在基于typescript的设置上运行sequelize播种程序时出错

我想在我的express api上使用sequelize seeder和migrations,目前所有模型都是使用sequelize-typescript以typescript编写的。
我尝试使用typescript添加我的第一个种子程序文件,但在运行时出现错误

20221028050116-feeds.ts种子文件

'use strict';

import { QueryInterface } from 'sequelize';

const feedTypes = [
  { id: 'b871a455-fddb-414c-ac02-2cdee07fa671', name: 'crypto' },
  { id: '68b15f90-19ca-4971-a2c6-67e66dc88f77', name: 'general' },
];
const feeds = [
  {
    id: 1,
    name: 'cointelegraph',
    url: 'https://cointelegraph.com/rss',
    feed_type_id: 'b871a455-fddb-414c-ac02-2cdee07fa671',
  },
];

module.exports = {
  up: (queryInterface: QueryInterface): Promise<number | object> =>
    queryInterface.sequelize.transaction(async (transaction) => {
      // here go all migration changes
      return Promise.all([
        queryInterface.bulkInsert('feed_types', feedTypes, { transaction }),
        queryInterface.bulkInsert('feeds', feeds, { transaction }),
      ]);
    }),

  down: (queryInterface: QueryInterface): Promise<object | object> =>
    queryInterface.sequelize.transaction(async (transaction) => {
      // here go all migration undo changes
      return Promise.all([
        queryInterface.bulkDelete('feed_types', null, { transaction }),
        queryInterface.bulkDelete('feeds', null, { transaction }),
      ]);
    }),
};

我在package.json文件中添加了2个命令以进行种子生成

"apply-seeders": "sequelize-cli db:seed:all",
"revert-seeders": "sequelize-cli db:seed:undo:all",

当我执行'npm run apply-seeders'时,它给出了以下错误

Sequelize CLI [Node: 16.17.0, CLI: 6.5.1, ORM: 6.23.2]

我做了一些深入研究,结果表明,您不能直接运行带有sequelize的typescript文件,如这里的THIS ANSWER
我修改了我的.sequelizerc文件以运行dist文件夹中的内容,而不是src文件夹中的内容

.续集文件

require("@babel/register");

const path = require('path');

module.exports = {
  config: path.resolve('dist', 'config', 'index.js'),
  'migrations-path': path.resolve('dist', 'data', 'migrations'),
  'models-path':     path.resolve('dist', 'data', 'models'),
  'seeders-path':    path.resolve('dist', 'data', 'seeders'),
};

现在运行此命令会出现不同类型的错误

    }
  }
}

有人能告诉我如何使用typescript运行播种程序和迁移文件吗

更新1

我安装了babel-plugin-module-resolver。现在它给了我一个新的错误。如果你正常运行ts文件,这个错误不会出现。当我运行console.log时,我可以看到所有的值,但是当程序运行时,那个方言根本无法加载,它似乎是从env文件中加载的

Loaded configuration file "dist/config/index.js".

ERROR: Dialect needs to be explicitly supplied as of v4.0.0

ERROR: Cannot read properties of undefined (reading 'detail')

更新2

我将postgres方言硬编码到配置文件中,但它仍然给我错误。

xbp102n01#

我在运行全局安装的sequelize命令时也遇到了同样的问题。这是一个奇怪的问题,因为在其他项目上它们都很好(不是TypeScript项目)。
这一次我尝试在本地安装sequelize并使用“npx”运行它们。它再次运行得很好。例如:

npm install --save-dev sequelize
npx sequelize db:migrate
npx sequelize db:migrate:status

我的设置是节点18.10,续集6.25.5,第8.8.0页。

我设法让事情顺利进行
你的.sequelizerc和config/index.ts绝对不能有导入导出,看来
这是我的**/.续集**
必需(“@巴别塔/寄存器”);
const path =需要('path');

module.exports = {
  config: path.resolve('dist', 'config', 'index.js'),
  'migrations-path': path.resolve('dist', 'data', 'migrations'),
  'models-path':     path.resolve('dist', 'data', 'models'),
  'seeders-path':    path.resolve('dist', 'data', 'seeders'),
};

下面是我的**/源代码/配置/索引.ts**

const config: any = {
  // if we are running tests we use an in memory db with sqlite
  dialect: process.env.DB_DIALECT,

  username: process.env.POSTGRES_USER,
  password: process.env.POSTGRES_PASSWORD,
  database: process.env.POSTGRES_DB,
  host: process.env.POSTGRES_HOST,
  port: Number(process.env.POSTGRES_PORT),
  define: {
    underscored: true,
  },
  logging: false,
};

module.exports = config;

我这里包括一个播种机
这是我的博客,我的博客是我的博客,我的博客是我的博客,我的博客是我的博客

import { QueryInterface } from 'sequelize';
import { feedTypes, feeds } from './fixtures';

const down = (queryInterface: QueryInterface): Promise<object | object> =>
  queryInterface.sequelize.transaction(async (transaction) => {
    // here go all migration undo changes
    return Promise.all([
      queryInterface.bulkDelete('feed_types', null, { transaction }),
      queryInterface.bulkDelete('feeds', null, { transaction }),
    ]);
  });

const up = (queryInterface: QueryInterface): Promise<number | object> =>
  queryInterface.sequelize.transaction(async (transaction) => {
    // here go all migration changes
    return Promise.all([
      queryInterface.bulkInsert('feed_types', feedTypes, {
        transaction,
        // @ts-ignore
        ignoreDuplicates: true,
      }),
      queryInterface.bulkInsert('feeds', feeds, {
        transaction,
        // @ts-ignore
        ignoreDuplicates: true,
      }),
      queryInterface.sequelize.query(
        `SELECT setval('feeds_id_seq', (SELECT MAX(id) FROM feeds))`,
        { transaction },
      ),
    ]);
  });

export { down, up };

操作的顺序在这里非常重要
1.创建所需种子

npx sequelize-cli seed:generate --name feeds
 npx sequelize-cli seed:generate --name tag_rules
 npx sequelize-cli seed:generate --name users

1.将每个生成的js文件的扩展名更改为ts
1.修改**.sequelizerc以从dist**读取传输的js文件
1.安装标签插件模块解析器

npm i --save-dev babel-plugin-module-resolver

所有种子文件都使用导入/导出,而使用require和module.exports的文件只有.sequelizerc和config文件
如果有人知道如何让这些与导入/导出语法一起工作,请随时提出建议。
这是我在package.json中的seed命令的样子

"apply-seeders": "node -r dotenv-flow/config ./node_modules/.bin/sequelize db:seed:all",
"revert-seeders": "node -r dotenv-flow/config ./node_modules/.bin/sequelize db:seed:undo:all",
