It’s not unusual to have our application code rely on one or more environment variables . Different pieces of information, like for example, API keys, API URLs, different configuration parameters, or environment metadata, are just some of the things that our application might need in order to work as expected.
Environment variables can be used with all three project applications that get shipped with every Webiny project:
- API (
apps/api
)
- Admin (
apps/admin
)
- Website (
apps/website
)
Upon adding new environment variables, we use the following naming convention:
WEBINY_{APP_NAME}_{VARIABLE_NAME}
For example, in order to inject MY_CUSTOM_ENV_VAR
variable into all three application, we’d define the following three environment variables:
WEBINY_API_MY_CUSTOM_ENV_VAR=...
WEBINY_ADMIN_MY_CUSTOM_ENV_VAR=...
WEBINY_WEBSITE_MY_CUSTOM_ENV_VAR=...
Note that, upon accessing added environment variables in the application code, you need to specify variable’s full name, including the WEBINY_{APP_NAME}_
prefix:
// In the API application code:
const myCustomEnvVar = process.env["WEBINY_API_MY_CUSTOM_ENV_VAR"];
// In the Admin application code:
const myCustomEnvVar = process.env["WEBINY_ADMIN_MY_CUSTOM_ENV_VAR"];
// In the Website application code:
const myCustomEnvVar = process.env["WEBINY_WEBSITE_MY_CUSTOM_ENV_VAR"];

For development purposes, the recommended way to do it would be via the .env
file, located in your project root.
When you set up a brand new Webiny project, the content of the file might look similar to the following:
# The region into which your project will be deployed.AWS_REGION=eu-central-1
# Needed for project deployment.PULUMI_CONFIG_PASSPHRASE=9f174eea6ec6148dc1467s59b1112591PULUMI_SECRETS_PROVIDER=passphrase
WEBINY_API_MY_CUSTOM_ENV_VAR=some-random-value
From there, we can easily add additional environment variables, like we did with the WEBINY_API_MY_CUSTOM_ENV_VAR
.

Apart from setting them via the shown .env
file, environment variables can also be set using a terminal of your choice, and a command that’s available on your operating system.
For example, on Linux or MacOS, you can use the export command:
export AWS_PROFILE=my-profile
On Windows, you can utilize the set and setx
commands, for example:
setx AWS_PROFILE my-profile
This approach can be used both in development and CI/CD environments, although in case of the latter, using built-in methods for securely storing environment variables is recommended.

Different CI/CD providers offer different options when it comes to setting environment variables. For example, GitHub Actions enable this via repository secrets
. On the other hand, if using AWS CodeBuild
, you can use the AWS CodePipeline
service.
Make sure to read the relevant documentation for best practices around how to properly set environment variables in your CI/CD provider.

In order to provide the best possible debugging experience, and at the same time, maintain a strong security posture, Webiny uses the DEBUG
environment variable to determine what information needs to be revealed in case one or more errors were thrown in the application runtime.
By default, the DEBUG
environment variable is set to true
, via the .env
file located in your project root. For development purposes, this can useful as you’ll get to see full error reports whenever an error has been returned from for example the GraphQL API, or maybe even in your React application code.
On the other hand, for some pre-production and production environments, most probably you will want to not have this variable set to true
, as in some cases, full error reports might reveal sensitive data, and may pose a security vulnerability.
In the following text, we cover a couple of key features that are available while the DEBUG
flag is set to true
.
Backend Error Reporting![anchor](data:image/svg+xml;base64,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)
In case of a backend error, for example, an error in a GraphQL resolver function, by default, the client that issued the request will receive the following error response:
{
"error": {
"name": "Error",
"message": "Internal Sever Error"
}
}
As mentioned, the reason for the obscurity is primarily security, as we want to avoid potential leaking of sensitive information to the public.
On the other hand, for development purposes, setting the DEBUG
environment variable to true
, will force the backend to return something like the following:
{
"error": {
"name": "Error",
"message": "Unknown type\"Stringgg\". Did you mean \"String\"?",
"stack": "Error: Unknown type \"Stringgg\". Did you mean \"String\"?\n at p (/var/task/handler.js:15:52587)\n at x (/var/task/handler.js:45:166906)\n at fe (/var/task/handler.js:126:504732)\n at Ee (/var/task/handler.js:126:514113)\n at t.createGraphQLSchema (/var/task/handler.js:57:373)\n at handle (/var/task/handler.js:45:189370)\n at /var/task/handler.js:45:187469\n at new Promise (<anonymous>)\n at i (/var/task/handler.js:45:187419)\n at /var/task/handler.js:45:187592"
}
}
You must redeploy your backend project application after updating the environment variables. Otherwise, the change will not be reflected.

The DEBUG
environment variable can also be used within your frontend (React) applications.
If set to true
, all errors detected in the application runtime will be presented within a clear error report, with all of the relevant information like the error message and a complete stack trace:

The WEBINY_ENABLE_VERSION_HEADER
environment variable is used to add the Webiny version header to all GraphQL response headers.
By default, version headers are not set into the response headers. If you want the version headers to be included, you must set the environment variable to true
.
Only the true
word will have effect. If you set it to anything else, WEBINY_ENABLE_VERSION_HEADER
will be considered as false
/ not set.
WEBINY_ENABLE_VERSION_HEADER=true
When the environment variable is set to true it will add the x-webiny-version
header. Which looks like this:
x-webiny-version: 5.21.0

Behind the scenes, Webiny CLI uses the dotenv
.env
file. Note that the values that are defined in the .env
file will not get assigned as environment variables if they were already assigned in the running process (e.g. via terminal, or as a secret in your CI/CD workflow). This is the default behaviour of the dotenv
library.
