Function: createGroup()

function createGroup<TContext>(config): CompiledGroup<TContext>;

Defined in: packages/core/src/core/createGroup.ts:174

Example

const tasks = createGroup({
  name: 'tasks',
  middleware: [logMiddleware],
  actions: {
    list: {
      readOnly: true,
      handler: async (ctx) => success(await ctx.db.tasks.findMany()),
    },
    create: {
      schema: z.object({ title: z.string() }),
      handler: async (ctx, args) => success(await ctx.db.tasks.create(args)),
    },
  },
});

const result = await tasks.execute(ctx, 'create', { title: 'Buy milk' });
