sfdx-cli-helper v1.0.4
SFDX CLI Helper
The SFDX CLI Helper package provides SFDX plugin developers with utilities to help re-use commands across multiple plugins. The first of these is the ConfigHelper class for adding config:set and config:show commands to your plugins.
Installation
$ npm install --save sfdx-cli-helper
Implementation
configHelper.js
Example 1. Adding a config:set command
You can use this module to uniformly add a yournamespace:config:set command to all of your plugins. The sample below includes validation of configuration keys.
Note: Command help code omitted for simplicity.
import { SfdxCommand } from '@salesforce/command';
import { AnyJson } from '@salesforce/ts-types';
import { ConfigHelper } from 'sfdx-cli-helper'; // Import the ConfigHelper class
export default class Set extends SfdxCommand {
// Enable key-value pair as an argument
public static varargs = {
required: true
};
public async run(): Promise<AnyJson> {
/**
* Instantiate helper class, passing valid config keys to the constructor.
* Attempts to set a key-value pair not in this list will display an error.
*/
const helper = new ConfigHelper({validKeys: [
'configKey1',
'configKey2',
'etc',
]});
// Pass the key-value pair argument to set the config value
try {
helper.setValue(this.varargs);
console.log('Value(s) set successfully');
} catch (exc) {
console.error(exc.message);
}
return;
}
}
Once you've placed the above code in src/commands/yournamespace/config/set.ts, you can set one or more config values as below.
# one value
$ sfdx yournamespace:config:set configKey1=value
# multiple values separated by pipe (|)
$ sfdx yournamespace:config:set configKey1=value1|configKey2=value2
Example 2. Adding a yournamespace:config:show command
You can use this module to uniformly add a yournamespace:config:show command to all of your plugins.
Note: Command help code omitted for simplicity.
import { SfdxCommand } from '@salesforce/command';
import { AnyJson } from '@salesforce/ts-types';
import { ConfigHelper } from 'sfdx-cli-helper';
export default class Show extends SfdxCommand {
public async run(): Promise<AnyJson> {
const settings = ConfigHelper.getSettings();
console.log(settings);
return;
}
}
Once you've placed the above code in src/commands/yournamespace/config/show.ts, you can view your configuration settings with the following command.
$ sfdx yournamespace:config:show
Configuration File Setup
On the first run of your config:set command, the following two files will be created under resources. The files below store the location of your settings and the settings themselves respectively.
.
+-- resources
| +-- config-settings.json # contains location of config file (plugin-config.json)
| +-- plugin-config.json # contains config keys and values in json format
Defaulting Command Arguments to Config Values
For any command where you want flags to automatically default to configured values, implement code similar to the following two examples:
Load the settings file configured in the helper
import { flags, SfdxCommand } from '@salesforce/command'; import { Messages } from '@salesforce/core'; import { AnyJson } from '@salesforce/ts-types'; // Load configuration settings const settings = ConfigHelper.getSettings();
Set default values from the keys in your config file as in the following example:
protected static flagsConfig = { apikey: flags.string({ char: 'k', default: settings.apiKey, description: 'the api key', required: true }), // configurable // other flags ... };
