Further comments

As discussed I've added resolvers in the plugin options of mercurius which should fix the issue.

Verification

I tried verifying this by enabling the fastify template and then using the updated cli (by running node dist/index.js in the create-graphback folder) but I received this error due to which the template didn't load and I wasn't able to test it. Please let me know if there are some other steps I can take to test if the subscriptions are working or not. Thanks.

Thanks for the PR. I've not verified it as I am away from laptop but it LGTM barring the small requested change inline.

I'll let @craicoverflow @wtrocki do the verification.

I think resolvers should include noteResolvers as in

Let's start this year with this small PR. Looking at it now

I cannot fix issues in PR. Can you add me to fork :) THX

How about running this from the code:

cd templates/ts-fastify-mongodb-backend
docker-compose up -d
yarn develop

PS: This doesn't seem to be working for me.

Thanks for pointing that out 😅 I've added them now @machi1990.

Added you @wtrocki :)

Same. It doesn't give an error in the terminal like last time, but shows that localhost refused to connect on the browser.

How about running this from the code:

Okay so this way of testing the template works if I don't specify the noteResolvers and simply leave the code like this:

  app.register((mercurius as any), {
    schema,
    resolvers,
    graphiql: true,
    context: contextCreator,
    subscription: true
  });

EDIT : found the reason why it was not working earlier. I had to merge the resolvers rather than simply specifying them in an array. I am now able to run the template @wtrocki. Though the subscriptions are still not working.

But even with this when I tested the subscriptions they were not working. Could it be because makeExecutableSchema is not creating the schema in a way acceptable by mercurius?

Will have to look for some other way to fix this then I guess 🤔

[RinkiyaKeDad]

Would it be a good idea to switch from mercurius to apollo-server-fastify?

[wtrocki]

Sounds good

Closing this since we're shifting to apollo-server-fastify. See #2256
