问题 I have a small Node.js / Express app deployed to Heroku. I'd like to use a lightweight database like NeDB to persist some data. Is it possible to periodically backup / copy a file from Heroku if I used this approach? 回答1: File-based databases aren't a good fit for Heroku due to its ephemeral filesystem (bold added): Each dyno gets its own ephemeral filesystem, with a fresh copy of the most recently deployed code. During the dyno’s lifetime its running processes can use the filesystem as a

问题 My app has some additional logging, it works fine on a local machine and even on Heroku local. When I push it to Heroku, it raises a FileNotFoundError .

问题 I am trying to host a discord bot on Heroku (Discord JDA, Maven). I do this by connecting to Github and then deploying. The bot 'deploys' (view attachment) but doesn't actually work (view attachment). What could I be doing wrong, or has anyone else come across a similar issue? 回答1: Quick and dirty way to deploy it: You'll need to setup a Procfile, extensive info on that right here: https://devcenter.heroku.com/articles/procfile The procfile is basically a file with no extension that tells the

问题 I'm developing a rails app, that uses vue through webpacker. Inside of the vue app I import vuetify and vuetify.css like so: import Vue from 'vue' import Vuetify from 'vuetify' import VueRouter from 'vue-router' import 'vuetify/dist/vuetify.min.css' import App from '../app.vue' import Axios from 'axios' import VueAxios from 'vue-axios' import Vuex from 'vuex' Works fine locally, but when pushed to heroku it no longer works.
