This issue pertains to the following package(s):

• GraphQL Playground - Electron App
• GraphQL Playground HTML
• GraphQL Playground
• GraphQL Playground Express Middleware
• GraphQL Playground Hapi Middleware
• GraphQL Playground Koa Middleware
• GraphQL Playground Lambda Middleware

What version of graphql-playground(-electron/-middleware) are you experiencing the issue(s) on?

graphql-playground-html@1.6.0
graphql-playground-middleware-express@1.7.2

Example

import playground from 'graphql-playground-middleware-express';

app.get(
  '/playground',
  playground({
    endpoint: '/graphql',
    settings: { 'editor.fontSize': 16 }
  })
);

Playground properly uses that font size but still shows setting as 14 (the default) under settings. If I try to change the font size, theme, etc. from the client it doesn't take effect.

The only exception is request.credentials is actually able to be changed from the client. Likely related to this bug #791 as it can't be set by the server.

If I don't set any settings from the server

import playground from 'graphql-playground-middleware-express';

app.get(
  '/playground',
  playground({
    endpoint: '/graphql'
  })
);

then everything works fine.

I'm not sure if this is a bug or intended. But it would be ideal to be able to set default settings from the server but allow users to update those from the client and have them persist across sessions.
