💡 Hint

Common Mistakes

Using 'introspect' instead of 'introspection'.

Setting introspection to true disables it (it's the opposite).

Setting introspection: false disables introspection queries in Apollo Server.

2fill in blank

medium

💡 Hint

Common Mistakes

Using 'production' instead of 'development'.

Forgetting to use quotes around the environment string.

Introspection is usually enabled only in development to prevent exposing schema details in production.

3fill in blank

💡 Hint

Common Mistakes

Using 0 or null instead of false.

Leaving the option undefined.

The introspection option expects a boolean. Use false to disable it.

4fill in blank

hard

Fill both blanks to disable introspection and enable playground only in development.

GraphQL

const server = new ApolloServer({ schema, introspection: [1], playground: [2] });

Drag options to blanks, or click blank then click option'

Afalse

Bprocess.env.NODE_ENV === 'development'

Ctrue

Dprocess.env.NODE_ENV === 'production'

💡 Hint

Common Mistakes

Enabling introspection by mistake.

Enabling playground in production.

Introspection is disabled with false. Playground is enabled only in development environment.

5fill in blank

hard

Fill all three blanks to create a GraphQL server that disables introspection, disables playground, and sets a custom schema.

GraphQL

const server = new ApolloServer({ schema: [1], introspection: [2], playground: [3] });

Drag options to blanks, or click blank then click option'

Bfalse

Dtrue

💡 Hint

Common Mistakes

Using true for introspection or playground.

Not passing the schema variable correctly.

The server uses a custom schema myCustomSchema, disables introspection and playground by setting both to false.
