我有一个 Node 应用程序,它将 typescript 文件编译到 dist
文件夹,然后通过 aws cdk 将这些文件用作 lambda 解析器。这是我的设置示例:
代码
register.ts
import ValidateUserFields from '../utils/forms';
exports.main = async function (event: any, context: any) {
return {
statusCode: 200,
};
}
注册-lambda-config.ts
import { Construct } from 'constructs';
import * as apigateway from 'aws-cdk-lib/aws-apigateway';
import * as lambda from 'aws-cdk-lib/aws-lambda';
import * as s3 from 'aws-cdk-lib/aws-s3';
export class FrontendService extends Construct {
constructor(scope: Construct, id: string) {
super(scope, id);
const api = new apigateway.RestApi(this, 'frontend-api', {
restApiName: 'Frontend Service',
description: 'This service serves the frontend.',
});
const functionName = 'register';
const handler = new lambda.Function(this, functionName, {
functionName,
runtime: lambda.Runtime.NODEJS_14_X,
code: lambda.Code.fromAsset('dist/src/lambda'),
handler: 'register.main',
});
const registerIntegration = new apigateway.LambdaIntegration(handler, {
requestTemplates: { 'application/json': '{ "statusCode": "200" }' },
});
const registerResource = api.root.addResource('register');
registerResource.addMethod('POST', registerIntegration);
}
}
tsconfig.json
{
"compilerOptions": {
"target": "ES2018",
"module": "commonjs",
"moduleResolution": "node",
"lib": ["es2018"],
"declaration": true,

"noImplicitAny": false,
"strictNullChecks": true,

"strictPropertyInitialization": false,
"outDir": "dist",
"typeRoots": ["./node_modules/@types"]
},
"exclude": ["node_modules", "cdk.out", "./dist/**/*"]
}
最后是我的 package.json 文件的脚本部分:
"scripts": {
"build": "tsc",
"watch": "tsc -w",
"cdk": "cdk",
"bootstrap": "cdk bootstrap",
"deploy": "cdk deploy && rimraf cdk.out",
"destroy": "cdk destroy",
"run-same-local-fe-api": "sam local start-api -p 4000 -t ./template.yaml",
"dev": "npm run build && npm run synth && concurrently --kill-others \"npm run watch\" \"npm run run-same-local-fe-api\"",
"synth": "cdk synth --no-staging > template.yaml"
},
问题
当我运行 npm run dev
时,它会将我的 typescript 文件编译到 dist
文件夹,其结构与我在 src
中的结构相同文件夹(我所有的 typescript 文件所在的位置)。但是,如果我的 register.ts
文件中有任何导入,我会遇到以下错误:
{"errorType":"Runtime.ImportModuleError","errorMessage":"Error: Cannot find module '../utils/forms'\nRequire stack:\n- /var/task/register.js\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js","stack":["Runtime.ImportModuleError: Error: Cannot find module '../utils/forms'","Require stack:","- /var/task/register.js","- /var/runtime/UserFunction.js","- /var/runtime/index.js"," at _loadUserApp (/var/runtime/UserFunction.js:202:13)"," at Object.module.exports.load (/var/runtime/UserFunction.js:242:17)","

从相关本地文件(如上面代码中所示的“../utils/forms”)导入时会发生这种情况,从 node_modules 导入时也会发生这种情况。当我查看 dist
文件夹中已编译的 register.js
文件时,我发现它已尝试解析导入:
"use strict";
var __importDefault = (this && this.__importDefault) || function (mod) {
return (mod && mod.__esModule) ? mod : { "default": mod };
};
Object.defineProperty(exports, "__esModule", { value: true });
const forms_1 = __importDefault(require("../utils/forms"));
const bucketName = process.env.BUCKET;
exports.main = async function (event, context) { ...
但是它显示上面的错误消息。我试过使用 require
而不是 import
但结果是一样的......
任何帮助将不胜感激!谢谢
最佳答案
表示如果没有minimal reproducible example,这真的很难回答;我至少会建议避免任何 require
和 exports
,并且只使用 import
/export
语句和以下在 tsconfig.json 中。
{
"compilerOptions": {
"module": "esnext"
}
}
