Kyl*_*ett 6 heroku node.js nestjs
我目前正在尝试部署由 Nest.JS CLI（从 5.3.0 版开始）生成的基本启动器模板，并且似乎在应用程序启动时超时。我想知道是否有人设法部署到 Heroku？
我不确定是否需要包含某种 Procfile？
此外，关于部署 Nest.JS 的信息似乎并不多
我尝试部署时的 Heroku 日志。

如果有人在部署此堆栈方面有任何经验，很高兴收到您的来信
Heroku 默认为您分配一个端口，并将该端口添加到环境变量（env）中，因此您可以将端口设置为固定数字，您需要将主文件更改为：
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
async function bootstrap() {
const app = await NestFactory.create(AppModule);
await app.listen(process.env.PORT || 3000);
}
bootstrap();

几个小时后...它已启动并运行！
1. package.json（注意：脚本、@nestjs版本、引擎）
{
"name": "nest",
"version": "0.0.0",
"description": "description",
"author": "",
"license": "MIT",
"scripts": {

"start:debug": "nodemon --config nodemon-debug.json",
"start:prod": "node dist/main.js",
"prestart:prod": "rimraf dist && npm run build",
"postinstall": "npm run prestart:prod",
"lint": "tslint -p tsconfig.json -c tslint.json",

"test:e2e": "jest --config ./test/jest-e2e.json",
"heroku-postbuild": "npm install --only=dev --no-shrinkwrap && npm run build"
},
"dependencies": {
"@nestjs/common": "6.7.2",
"@nestjs/core": "6.7.2",
"@nestjs/jwt": "0.2.0",
"@nestjs/mongoose": "5.2.2",
"@nestjs/passport": "5.1.0",

},
"devDependencies": {
"@nestjs/testing": "5.1.0",
"@types/express": "4.16.0",
"@types/jest": "23.3.1",
"@types/node": "10.7.1",
"@types/supertest": "2.0.5",

"prettier": "1.14.2",
"supertest": "3.1.0",

"ts-loader": "4.4.2",
"ts-node": "7.0.1",

},
"jest": {
"moduleFileExtensions": [
"js",
"json",
"ts"
],
"rootDir": "src",
"testRegex": ".spec.ts$",
"transform": {
".+\\.(t|j)s$": "ts-jest"
},
"coverageDirectory": "../coverage",
"testEnvironment": "node"
},
"engines": {
"node": "8.9.4"
}
}
2. Procfile（位置 - 与 package.json 相同） 是的，它是没有类型的文件。可以用记事本创建。
web: npm run start:prod
3. 启用安装 devDependency（如果需要）
heroku config:set NPM_CONFIG_PRODUCTION=false
我进行了以下更改来部署新生成的 Nest.js 应用程序：
main.ts- 改变了await app.listen(3000);
到
await app.listen(process.env.PORT || 3000);
新增Procfile内容：web: npm run start:prod
package.json- 添加了heroku-postbuild脚本，因此我的脚本如下所示：
"scripts": {
"build": "tsc -p tsconfig.build.json",
"format": "prettier --write \"src/**/*.ts\"",
"start": "ts-node -r tsconfig-paths/register src/main.ts",
"start:dev": "nodemon",
"start:debug": "nodemon --config nodemon-debug.json",
"prestart:prod": "rimraf dist && npm run build",
"start:prod": "node dist/main.js",
"lint": "tslint -p tsconfig.json -c tslint.json",
"test": "jest",
"test:watch": "jest --watch",
"test:cov": "jest --coverage",
"test:debug": "node --inspect-brk -r tsconfig-paths/register -r ts-node/register node_modules/.bin/jest --runInBand",
"test:e2e": "jest --config ./test/jest-e2e.json",
"heroku-postbuild": "npm install --only=dev --no-shrinkwrap && npm run build"
},
目前运行于： https: //server-ts.herokuapp.com
似乎这里的所有解决方案都适用于以前版本的 Nest。
在我的例子中（NestJS v7.5.1）启动命令看起来像"nest start"
添加依赖项后一切正常"@nestjs/cli"。
