GraphQLNonNull and empty strings

[jsonmaur]

I assumed that if I have an argument with type new GraphQLNonNull(GraphQLString), it would not allow empty strings. But it seems this is not the case. Is there another way to make sure empty strings are caught for required arguments?

Currently GraphQL doesn't handle form-style validation, like ensuring the length of a string (an empty string is definitely not null, especially in JavaScript).

You might be interested in this thread, which talks about using custom input types for validation like this: #361

Yeah that's what I thought. Thanks, I'll keep an eye on that thread.

In the model do it like this:

const mongoose = require("mongoose");
const Schema = mongoose.Schema;

const buinessSchema = new Schema({
  name: { type: String, required: true, unique: true },
  address: { type: String, required: true },
  phone: { type: String, required: true },
  email: { type: String, required: true },
  website: { type: String, required: true },
  currency: { type: String, required: true },
  aboutus: { type: String, required: true },
  terms: String,
  slogan: String,
  logo: { type: String, required: true }
});

module.exports = mongoose.model("Buiness", buinessSchema);

that will include both null and empty strings
