resolve-vars
Retrieving variables stored in a remote system can be painful, so resolve-vars
makes it simple to get and set values stored in Consul.
Installation
$ yarn add resolve-vars
or if using npm
:
$ npm install resolve-vars --save
Usage
Initialization
Creating an instance of a variable resolver is simple:
const Resolver = require('resolve-vars');
const resolver = new Resolver();
Retrieving a single value
Retrieving a value is an asynchronous action, as such, get
returns a promise
that resolves to the retrieved value if one existed.
resolver.get('foo/bar/baz')
.then((val) => {
console.log(`value is: ${val}`);
});
Resolving multiple values at once
In some situations, you'll want to resolve variables in bulk, which is why
task
exists. task
returns a promise that resolves to the variables'
values (if found).
resolver.task([ 'foo/bar/baz', 'bizz/buzz' ])()
.then((vals) => {
console.log(vals);
});
This is especially useful in situations where you want to resolve a set of variables on startup, such as in Gulp.
gulp.task('resolve-vars', resolver.task([ 'foo/bar/baz', 'bizz/buzz' ]));
Setting the value for a variable
Setting a value is as simple as retrieving one with get. Set also returns a promise that resolves once the value is succcessfuly set, otherwise it rejects.
resolver.set('bizz/buzz', 'super')
.then(() => {
console.log('successfully set value')
}).catch((err) => {
console.log('failed to set value: ' + err);
});
