Array Of Objects Convert Into Object Of Objects When I Use Apollo

In our project we use Apollo client to send queries to GraphQL. Strangely it converts the variables into object of objects. let variables = [{myField: 'myVal'}]; graphql.mutate('mu

Solution 1:

When executing a query, GraphQL expects variables to be an object where the key is the variable name and the value is the corresponding variable value. Every variable used within a document (the entire query you send) must be declared next to the operation definition for the document. For example, if you have a variable named firstName that was a String:

mutation SomeOperationName ($firstName: String) {
  # your mutation here
}

You can include any number of variables:

mutation SomeOperationName ($firstName: String, $lastName: String, points: Int)

Variables can also be lists:

mutation SomeOperationName ($names: [String], points: Int)

In all these cases, however, the value for variables you pass to mutate still needs to be an object:

{
  names: ['Bob', 'Susan'],
  points: 12,
}

In your example, you've only defined a single variable, data, that you've told GraphQL is a List of MyInputType. You can't pass in myField as a variable because you have not told GraphQL that variable exists. However, if myField is a field on MyInputType, then your variables just needs to look like this:

{
  data: [
    {
        myField: 'someValue'
    },
    {
        myField: 'someOtherValue'
    },
  ],
}
