SDL generatsiya qilish

GraphQL SDL schemani qo'lda generatsiya qilish uchun (ya'ni ilovani ishga tushirmasdan, bazaga ulamasdan, resolverlarni bog'lamasdan va h.k.), GraphQLSchemaBuilderModuledan foydalaning.

1async function generateSchema() {
2  const app = await NestFactory.create(GraphQLSchemaBuilderModule);
3  await app.init();
4
5  const gqlSchemaFactory = app.get(GraphQLSchemaFactory);
6  const schema = await gqlSchemaFactory.create([RecipesResolver]);
7  console.log(printSchema(schema));
8}

Foydalanish

gqlSchemaFactory.create() metodi resolver klasslarining referencelaridan iborat massivni qabul qiladi. Masalan:

1const schema = await gqlSchemaFactory.create([
2  RecipesResolver,
3  AuthorsResolver,
4  PostsResolvers,
5]);

U shuningdek ikkinchi ixtiyoriy argument sifatida scalar klasslar massividan iborat argumentni ham qabul qiladi:

1const schema = await gqlSchemaFactory.create(
2  [RecipesResolver, AuthorsResolver, PostsResolvers],
3  [DurationScalar, DateScalar],
4);

Nihoyat, opsiyalar obyektini ham uzatishingiz mumkin:

1const schema = await gqlSchemaFactory.create([RecipesResolver], {
2  skipCheck: true,
3  orphanedTypes: [],
4});

• skipCheck: schema validatsiyasini e'tiborsiz qoldirish; boolean, default false
• orphanedTypes: aniq referens qilinmagan (object graphning bir qismi bo'lmagan) klasslar ro'yxati; ular generatsiya qilinadi. Odatda klass e'lon qilingan, lekin graphda boshqa joyda ishlatilmagan bo'lsa, u tashlab yuboriladi. Bu xossa qiymati klass referencelari massivi.
