Quasar App Extension qenv
quasar-app-extension-qenv is a CLI App Extension
for Quasar Framework. It is a stand-alone environment-to-browser parser and aggregator.
Now compatible with Quasar v2 beta
v1.1.0 now supports expanding environmental variables put inside your
.quasar.env.json
file!
Demo
Can be found here.
Install
quasar ext add @quasar/qenv
Quasar CLI will retrieve it from NPM and install the extension.
Prompts
-
"What name would you like to use for your Common Root Object ('none' means to not use one)?" The default is "none" The "common root object" means off of "process.env" you will have a named object, basically for organization purposes.
-
"For security, would you like your .quasar.env.json file automatically added to .gitignore?" The default is "true" (yes) If you say "yes" to this question, then your .quasar.env.json file will automatically be inserted into the .gitignore. For security purposes, because you may have sensitive data in your
.quasar.env.json
file, you should not keep it in a repository.
Accessing the Data
Any data in a .quasar.env.json
will be placed in process.env
at the browser level. DO NOT console.log(process.env)
as you will not see anything. For security purposes Quasar abstracts this away from prying eyes. If your env variable is PORT
, then you can console.log(process.env.PORT)
to see the results.
Tips
If you specified a common root object, say MyData
, then the data will be placed at process.env.MyData
.
Format
The format of the .quasar.env.json
is as follows:
{
"development": {
"ENV_TYPE": "Running Development",
"ENV_DEV": "Development",
"SHELL: "${SHELL}"
},
"production": {
"ENV_TYPE": "Running Production",
"ENV_PROD": "Production",
"SHELL: "${SHELL}"
},
"test": {
"ENV_TYPE": "Running Test",
"ENV_Test": "Test",
"SHELL: "${SHELL}"
}
}
This is the default that is installed and you will need to modify it to fit your needs.
You can add as many environments as needed (top-level keys). You are not restricted to the development
, production
and test
that come by default. And, you can add as many variables under those environment types as you like.
Using Environment Variables
Environment variable are accessed like this: $MyVar
or ${MyVar}
. If it exists, then it will be expanded.
Let's use the test
object from above to expand it out for something that would be used in production:
"test": {
NODE_ENV: "test",
BASIC: "basic",
BASIC_EXPAND: "$BASIC",
MACHINE: "machine_env",
MACHINE_EXPAND: "$MACHINE",
UNDEFINED_EXPAND: "$UNDEFINED_ENV_KEY",
ESCAPED_EXPAND: "\$ESCAPED",
MONGOLAB_DATABASE: "heroku_db",
MONGOLAB_USER: "username",
MONGOLAB_PASSWORD: "password",
MONGOLAB_DOMAIN: "abcd1234.mongolab.com",
MONGOLAB_PORT: 12345,
MONGOLAB_URI: "mongodb://${MONGOLAB_USER}:${MONGOLAB_PASSWORD}@${MONGOLAB_DOMAIN}:${MONGOLAB_PORT}/${MONGOLAB_DATABASE}",
MONGOLAB_USER_RECURSIVELY: "${MONGOLAB_USER}:${MONGOLAB_PASSWORD}",
MONGOLAB_URI_RECURSIVELY: "mongodb://${MONGOLAB_USER_RECURSIVELY}@${MONGOLAB_DOMAIN}:${MONGOLAB_PORT}/${MONGOLAB_DATABASE}",
WITHOUT_CURLY_BRACES_URI: "mongodb://$MONGOLAB_USER:$MONGOLAB_PASSWORD@$MONGOLAB_DOMAIN:$MONGOLAB_PORT/$MONGOLAB_DATABASE",
WITHOUT_CURLY_BRACES_USER_RECURSIVELY: "$MONGOLAB_USER:$MONGOLAB_PASSWORD",
WITHOUT_CURLY_BRACES_URI_RECURSIVELY: "mongodb://$MONGOLAB_USER_RECURSIVELY@$MONGOLAB_DOMAIN:$MONGOLAB_PORT/$MONGOLAB_DATABASE"
}
Specifying environment
So, how is this accessed?
You will need to modify your package.json
in the scripts area. Let's take a look at an example:
"scripts": {
"dev": "QENV=development quasar dev",
"test-dev": "QENV=test quasar dev",
"combined": "QENV=development+test quasar dev",
"build": "QENV=production quasar build"
},
Basically, you need to set the QENV environment variable for Node. You specifiy the key that you want for the propgated data.
QEnv with Windows
There are several ways to set the QENV enviironment variable on Windows.
CMD
"dev": "set QENV='development' & quasar dev"
PowerShell (VS Code default)
"dev": "$env:QENV='development'; quasar dev"
...and for a solution that works for either:
Many thanks to NicksonYap for the following information:
QEnv will work on Windows by additionally installing cross-env.
npm install --save-dev cross-env
or
yarn add --dev cross-env
Then, in package.json:
"dev": "cross-env QENV=development quasar dev"
QEnv with Docker
QEnv will work with Docker by using the following syntax to inject your QENV variable into Node:
$ sudo docker run [...] -e QENV="development"
Chaining environments
Look at the combined
script. Absolutely, you can chain two or more configurations together. When doing this, if there is any conflicting variables, the last one in wins.
In other words:
"combined": "QENV=development+test quasar dev",
will give different results than:
"combined": "QENV=test+development quasar dev",
And to be clear, you would do the following to run it:
# npm
npm run combined
# or
# yarn
yarn combined
Uninstall
quasar ext remove @quasar/qenv
