Scalable, strongly typed GraphQL schema development

export const messages = {
  /* istanbul ignore next */
  removedDeclarativeWrapping: (location: string, used: string[]) => `\
[declarativeWrappingPlugin]: The ${used.join(' / ')} object prop${
    used.length > 1 ? 's' : ''
  } used in the ${location} has been
moved to a plugin, as improved chaining APIs and the list() / nonNull() helpers functions are preferred.

On Fields: 

t.string('someField', { nullable: false })   ->    t.nonNull.string('someField')

On args: 

stringArg({ required: true })    ->    nonNull(stringArg())

If you would like to incrementally migrate, or prefer the existing API, it is now supported via the declarativeWrappingPlugin. 
Add this to your plugins array in your makeSchema config:

makeSchema({
  plugins: [declarativeWrappingPlugin(), ...]
})
`,

  removedDeclarativeWrappingShort: (location: string, used: string[]) => `\
[declarativeWrappingPlugin]: Additional warning for ${used.join(
    ' / '
  )} at ${location}. Add the declarativeWrappingPlugin() to the plugins array to disable this message.
`,
