Question

我正在使用NestJS版7.1.0和serverless，并使用nestjs swagger创建api文档。在本地，它像冠军一样工作，但是部署后出现错误。

swagger-ui-express package is missing

我在这里看到了一些问题，但仍无法解决。 https://github.com/nestjs/swagger/issues/277

这是我的package.json

"dependencies": {
    "@nestjs/common": "^7.1.0",
    "@nestjs/core": "^7.1.0",
    "@nestjs/passport": "^7.0.0",
    "@nestjs/platform-express": "^7.0.7",
    "@nestjs/swagger": "^4.5.8",
    "aws-serverless-express-binary": "^1.0.1",
    "class-transformer": "^0.2.3",
    "class-validator": "^0.11.1",
    "dayjs": "^1.8.24",
    "dotenv": "^8.2.0",
    "dynamodb-data-types": "^3.0.1",
    "express": "^4.17.1",
    "faker": "^4.1.0",
    "jest": "^24.9.0",
    "jwks-rsa": "^1.6.0",
    "latinize": "^0.4.1",
    "lodash": "^4.17.15",
    "mime-types": "^2.1.26",
    "passport": "^0.4.1",
    "passport-jwt": "^4.0.0",
    "reflect-metadata": "^0.1.13",
    "rimraf": "^3.0.0",
    "rxjs": "^6.5.3",
    "serverless-dynamodb-local": "^0.2.39",
    "swagger-ui-express": "^4.1.4",
    "tslint-loader": "^3.5.4",
    "uuid": "^3.3.3",
    "winston": "^3.2.1"
  },

这是配置：

const options = new DocumentBuilder()
  .setTitle("My APIs")
  .setDescription("APIs description")
  .setVersion("1.0")
  .addTag("cats")
  .build();

const document = SwaggerModule.createDocument(app, options);
SwaggerModule.setup("api", app, document);

任何帮助！

我想出了解决方案，希望对您有所帮助。我添加了一个伪造的终结点，以确保swagger-ui-express运行后不会删除webpack。

if (event.path === "/api") {
    event.path = "/api/";
} else if (event.path.includes("/swagger-ui")) {
    event.path = event.path.replace("/swagger-ui", "/api/swagger-ui");
}

// Fake to keep swagger-ui-express work after deploy
if (event.path === "/fake-swagger-ui-express") {
    swaggerUi.setup(null);
}

您碰巧正在使用纱线工作区吗？我现在遇到了同样的问题，在本地一切正常，但是在我们的集群上崩溃了。

如果是，那么尝试将其添加到使用swagger模块的API的package.json中： "workspaces": { "nohoist": ["swagger-ui-express"] }

部署后缺少NestJS swagger-ui-express软件包
