/oidc-mock-provider -l --issuer-metadata '{"custom":"value"}'
```
