Error: Cannot find module 'graphql'

[Micha]

We get the following error when trying to start our application after installing the nestjs-keycloak-admin package:

We can't use nestjs-keycloak-admin without installing graphql, even though we don't use graphql. It runs after installing graphql manually as a dependency in our project.

Is there any way to use this package without installing graphql manually?

Hey @MichaHumbel, which version are you currently using?

Hey @MichaHumbel, which version are you currently using?

nestjs-keycloak-admin: 1.8.6
Node: v17.8.0

[Yagiz Nizipli]

I don't think it's possible in a not-ugly way. I totally understand where this is coming from. What I can come up with is:

1. You don't want to increase the node_modules size
2. You don't want to install any package you don't use

Whole logic for detecting whether or not a request is coming from GraphQL is implemented in utils/extract-request.ts (https://github.com/anonrig/nestjs-keycloak-admin/blob/master/src/utils/extract-request.ts#L5)

Since extractRequest function sits on top of the core logic of Nest.js applications (in all guards), I could not find a solution that does not duplicate existing code.

I believe there are some of the possible solutions (which might not be the best ones):

1. Split each guard to GraphQL and HTTP: Importing each guard from respective places like nestjs-keycloak-admin/graphql/guards and nestjs-keycloak-admin/http/guards
2. Dynamically load @nestjs/graphql package if the package is installed. If not, do not even try to understand if the request is a graphql request.

I'd be happy to discuss all possible solutions and reduce the size of this package.

same question here.... I'm not using graphQL so I shouldn't be forced to manually add @nestjs/graphql;

Tried this out with versions: 1.8.2 and 1.8.6 (get same issue for both versions)

For the latest version(1.8.7) I have other problem related with a require that sits somewhere in the code:

/Users/bernardo/Documents/incubeta-repos/creamos-client-management-service/node_modules/nestjs-keycloak-admin/dist/main/service.js:18
const keycloak_admin_client_1 = __importDefault(require("@keycloak/keycloak-admin-client"));
^
Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/bernardo/Documents/incubeta-repos/creamos-client-management-service/node_modules/@keycloak/keycloak-admin-client/lib/index.js from /Users/bernardo/Documents/incubeta-repos/creamos-client-management-service/node_modules/nestjs-keycloak-admin/dist/main/service.js not supported.
Instead change the require of index.js in /Users/bernardo/Documents/incubeta-repos/creamos-client-management-service/node_modules/nestjs-keycloak-admin/dist/main/service.js to a dynamic import() which is available in all CommonJS modules.

@P1K3N due to @keycloak/keycloak-admin-client being a ESM only package after 19.x release, it's required you to use ESM mode with Node.

Please look into the issues keycloak/keycloak-nodejs-admin-client#523, keycloak/keycloak-nodejs-admin-client#519 and keycloak/keycloak-nodejs-admin-client#487

It seems the keycloak-nodejs-admin-client repository is moved: https://github.com/keycloak/keycloak-nodejs-admin-client
