npm install --global as-a
You can run this tool without installing it
npx as-a [section name] [command ...]
You can also install this tool locally as a dev dependency. In that case, it will start faster than using npx as-a ...
without an install.
npm i -D as-a
npx as-a [section name] [command ...]
Create a file in your user's home directory .as-a.ini
touch ~/.as-a.ini
Create separate sections for groups of environment settings. For example
; this is a test section
[test]
name=test
why=just because
Now you can run any command (with arguments) and add the section as environment variables.
$ npm run env | grep why
--- nothing ----
$ as-a test npm run env | grep why
why=just because
Recommended to keep private settings for DEV urls, secrets, etc.
You can even use settings from multiple groups of settings using comma-separated list
[DEV]
username=tester
password=pass1234
[redis]
REDIST_HOST=localhost:4534
as-a DEV,redis node index.js
A good practice for me was naming a section after the folder name. For example, if the INI file has the following:
[my-server-repo]
DB_USERNAME=user1234
Then we can inject the variables by running in the folder "my-server-repo" using "."
/my/folders/my-server-repo: $ as-a . node ./start
# injects section "my-server-repo"
Read how to run a Redis server inside the Docker container using as-a
in this
gist.
To better separate secrets from user home folder, you can place the .as-a.ini
file
into subfolder ~/.as-a/.as-a.ini
.
Sometimes it makes sense to have a local file .as-a.ini
in the project's
folder (current working directory) with settings that should override
any section from the home folder's .as-a.ini
. Just create such file and use
it.
Tip: when using a local .as-a.ini
file make sure to git ignore .as-a.ini
to avoid accidentally committing this file to the repository.
Resolution
- local
.as-a.ini
+~/.as-a.ini
=> combination, local file wins - local
.as-a.ini
+~/.as-a/.as-a.ini
=> combination, local file wins - local
.as-a.ini
=> just this file - otherwise an error is thrown
Just like you can use multiple sections, the INI sections themselves can have multiple aliases. For example, you can have the same section under two or more names to avoid duplication:
; you can use these environment variables by using name "user" or "personal"
[user, personal]
NAME=...
ID=...
These two commands are equivalent
$ as-a user ...
$ as-a personal ...
To see the version of the installed as-a
run it without arguments
$ as-a
as-a@2.1.0
> Runs a given command with additional environment settings
> for simple local development
use : as-a <env settings name> [command with options]
example: as-a DEV node client.js --request foo
Loads the specified settings sections and returns merged object
const {getSettings} = require('as-a')
// load sections [db] and [app]
getSettings('db,app') // {DB_HOST:...,USERNAME:...}
If the settings are not applied correctly, run the command with DEBUG=as-a
variable
$ DEBUG=as-a as-a name command arguments ...
as-a loading sections +1ms [ 'name' ]
as-a running "npx" with extra env keys +0ms [ 'USERNAME', 'PASSWORD' ]
