如何获取 Supabase 数据库类型？

Question

我来自 Firebase，我正在尝试获取数据库的类型。例如，我习惯于像这样获取时间戳的类型：

import type { Timestamp } from 'firebase/firestore';

export type User = {
 //..   
 createdAt: Timestamp;   
 updatedAt: Timestamp | null; 
};

如何获取 Supabase 数据库的类型？

Answer 1

您可以查看 Supabase 官方文档以了解生成类型。还有一些例子可以参考。

https://supabase.com/docs/guides/api/generate-types

import { NextApiRequest, NextApiResponse } from 'next'
import { createClient } from '@supabase/supabase-js'
import { Database } from '../types/supabase'

const supabase = createClient<Database>(
  process.env.NEXT_PUBLIC_SUPABASE_URL,
  process.env.SUPABASE_SECRET_KEY
)

export default async (req: NextApiRequest, res: NextApiResponse) => {
  const allOnlineUsers = await supabase.from('users').select('*').eq('status', 'ONLINE')
  res.status(200).json(allOnlineUsers)
}

Answer 2

您应该为各个表定义自己的类型，例如

  import supabase from '~/lib/supabase'
  import type { Database } from '~/lib/database.types'

  async function getMovies() {
    return await supabase.from('movies').select('id, title, actors(\*)')
  }

  type Actors = Database['public']['tables']['actors']['row']
  type MoviesResponse = Awaited<ReturnType<typeof getMovies>>
  type MoviesResponseSuccess = MoviesResponse['data'] & {
  actors: Actors[]
  }
