[英]How to deploy a Typescript, NodeJS and Express app to Heroku
[英]Deploy Angular 5 + Nodejs Express app to Heroku
我有一個Angular 5 App。
這就是我在package.json中的內容
{

"@types/jquery": "3.2.16",
"angular2-image-upload": "^1.0.0-rc.0",
"bootstrap": "4.0.0-beta.2",
"core-js": "2.4.1",
"express": "^4.16.2",
"jquery": "3.2.1",

},
"devDependencies": {

"@types/jasmine": "~2.5.53",
"@types/jasminewd2": "~2.0.2",
"@types/node": "~6.0.60",

"tslint": "~5.7.0"
},
"engines": {
"node": "8.9.4",
"npm": "5.6.0"
}
}
我創建了一個包含這些內容的server.js 。
constexpress=require('express');
constapp=expres();
constpath=require('path');
app.us(express.static(__dirname+'/dist'));
app.listen(process.env.PORT||8080);
//PathLocationStradegy
app.get('/'function(req,res) {
res.sendFile(path.join(__dirname+'/dist/index.html'));
});
console.log('Console Listening');
然后,我運行這些命令
heroku auth:login
Email : johndoe@outlook.com
Password : #########
heroku create iproject-demo
heroku git:remote iproject-demo
git status
git add -A
git push heroku master
我試過這個

一切都很好看。

Released v3
https://iproject-demo.herokuapp.com/ deployed to Heroku
但是當我去應用程序時:
https://iproject-demo.herokuapp.com/
我明白了
我該如何進一步調試?
這是我如何使我的Angular應用程序部署和使用Heroku:
server.js
應如下所示: https : //hastebin.com/zavehahide.js package.json
,將@angular/cli
和@angular/compiler-cli
從devDependencies
到dependencies
package.json
,將postinstall: ng build --prod
和start: node server.js
到scripts
你應該好好去。
通常當我發生此錯誤時,我遇到節點依賴性問題。 嘗試刪除node_modules文件夾和dist文件夾。 從那里再次旋轉一切,這模仿了heroku將如何構建你的項目。
我建議更簡單,如果你想在heroku上部署后端作為api和github上的前端並在瀏覽計算機上激活跨源資源共享,我實際上正在構建這樣的應用程序,這是我的計划,否則如果你得到任何這樣你的好消息讓我更新
在您的server.js
您需要將http調用重定向到索引。
app.route('/*', function(req,res) {
res.redirect(__dirname + '/dist/index.html')
})
在上面它會將任何調用重定向到index.html。
在Server.js中更正您的代碼
const express = require('express');
const app = express();
const path = require('path');
app.use(express.static(__dirname+'/dist'));
app.listen(process.env.PORT||8080);
//Path Location Strategy
app.get('/', function(req, res) {
res.sendFile(path.join(__dirname+'/dist/index.html'));
});
console.log('Console Listening');
供將來參考 -
在點擊URL之前嘗試運行logs
命令。
$ heroku logs
然后查看日志以獲取更多詳細信息。
如果你要在heroku上建立產品,你將面臨內存超出問題。 所以自由類型不起作用。
因此,嘗試在本地構建並使用express提供dist文件。
在PROC文件中使用相同的命令
Heroku本地或Heroku本地網站:驗證您在本地的更改
在回答如何進一步調試。 運行您的應用程序,然后立即登錄Heroku,轉到您的應用程序,然后在“更多”下拉菜單中,單擊“查看日志”。 應該幫到你!
我相信有一種方法可以通過終端查看實時日志,這樣您就可以確切地看到失敗的內容。
嘗試在package.json文件中添加@angular-devkit/build-optimizer
作為包。
"dependencies": {
"@angular-devkit/build-optimizer": "^0.4.0",
...
}
這允許安裝后標志--aot
運行。 由於某種原因,這個包不再構建。
