从 postgraphile GraphQL 程序生成的查询/突变

Question

I don't believe its a big deal, but my GraphIQL generates all of its queries and mutations from my PSQL schema. Is it possible to have it general a file for me with each change that I can use directly in my project? As currently I am having to write manually my queries/mutations as below and often I am changing the schema and then having to update all my instances of this.

export const UPDATE = gql`
  mutation updateOrganiserByOrganiserId(
    $organiserName: String!
    $address: String
    $address2: String
    $city: String
    $country: String
    $postCode: String
    $manufacturerId: Int
    $organiserId: Int!
    $competitionSystemId: Int!
  ) {
    updateOrganiserByOrganiserId(
      input: {
        clientMutationId: "updateOrganisation"
        organiserId: $organiserId
        organiserPatch: {
          organiserName: $organiserName
          address: $address
          address2: $address2
          city: $city
          country: $country
          postCode: $postCode
          manufacturerId: $manufacturerId
          competitionSystemId: $competitionSystemId
        }
      }
    ) {
      clientMutationId
    }
  }

No, there is no way to do that.

often I am changing the schema

That's your actual problem. Your schema should be immutable, and only ever be extended but never changed. From the GraphQL best practices on versioning : " new capabilities can be added via new types and new fields on those types without creating a breaking change. This has led to a common practice of always avoiding breaking changes and serving a versionless API. "

So even when your Postgres database schema changes, keep your GraphQL schema the same (or add new fields to it) so that your mutations simply keep working. Postgraphile provides a great lot of tools (renaming of fields, deprecation annotations, computed fields, …) to support that.
