NOTE: I'm using express 4.17.1, and node version 14.
The host is working very well i'm only having problem with functions
EDIT: I change the ".gif" and it continues showing error, so I decided to remove it, only for debug, well, the error continues to another image(another PNG), the error appears to be in images

It looks like you're trying to import a *.gif image somewhere (but not in the provided code); by default, importing GIFs is not supported.
If I'm correct, then you need to setup Webpack (or its alternatives) in order to handle imports of GIF files.

VUE JS 3 TypeError: vue.initDirectivesForSSR is not a function

I've tried to build my vue web app using this config, but I got these errors, I've tried this issue but I can't found someone got the same issue as me. How can I deal with this issue, by the way the build succeeded, the issues happened when I tried to run node src/server.jsx? Thanks in advance
$ node src/server.jsx

Thank you guys
Try updating your Vue 3 version.
My #vue/server-renderer package was 3.2.20 and my Vue version was 3.2.6. I bumped my Vue version to 3.2.20 and it's working great now. :)

It apparently fails to find the module

The code is this and when I try to turn my bot on I get a error that it can't find the file to execute the command.
const fs = require('fs');
module.exports = (client, Discord) =>{
const commandFolders = fs.readdirSync('./commands')
for(const folder [enter image description here][1]of commandFolders){
const command_files = fs.readdirSync(`./commands/${folder}`).filter(file => file.endsWith('.js'))
for(const file of command_files){
const command = require(`./commands/${folder}/${file}`);
if(command.name){
client.commands.set(command.name, command);
}else {
continue
}
}
}
}
This is the error I get when I turn my bot on.

Directory Structure:
Your command_handler.js file is inside /handlers/. ./ is used to access the current directory.
Doing ./commands/ doesn't work because the commands folder is not inside of /handlers/
You must first exit the current folder (using ../), then access.
Change all of the './commands' to '../commands'

cannot import modules in react

I have made this utility which i want to import in another file :
const fetch = require('node-fetch');
/**
* #todo Add documentation
*/
class SimplicateApi {
constructor(key,secret){
this._key = key;
this._secret = secret;
this.baseUrl = 'https://simplicate.nl/api/v2';
this.options = {
headers: {
'Content-Type': 'application/json',
'Authentication-Key' : this._key,
'Authentication-Secret' : this._secret
}
}
}
get(endpoint) {
return fetch(`${this.baseUrl}${endpoint}`, this.options)
.then(res => res.json())
.then(json => json);
}
}
export default SimplicateApi;
In another file im importing it like this :
import SimplicateApi from '../../utils/SimplicateApi';
The error I receive :
(function (exports, require, module, __filename, __dirname) { import
{SimplicateApi} from '../../utils/SimplicateApi';
^

I removed everything even the fetch and just exported the class like this :
// import fetch from 'node-fetch';
/**
* #todo Add documentation
*/
class SimplicateApi {
}
export default SimplicateApi;
Now im importing it like this :
import SimplicateApi from '../../utils/SimplicateApi';
The error still looks like :
(function (exports, require, module, __filename, __dirname) { import SimplicateApi from '../../utils/SimplicateApi';

Your code is mixing both CommonJs module and ES6 module.
In react, you should use ES6 module.
CommonJs module does not supported by React.You need to configure Babel for this.
const fetch = require('node-fetch'); // this wronng import syntax in React.
Changes should be
// if you are in react.
import fetch from 'node-fetch'; // for react
//if you are in Node.
class SimplicateApi {
}
module.exports = SimplicateApi;

how to redirect all server requests to a function in Firebase Hosting

Trying to implement SSR with Firebase so I'm using a function to prerender each page of a React App. It's working well except the home page, so it must be either the match is wrong on the firebase redirect or possibly on the express route itself.
firebase.json
{
"firestore": {
"rules": "firestore.rules",
"indexes": "firestore.indexes.json"
},
"functions": {
"predeploy": [
"npm --prefix \"$RESOURCE_DIR\" run lint"
]
},
"hosting": {
"public": "build",
"rewrites": [
{
"source": "**",
"function": "contentServer"
}
],
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
]
}
}
contentServer.js
import * as functions from 'firebase-functions';
import * as fs from 'fs';
import * as path from 'path';
import React from 'react';
import Helmet from 'react-helmet';
import { renderToString } from 'react-dom/server';
import Server from '../browser/Server.js';
const express = require('express');
const app = express();
// might be this? Also tried /**
app.get(['**'], (request, response) => {
const context = {};
const location = request.url;
console.log('Processing request for ', location);
let appCode;
try {
appCode = renderToString(<Server context={context} location={location} />);
} catch (err) {
appCode = 'with error';
}
// const appState = {
// pageTitle: 'Hello World',
// };
// const preloadedState = JSON.stringify(appState).replace(/</g, '\\u003c');
const fileName = path.join(__dirname, '../index.html');
const htmlTemplate = fs.readFileSync(fileName, 'utf8');
const head = Helmet.renderStatic();
const responseString = htmlTemplate
.replace('<div id="root"></div>', `<div id="root">${appCode}</div>`)
.replace('<title>React App</title>', `${head.title}\n${head.link}`);
return response.send(responseString);
});
export default functions.https.onRequest(app);
Curl
I run firebase serve --only functions,hosting
Then use curl to check the response:
curl http://localhost:5000 - does not render the home page - just the standard react page
curl http://localhost:5000/ - also does not work - just the standard react page.
curl http://localhost:5000/contact-us - works well and returns the contact us page, all other pages on the site work and trigger the function.
If you want redirect every single URL to your host to an express app in Cloud Functions, you will need to do the following:
Make sure there is no index.html in your public hosting folder (otherwise it will always be served with the path /).
Configure Firebase hosting in firebase.json to rewrite all urls to a function (you are currently doing this in your "hosting" block, which is good):
"rewrites": [
{
"source": "**",
"function": "contentServer"
}
]
Write a Cloud Function exported with the same name as the function in the rewrite, and attach an express app that handles the route wildcarded with *. In index.js in your functions folder, minimally:
const functions = require('firebase-functions')
const express = require('express')
const app = express()
app.get("*", (request, response) => {
response.send("OK")
})
exports.contentServer = functions.https.onRequest(app)
If you run this locally with firebase serve --only hosting,functions, every path that you send to localhost:5000 will say "OK".

SyntaxError: Unexpected token using async and babel in koa

I have this simple app made using the last alpha version of Koa. In order to use `async/wait Babel.Js is required.
'use strict';
// babel registration (runtime transpilation for node)
require('./server.babel');
const Koa = require('koa');
const app = new Koa();
// define logger - this will be always executed
const logger = async (context, next) => {
const start = new Date;
await next();
const ms = new Date - start;
console.log(`${context.method} ${context.url} - ${ms}ms`);
}
const index = (context) => {
context.body = 'Hello World';
}
app.use(logger);
app.use(index);
app.listen(3000);
console.info(`The app is listening on port 3000`);
This is the hook to activate the transpiling.
const fs = require('fs');
let config;
try {
config = JSON.parse(fs.readFileSync('./.babelrc'));
} catch (error) {
console.error('==> ERROR: Error parsing your .babelrc.');
console.error(error);
}
require('babel-core/register')(config);
and this is the config file:
{
"plugins": ["transform-async-to-generator"]
}
Unfortunately when I try to run the project I get the following error:
const logger = async (context, next) => {

I have no idea why I get this error. I'm using the last Node.Js version 5.1.0 and Babel 6.2.1
You are getting the SyntaxError. That happens because your code is being parsed before Babel can intercept it and convert.
If you want to make async functions work in your first file, you should require this entire file after have registered its hook.
Create a new file start.js with the following
require('babel-register');
require('./index');
Your code in index.js can use async functions, but you can't do it in the start.js.
Also note, that you don't need to read .babelrc by yourself. Babel will do it for you by default.
Contents of .babelrc looks like this
{
"presets": [
"es2015",
"stage-3"
],
"plugins": [
[
"transform-runtime",
{
"polyfill": false,
"regenerator": true
}
]
]
}
