I'm using Next.js with Vercel. This is my .env.local file:
# Created by Vercel CLI
VERCEL="1"
VERCEL_ENV="development"
VERCEL_URL=""
VERCEL_GIT_PROVIDER=""
VERCEL_GIT_REPO_SLUG=""
VERCEL_GIT_REPO_OWNER=""
VERCEL_GIT_REPO_ID=""
VERCEL_GIT_COMMIT_REF=""
VERCEL_GIT_COMMIT_SHA=""
VERCEL_GIT_COMMIT_MESSAGE=""
VERCEL_GIT_COMMIT_AUTHOR_LOGIN=""
VERCEL_GIT_COMMIT_AUTHOR_NAME=""
I have a component that is trying to access: process.env.NEXT_PUBLIC_VERCEL_ENV to make sure it is on development environment.
This is what I'm getting when running npm run dev.
Logs from the server:
The logs above make perfect sense. Since it's running on the local server to render the pages.
But when my client code tries to do the same, I'm getting:
This is how I'm trying to acess it:
console.log(`process.env.NEXT_PUBLIC_VERCEL_ENV: ${JSON.stringify(process.env.NEXT_PUBLIC_VERCEL_ENV)}`);
console.log(`process.env.VERCEL_ENV: ${JSON.stringify(process.env.VERCEL_ENV)}`);
On client, the VERCEL_ENV should be undefined, but NEXT_PUBLIC_VERCEL_ENV should be development, right?
What could be happening?
UPDATE
I even tried to add NEXT_PUBLIC_VERCEL_ENV="development" to the .env.local file. But so far, the result is the same.
NEXT_PUBLIC_VERCEL_ENV="development"
You will have access to this everywhere (in the browser and Server).
VERCEL_ENV="development"
You only have access to this in the server, in the browser it will show undefined.
Please note after you add or make any changes in the .env.local file you have to restart your server otherwise it will show undefined if you console.log the variables.
Make sure Automatically expose System Environment Variables is checked in your Project Settings.

I want Drupal to recognize my new twig files. Trying to clear the cache with the
drush cr
command gives me a success message. So does manually clicking on "Flush all caches" from the menu. But my new twig files are not being recognized. I was able to clear caches for weeks perfectly fine and it recognized twig files until now. I am using ddev to run my server. I have stopped and restarted the server. Restarted docker. I am using development.services.yml, not services.yml, which from my research I believe is correct. I am also exporting my settings.local.php from my settings.php.
I would like for Drupal to recognize my twig files. Neither clearing the cache by command line with
or manually works. No part of the configuration was changed it just stopped working suddenly.
Most probably, it’s related with permissions.
Resetting permissions, perhaps like described in
After drupal update site throws HTTP ERROR 500
might work,
According to the Serverless documentation, I should be able to define params within the dashboard/console. But when I navigate there, the inputs are disabled:
I've tried following the instructions to update via CLI, with: serverless deploy --param="domain=myapp.com" --param="key=value". The deploy runs successfully (I get a ✔ Service deployed to... message with no errors), but nothing appears in my dashboard. Likewise, when I run a command to check whether there are any params stored: serverless param list, I get
Running "serverless" from node_modules
No parameters stored
Passing param flags will not upload the parameters to Dashboard/Console, it will only expose them in your configuration so you can access them with ${param:<param-name>}. To my best knowledge, it is not possible to set Dashboard parameters with CLI, you need to set them manually via UI.
It was a permissions problem. The owner of the account updated the permissions and I was able to update the inputs.
I am trying to install Weblogic adminserver as windows service but getting "Input too long" error while executing the install script.
I have struggled a lot in this issue and finally got the way to register AdminServer and Nodemanager as windows service for Weblogic. Below are the steps and issues faced with the progress:
To register weblogic AdminServer as windows server first need to create a script which will contain values like oracle home, java home etc. Below is the script I have used to install the service:
`
echo off
SETLOCAL
set MW_HOME=C:\Oracle\Middleware\Oracle_Home
set DOMAIN_NAME=osb_domain
set USERDOMAIN_HOME=C:\Oracle\Middleware\Oracle_Home\user_projects\domains\osb_domain
set SERVER_NAME=AdminServer
set WL_HOME=C:\Oracle\Middleware\Oracle_Home\wlserver
set PRODUCTION_MODE=true
set JAVA_OPTIONS=-Dweblogic.Stdout="%USERDOMAIN_HOME%\stdout.txt" -Dweblogic.Stderr="%USERDOMAIN_HOME%\stderr.txt"
set WLS_USER=weblogic
set WLS_PW=Password123
set MEM_ARGS=-Xms1024m -Xmx1024m
call "C:\Oracle\Middleware\Oracle_Home\user_projects\domains\osb_domain\bin\setDomainEnv.cmd"
call "C:\Oracle\Middleware\Oracle_Home\wlserver\server\bin\installSvc.cmd"
ENDLOCAL
`
By running this script I was not even able to install the windows service as it was throwing " Input is too long" error and the reason is windows char limitations. You might get confused by classpath and will try to resolve classpath but
the issue is with JAVA_OPTIONS values which is set by SetDomainEnv.txt is creating this issue.
I have modified the script like below and shorten the JAVA_OPTIONS values by calling SetDomainEnv.txt command just before setting JAVA_OPTIONS in the script.
This has overridden the lengthy value of JAVA_OPTIONS. Now I have succesfully installed the AdminServer as windows service.
`
echo off
SETLOCAL
set MW_HOME=C:\Oracle\Middleware\Oracle_Home
set DOMAIN_NAME=osb_domain
set USERDOMAIN_HOME=C:\Oracle\Middleware\Oracle_Home\user_projects\domains\osb_domain
set SERVER_NAME=AdminServer
set WL_HOME=C:\Oracle\Middleware\Oracle_Home\wlserver
set PRODUCTION_MODE=true
call "C:\Oracle\Middleware\Oracle_Home\user_projects\domains\osb_domain\bin\setDomainEnv.cmd"
set JAVA_OPTIONS=-Dweblogic.Stdout="%USERDOMAIN_HOME%\stdout.txt" -Dweblogic.Stderr="%USERDOMAIN_HOME%\stderr.txt"
set WLS_USER=weblogic
set WLS_PW=Password123
set MEM_ARGS=-Xms1024m -Xmx1024m
call "C:\Oracle\Middleware\Oracle_Home\wlserver\server\bin\installSvc.cmd"
ENDLOCAL `
Even the service is successfully installed, when I was starting it the service is stopped immediately and wasn't printing any logs as it was not connecting to AdminServer.
After a bit analysis I found that JAVA_OPTIONS values which I have overridden in my script is very much needed to invoke AdminServer.
I have run SetDomainEnv.txt in cmd prompt and copied thre JAVA_OPTIONS values.
As the service is already installed, I just copied the correct JAVA_OPTIONS values CMDLINE param in the windows service registry manually.
Server subsystem failed. Reason: A MultiException has 6 exceptions.
Server installed as Windows NT service with incorrect password for user weblogic. The password may have been changed since the server was installed as a Windows NT Service. Contact the Windows NT system administrator.
Note: No extra spaces or character is inserted in CMDLINE param.
Now everything is in place which is actually required to start the admin server. But when I start the service it is throwing some authentication error along with others in the adminserver.log file.
after a lot of analysis I found that is is not authentoication issue, the problem was with boot.properties file. boot. properties file was not read properly.
This answer is continuation of below one:
after a lot of analysis I found that is is not authentoication issue, the problem was with boot.properties file. boot. properties file was not read properly.
Now I would give some background- If the fusion middleware is installed as development mode the boot.properties files is created automatically inside Oracle_HOME\user_projects\domains\domainname\servers\AdminServer\security and if you look at this prop file you will find the password and username in encrypted mode.
If the fusion Middleware is installed as production Mode then everytime it will ask for password and username. to avoid this perform below steps:
manually create file under Oracle_HOME\user_projects\domains\domainname\servers\AdminServer\security\boot.properties like mention below:
username=weblogic
password=Password
Note: No spaces should be added and take care of file extension.
Now start weblogic from domain\bin\startWeblogic.cmd. This will encrypt you boot.properties file. check boot.proprties file if encrypted you are good to go.
Finally start the windows service whic is installed following above process. It should work fine.
=======================
About Node manager use installNodeMgrSvc from domain\bin. Again if you get input is too long error, you must shorten JAVA_OPTIONS and then carefully edit CMDLINE param in the windows registry.
I'm working on an app with vuejs frontend and nodejs backend. My frontend makes API https requests to the backend. I've started my projet with vue-cli and webpack.
I need to get the backend API url from env variable (BACKEND_URL).
Since i'm using webpack, I added this line to config/prod.env.js :
module.exports = {
NODE_ENV: '"production"',
-> BACKEND_URL: JSON.stringify(process.env.BACKEND_URL)
}
It works flawlessly in dev mode using webpack-dev-server. I pass the env var throught docker-compose file:
environment:
- BACKEND_URL=https://whatever:3000
But when I run build, I use nginx to serve the static files (but the problem is the same using visual studio code live server extension). I send BACKEND_URL env var the same way as before. The thing is now the process.env.BACKEND_URL is undefined in the app (but defined in the container)!! So I cant make backend http calls :(
I'm struggling finding the problem, please don't be rude with the responses. Thank you
They aren not "translated" during build time, this is what is happening with you. On a node environment, when you ask for process.env it will show all environment variables available in the system, that is true. But a web application does not have access to process.env when it is executing. You need a way to translate them during build time.
To achieve that you have to use DefinePlugin. It translates anything during build time and writes a magical string where this other thing was.
Using you own example:
module.exports = {
NODE_ENV: '"production"',
BACKEND_URL: JSON.stringify(process.env.BACKEND_URL)
}
If you do this during build time, without DefinePlugin, webpack won't know what to do with it, and it is going to be a simple string.
If you use DefinePlugin:
new webpack.DefinePlugin({
"process.env.BACKEND_URL": JSON.stringify(process.env.BACKEND_URL)
});
By doing this, you are allowing webpack to translate this during build time.
Give this a shot: https://www.brandonbarnett.io/blog/2018/05/accessing-environment-variables-from-a-webpack-bundle-in-a-docker-container/
If I'm understanding your problem correctly, you're serving a webpack bundle using nginx, and trying to access an environment variable from that bundle.
Unfortunately, it doesn't quite work that way. Your JS file has no access to the environment since it's a resource that has been delivered to the client. I've proposed a solution that also delivers those env variables alongside the bundle in a separate JS file that gets created on container start.
From VueJS Docs: https://cli.vuejs.org/guide/mode-and-env.html
Using Env Variables in Client-side Code
Only variables that start with VUE_APP_ will be statically embedded into the client bundle with webpack.DefinePlugin. You can access them in your application code:
console.log(process.env.VUE_APP_SECRET)
During build, process.env.VUE_APP_SECRET will be replaced by the corresponding value. In the case of VUE_APP_SECRET=secret, it will be replaced by "secret".
So in your case, the following should do the trick. I had the same problem once in my project, which I started with vue/cli and vue create project ...
VUE_APP_BACKEND_URL=https://whatever:3000
Not sure how to ask this question but would like to put it here and want to hear some suggestions.
So far, I use "DB_LINK" variable that has mongo database url in my config.json file. My Node app uses this variable to connect to the Mongo. But this DB_LINK also gets checked into git, which we dont want this to happen because we dont want to check in the passwords into git.
in my local development, I use local.json file that has all these configs and not check that file into git (in .gitignore entry). So it is fine making it work in my local dev environment, but the challenge is when Jenkins try to push the code to TEST, it has to pass testcases (it has to run test cases, so that time the DB_LINK value is needed) before deployment happens. so this is when I need this DB_LINK variable be passed from Jenkins.
Here is what I did so far ..
in Jenkins configurations, at the 'predefined parameters' I added DB_LINK=myMongoLink to parameters list.
but this value is not being handed over to my node app. Any suggestions on how to achieve what I am trying to achieve?
Ok. I figured this out. before the change, I used to pass a command from Jenkins to run my test cases like this
npm run test
but now,
DBLink=myDB npm run test
so the DBLink variable from here being handed over to the node app and was able to run the test cases. Before this change,
I used to pass this DBLink=myDB from a config file
