System
The System Aptitude provides the ability to access information about the user's system.
API
Example
Permissions
operatingSystem returns a promise with a string that describes which operating system the Loop is running on.
import { system } from '@oliveai/ldk';
system.operatingSystem().then((os) => {
console.log(os);
});
/*
* This will print out one of:
* windows
* darwin (This will be returned for macOS)
* linux
*/
getEnvironment returns a promise with an object that contains the osVersion, oliveHelpsVersion, and the loopVersion.
import { system } from '@oliveai/ldk';
(async () => {
const environment = await system.getEnvironment()
console.log(environment.osVersion)
console.log(environment.oliveHelpsVersion)
console.log(environment.loopVersion)
});
In some cases you may need to do something specific to the operating system, whether it's loading a specific configuration file or retrieving data from an API. Here's a quick example on how to do both using the System aptitude, Filesystem aptitude, and Network aptitude.
import { filesystem, network, system } from '@oliveai/ldk';
const CONFIG_FILE = {
windows: './windows.json',
darwin: './darwin.json',
};
const SUPPORTED_OS = Object.keys(CONFIG_FILE);
function validateOS(os) {
if (!SUPPORTED_OS.includes(os)) {
throw new Error(`This example does not support ${os}.`);
}
return os;
}
function getConfig(os) {
return CONFIG_FILE[os];
}
function buildNetworkRequest(config) {
return {
url: config['url'],
method: 'GET',
};
}
system.operatingSystem()
.then(validateOS)
.then(getConfig)
.then(filesystem.readFile)
.then(network.decode)
.then(JSON.parse)
.then(buildNetworkRequest)
.then(network.httpRequest)
.then( /* Do something with the request */ )
.catch((e) => console.log(e));
To use the System Aptitude, simply set the following permissions in your
package.json under the ldk object.
...
"ldk": {
"permissions": {
"system": {},
...
}
},
