Adding graphql resolver to HackaTalk server

I’d like to share how to add new resolvers to already implemented graphql server HackaTalk

Here, I’d like to add Gallery model which is a table that has columns photoURL and anid which is a primary key.

When you are just adding a new table to an existing database without changing any other table’s association, you don’t need to generate any migration script from sequelize. Let’s create Gallery model.

1. Add sequelize model.

2. Import Gallery model so it will export root models to index.ts.

3. Create gallery.graphql in src/schemas.

4. Import grallery.graphql in schema.graphql which is a root of schemas.

5. Let’s add a few resolvers for this model.

6. Run graphql-codegen.

7. Create gallery.ts in resolver dir.

8. Implement resolvers.

It is done for adding new resolvers to the running HackaTalk server. You can check out the pull request to find out more about it 💃.

P.S. We will work on the test code in the future post!
