[Question] With large resource collections, how can I enforce "first" to be less than, say, 100?

[seandavi]

I'm used to working on python/graphene, so my question is likely simply a matter of my not being familiar with graphql-js and how neo4j-graphql fits in.

Do you mean something like that?

type Query {
  usersBySubstring(substring: String, first: Int): [User]
    @cypher(
      statement: "MATCH (u:User) WHERE u.name CONTAINS $substring LIMIT $first RETURN u"
    )
}

Thanks, @BrenoMazieiro.

Yes. I'd like to enforce that "first" is specified in the graphql query and is 100 or less (or default to 100) for all collections (as an example). I am exposing a graphql API to the public and want to do what I can to protect the resource.

Of course, any other suggestions on the general topic of public graphql apis backed by neo4j would be much appreciated.

@seandavi this is an "example repository", I believe it is not for production, you should do a lot of things if you want something "production like", like adding authentication and authorization at least.

Anyway:

Whats about this?

type Query {
  usersBySubstring(substring: String, first: Int = 100): [User]
    @cypher(
      statement: "MATCH (u:User) WHERE u.name CONTAINS $substring LIMIT $first RETURN u"
    )
}
