How can I get a field of type array that allows nullable values when using the code-first approach in nestjs graphql.
The example shows that
@Field(type => [String])
ingredients: string[];
generates [String!]! in the schema.gql file. How can I get just [String]? using {nullable: true} gives me [String!]
I was hoping to find some type of utility or parameter in the @Field decorator, but It seems it isn't
You need to set @Field(() => [String], { nullable: 'itemsAndList' }) as described in the docs
When the field is an array, we must manually indicate the array type in the Field() decorator's type function, as shown below:
@Field(type => [Post])
posts: Post[];
Hint Using array bracket notation ([ ]), we can indicate the depth of the array. For example, using [[Int]] would represent an integer matrix.
To declare that an array's items (not the array itself) are nullable, set the nullable property to 'items' as shown below:
@Field(type => [Post], { nullable: 'items' })
posts: Post[];`
If both the array and its items are nullable, set nullable to 'itemsAndList' instead.
