I have a working website on my machine. Next can run it in the development mode and also build in the production one. But the problem is that on the server's machine it raises an error:
> Build error occurred
TypeError: Cannot destructure property 'serverRuntimeConfig' of 'next_config__WEBPACK_IMPORTED_MODULE_1___default(...)(...)' as it is undefined.
at Object.aorh (/home/MyInspire-ph.ru-v4/.next/server/pages/
Package version is the same, and it does work on my machine. How can I fix it?
Here's my config file
const path = require('path');
const { PHASE_DEVELOPMENT_SERVER } = require('next/constants');
module.exports = phase => {
return {
trailingSlash: true,
images: {
domain: ['localhost'],
},
publicRuntimeConfig: {
dev: phase === PHASE_DEVELOPMENT_SERVER,
},
serverRuntimeConfig: {
rootDir: __dirname.replace(/\\/g, '/'),
telegram: {
token: 'sometoken',
usersFile: 'somefile',
},
},
webpack: config => {
config.resolve.alias['#sass'] = path.resolve(__dirname, 'sass');
return config;
},
};
};

It seems that vite does not do automatic polyfills anymore - vite 4.0.0
How do you guys go about this? I have tried multiple variations of what I could find over the internet and none of them seems to be solid.

I encountered the same issue "cannot be marked as external" when working with the bip39 package and getting error because of buffer not defined. I tried many stuffs so not sure how what I solved, but here is my configuration (working with svelteKit):
In vite.config.js:
import { sveltekit } from '#sveltejs/kit/vite';
import type { UserConfig } from 'vite';
const config: UserConfig = {
plugins: [sveltekit()],
resolve: {
alias: {
// polyfills
Buffer: 'vite-compatible-readable-buffer',
stream: 'vite-compatible-readable-stream',
util: 'rollup-plugin-node-polyfills/polyfills/util',
}
}
};
export default config;
In layout.ts:
import { Buffer as BufferPolyfill } from 'buffer'
declare var Buffer: typeof BufferPolyfill;
globalThis.Buffer = BufferPolyfill
In app.html:
<script>
/**
* this is a hack for error: global is not defined
*/
var global = global || window
</script>
I hope it helps. I'm new to svelte and I don't 100% know what I'm doing :p
I have recently migrated from CRA to Vite. Everything went smooth, yet the build script is throwing an error.
Seems to be a RollupError
Could not resolve "../internals/window" from "../internals/window?commonjs-external"
When I remove the define object from my config, the build succeeds yet the dev server stops working
I am using the vite 4
here is my config
import { defineConfig } from "vite";
import react from "#vitejs/plugin-react";
import viteTsconfigPaths from "vite-tsconfig-paths";
import svgrPlugin from "vite-plugin-svgr";
// https://vitejs.dev/config/
export default defineConfig(({ command, mode }) => {

define: {
global: "window"
},
server: {

},
envPrefix: "REACT_APP_",
};
});
I use the following the bypass the issue, got the solution from here: https://dev.to/lico/issues-that-i-encountered-and-how-to-deal-with-them-while-migrating-from-cra-to-vite-51pg
define: {

In cypress.json file i have the following code
{
"baseUrl": "test",
"ignoreTestFiles": [],
"viewportHeight": 768,
"viewportWidth": 1024,
"video": false,
"env": { "email": "test#email.com", "password": "password" }
}
When i am trying to access it by calling Cypress.env('password') it shows undefined in console log when printing it, what is the issues.
const password: string = Cypress.env('password')
describe("Login to the application", () => {
beforeEach(() => {
cy.visit("/");
});
it.only("user should login successfully", () => {
console.log(Cypress.env('email')). --- undefined
loginPage.login(email, password);
cy.url().should("include", "/wallet");
});
My mistake for not knowing or not checking the location of my cypress.json file, moved it to the top cypress folder and value is shown properly.
In my Projekt (Version 10.xx) the cypress.config.ts must be in the root path not in the cypress folder. You can generate the config with the UI, to get it on the right location:
Settings > Project settings > cypress.config.ts
UPDATE for CYPRESS V10.
Extending #Artjom Prozorov answer,
Now in the newer version the cypress.json naming convention is deprecated.
So, we have to use cypress.config.ts as file name for configuration.
sample of file content given below.
import { defineConfig } from "cypress";
export default defineConfig({
e2e: {
specPattern: "src/**/*.cy.{js,jsx,ts,tsx}",
baseUrl: "http://localhost:3001",
trashAssetsBeforeRuns: false,
viewportWidth:1920,
viewportHeight:1080,
slowTestThreshold: 1000,
// watchForFileChanges : false,
env: {
apiUrl : "http://localhost:3000",
commandDelay: 100,
password: 'here it is'
},
reporter: 'mochawesome',
reporterOptions: {
reportDir: 'cypress/reports',
overwrite: false,
html: true,
json: false
},
setupNodeEvents(on, config) {
config.env.sharedSecret =
process.env.NODE_ENV === 'development' ? 'itsDev' : 'itsLocal'
return config
}
},
component: {
devServer: {
framework: "create-react-app",
bundler: "webpack"
}
}
});
NOTE : this cypress.config.ts must be inside the cypress directory.
I wanted to add custom entries to Next.js Webpack config to run them directly with chrome.runtime.executeScript for my browser extension. previously in CRA I could just add entries and remove splitChunks and runtimeChunk optimizations and it'd run without a problem but now in Next.js, Webpack builds them as a webpackChunk and they depend on main.js and I can't run them using chrome.runtime.executeScript.
Here's my webpack config in next.config.js:
webpack(config) {
config.module.rules.push({
test: /\.svg$/,
use: ["#svgr/webpack"],
});
if (config.target === "web" && config.mode === "production") {
config.optimization.splitChunks = {
cacheGroups: {
default: false,
},
};
config.optimization.runtimeChunk = false;
config.output = {
...config.output,
filename: "static/chunks/[name].js",
};
// Setting entries and return config
return Object.assign({}, config, {
entry: () => {
return config.entry().then((entry) => {
const newEntry = {
...entry,
background: "./src/browser-scripts/background.ts",
getMetas: "./src/browser-scripts/getMetas.ts",
};
return newEntry;
});
},
});
}
return config;
}
I am using the npm modules grunt env and load-grunt-config in my project. grunt env handles environment variables for you, while load-grunt-config handles, well, loads the grunt configuration for you. You can put your tasks into other files, then load-grunt-config will bundle them up and have grunt load & consume them for you. You can also make an aliases.js file, with tasks you want to combine together into one task, running one after another. It's similar to the grunt.registerTask task in the original Gruntfile.js. I put all my grunt tasks inside a separate grunt/ folder under the root folder with the main Gruntfile, with no extra subfolders, as suggested by the load-grunt-config README.md on Github. Here is my slimmed-down Gruntfile:
module.exports = function(grunt) {
'use strict';
require('time-grunt')(grunt);
// function & property declarations
grunt.initConfig({
pkg: grunt.file.readJSON('package.json')
});
require('load-grunt-config')(grunt, {
init: true,
loadGruntConfig: {
scope: 'devDependencies',
pattern: ['grunt-*', 'time-grunt']
}
});
};
In theory, setting all these files up the correct way for load-grunt-config to load should be exactly the same as just having a Gruntfile.js. However, I seem to have run into a little snag. It seems the environment variables set under the env task do not get set for the subsequent grunt tasks, but are set by the time node processes its tasks, in this case an express server.
grunt env task:
module.exports = {
// environment variable values for developers
// creating/maintaining site
dev: {
options: {
add: {
NODE_ENV: 'dev',
MONGO_PORT: 27017,
SERVER_PORT: 3000
}
}
}
};
grunt-shell-spawn task:
// shell command tasks
module.exports = {
// starts up MongoDB server/daemon
mongod: {
command: 'mongod --bind_ip konneka.org --port ' + (process.env.MONGO_PORT || 27017) + ' --dbpath C:/MongoDB/data/db --ipv6',
options: {
async: true, // makes this command asynchronous
stdout: false, // does not print to the console
stderr: true, // prints errors to the console
failOnError: true, // fails this task when it encounters errors
execOptions: {
cwd: '.'
}
}
}
};
grunt express task:
module.exports = {
// default options
options: {
hostname: '127.0.0.1', // allow connections from localhost
port: (process.env.SERVER_PORT || 3000), // default port
},
prod: {
options: {
livereload: true, // automatically reload server when express pages change
// serverreload: true, // run forever-running server (do not close when finished)
server: path.resolve(__dirname, '../backend/page.js'), // express server file
bases: 'dist/' // watch files in app folder for changes
}
}
};
aliases.js file (grunt-load-config's way of combining tasks so they run one after the other):
module.exports = {
// starts forever-running server with "production" environment
server: ['env:prod', 'shell:mongod', 'express:prod', 'express-keepalive']
};
part of backend/env/prod.js (environment-specific Express configuration, loaded if NODE_ENV is set to "prod", modeled after MEAN.JS):
'use strict';
module.exports = {
port: process.env.SERVER_PORT || 3001,
dbUrl: process.env.MONGOHQ_URL || process.env.MONGOLAB_URI || 'mongodb://konneka.org:' + (process.env.MONGO_PORT || 27018) + '/mean'
};
part of backend/env/dev.js (environment-specific Express configuration for dev environment, loaded if the `NODE_ENV variable is not set or is set to "dev"):
module.exports = {
port: process.env.SERVER_PORT || 3000,
dbUrl: 'mongodb://konneka.org:' + (process.env.MONGO_PORT || 27017) + '/mean-dev'
};
part of backend/page.js (my Express configuration page, also modeled after MEAN.JS):
'use strict';
var session = require('express-session');
var mongoStore = require('connect-mongo')(session);
var express = require('express');
var server = express();
...
// create the database object
var monServer = mongoose.connect(environ.dbUrl);
// create a client-server session, using a MongoDB collection/table to store its info
server.use(session({
resave: true,
saveUninitialized: true,
secret: environ.sessionSecret,
store: new mongoStore({
db: monServer.connections[0].db, // specify the database these sessions will be saved into
auto_reconnect: true
})
}));
...
// listen on port related to environment variable
server.listen(process.env.SERVER_PORT || 3000);
module.exports = server;
When I run grunt server, I get:
$ cd /c/repos/konneka/ && grunt server
Running "env:prod" (env) task
Running "shell:mongod" (shell) task
Running "express:prod" (express) task
Running "express-server:prod" (express-server) task
Web server started on port:3000, hostname: 127.0.0.1 [pid: 3996]
Running "express-keepalive" task
Fatal error: failed to connect to [konneka.org:27018]
Execution Time (2014-08-15 18:05:31 UTC)
loading tasks 38.3s █████████████████████████████████ 79%
express-server:prod 8.7s ████████ 18%
express-keepalive 1.2s ██ 2%
Total 48.3s
Now, I can't seem to get the database connected in the first place, but ignore that for now. Notice that the server is started on port 3000, meaning that during execution of the grunt express:prod task, SERVER_PORT is not set so the port gets set to 3000. There are numerous other examples like this, where an environment variable is not set so my app uses the default. However, notice that session tries to connect to the database on port 27018 (and fails), so MONGO_PORT does get set eventually.
If I had just tried the grunt server task, I could chalk it up to load-grunt-config running the tasks in parallel instead of one after the other or some other error, but even when I try the tasks one-by-one, such as running grunt env:prod shell:mongod express-server:prod express-keepalive, I get similar (incorrect) results, so either grunt or grunt env run the tasks in parallel, as well, or something else is going on.
What's going on here? Why are the environment variables not set correctly for later grunt tasks? When are they eventually set, and why then rather than some other time? How can I make them get set for grunt tasks themselves rather than after, assuming there even is a way?
The solution is rather obvious once you figure it out, so let's start at the beginning:
The problem
You're using load-grunt-config to load a set of modules (objects that define tasks) and combine them into one module (object) and pass it along to Grunt. To better understand what load-grunt-config is doing, take a moment to read through the source (it's just three files). So, instead of writing:
// filename: Gruntfile.js
grunt.initConfig({
foo: {
a: {
options: {},
}
},
bar: {
b: {
options: {},
}
}
});
You can write this:
// filename: grunt/foo.js
module.exports = {
a: {
options: {},
}
}
// filename: grunt/bar.js
module.exports = {
b: {
options: {},
}
}
// filename: Gruntfile.js
require('load-grunt-config')(grunt);
Basically, this way you can split up a Grunt configuration into multiple files and have it be more "maintainable". But what you'll need to realize is that these two approaches are semantically equivalent. That is, you can expect them to behave the same way.
Thus, when you write the following*:
(* I've reduced the problem in an attempt to make this answer a bit more general and to reduce noise. I've excluded things like loading the tasks and extraneous option passing, but the error should still be the same. Also note that I've changed the values of the environment variables because the default was the same as what was being set.)
// filename: grunt/env.js
module.exports = {
dev: {
options: {
add: {
// These values are different for demo purposes
NODE_ENV: 'dev',
MONGO_PORT: 'dev_mongo_port',
SERVER_PORT: 'dev_server_port'
}
}
}
};
// filename: grunt/shell.js
module.exports = {
mongod: {
command: 'mongod --port ' + (process.env.MONGO_PORT || 27017)
}
};
// filename: grunt/aliases.js
module.exports = {
server: ['env:prod', 'shell:mongod']
};
// filename: Gruntfile.js
module.exports = function (grunt) {
require('load-grunt-config')(grunt);
};
You can consider the above the same as below:
module.exports = function (grunt) {
grunt.initConfig({
env: {
dev: {
options: {
add: {
NODE_ENV: 'dev',
MONGO_PORT: 'dev_mongo_port',
SERVER_PORT: 'dev_server_port'
}
}
}
},
shell: {
mongod: {
command: 'mongod --port ' + (process.env.MONGO_PORT || 27017)
}
}
});
grunt.registerTask('server', ['env:dev', 'shell:mongod']);
};
Now do you see the problem? What command do you expect shell:mongod to run? The correct answer is:
mongod --port 27017
Where what you want to be executed is:
mongo --port dev_mongo_port
The problem is that when (process.env.MONGO_PORT || 27017) is evaluated the environment variables have not yet been set (i.e. before the env:dev task has been run).
A solution
Well let's look at a working Grunt configuration before splitting it across multiple files:
module.exports = function (grunt) {
grunt.initConfig({
env: {
dev: {
options: {
add: {
NODE_ENV: 'dev',
MONGO_PORT: 'dev_mongo_port',
SERVER_PORT: 'dev_server_port'
}
}
}
},
shell: {
mongod: {
command: 'mongod --port ${MONGO_PORT:-27017}'
}
}
});
grunt.registerTask('server', ['env:dev', 'shell:mongod']);
};
Now when you run shell:mongod, the command will contain ${MONGO_PORT:-27017} and Bash (or just sh) will look for the environment variable you would have set in the task before it (i.e. env:dev).
Okay, that's all well and good for the shell:mongod task, but what about the other tasks, Express for example?
You'll need to move away from environment variables (unless you want to set them up before invoking Grunt. Why? Take this Grunt configuration for example:
module.exports = function (grunt) {
grunt.initConfig({
env: {
dev: {
options: {
add: {
NODE_ENV: 'dev',
MONGO_PORT: 'dev_mongo_port',
SERVER_PORT: 'dev_server_port'
}
}
}
},
express: {
options: {
hostname: '127.0.0.1'
port: (process.env.SERVER_PORT || 3000)
},
prod: {
options: {
livereload: true
server: path.resolve(__dirname, '../backend/page.js'),
bases: 'dist/'
}
}
}
});
grunt.registerTask('server', ['env:dev', 'express:prod']);
};
What port will the express:prod task configuration contain? 3000. What you need is for it to reference the value you've defined in the above task. How you do this is up to you. You could:
Separate the env configuration and reference its values
module.exports = function (grunt) {
grunt.config('env', {
dev: {
options: {
add: {
NODE_ENV: 'dev',
MONGO_PORT: 'dev_mongo_port',
SERVER_PORT: 'dev_server_port'
}
}
}
});
grunt.config('express', {
options: {
hostname: '127.0.0.1'
port: '<%= env.dev.options.add.SERVER_PORT %>'
}
});
grunt.registerTask('server', ['env:dev', 'express:prod']);
};
But you'll notice that the semantics of the env task don't hold up here due to it no longer representing a task's configuration. You could use an object of your own design:
module.exports = function (grunt) {
grunt.config('env', {
dev: {
NODE_ENV: 'dev',
MONGO_PORT: 'dev_mongo_port',
SERVER_PORT: 'dev_server_port'
}
});
grunt.config('express', {
options: {
hostname: '127.0.0.1'
port: '<%= env.dev.SERVER_PORT %>'
}
});
grunt.registerTask('server', ['env:dev', 'express:prod']);
};
Pass grunt an argument to specify what config it should use
Have multiple configuration files (e.g. Gruntfile.js.dev and Gruntfile.js.prod) and rename them as needed
Read a development configuration file (e.g. grunt.file.readJSON('config.development.json')) if it exists and fall back to a production configuration file if it doesn't exist
Some better way not listed here
But all of the above should achieve the same end result.
This seems to be the essence of what you are trying to do, and it works for me. The important part was what I mentioned in my comment -- chaining the environment task before running the other tasks.
Gruntfile.js
module.exports = function(grunt) {
// Do grunt-related things in here
grunt.loadNpmTasks('grunt-env');
grunt.initConfig({
env: {
dev: {
PROD : 'http://production.server'
}
}
});
grunt.registerTask('printEnv', 'prints a message with an env var', function() { console.log('Env var in subsequent grunt task: ' + process.env.PROD) } );
grunt.registerTask('prod', ['env:dev', 'printEnv']);
};
Output of grunt prod
Running "env:dev" (env) task
Running "printEnv" task
Env var in subsequent grunt task: http://production.server
Done, without errors.
