heroku failed 解決 Heroku Error R10 Web process failed to bind to $PORT within 60 seconds of launch 問題

解決辦法

Heroku 會動態為你的應用分配一個 port，所以你不能將 port 設為固定的值，請使用 process.env.PORT 取代。

const app = require("./webserver");
const port = 8080;

app.listen(process.env.PORT || port);

請注意，是 process.env.PORT 而不是 process.env.port，PORT 是大寫英文。
