$ npm install --save classy-lambda-common
Minimally, you must have an environment.json and creds.example.json file in the root of your project. The JSON content provides a configuration based on which stage you are deployed to:
environment.json
{
"dev": {
"aws": {
"region": "us-west-2"
}
},
"staging": {
"aws": {
"region": "us-west-2"
}
},
"production": {
"aws": {
"region": "us-east-1"
}
}
}
creds.example.json
{
"SECRET": "SHHHH"
}
See prerequisites
Common.get(key): works for both static environment key/value pairs (i.e. environment.json), and also CredStash secrets. For static environment key/value pairs, you can specify nested keys in hierarchy via dot notation, i.e. Common.get('this.is.valid') returns "value" for:
{
"dev": {
"this": {
"is": {
"valid": "value"
}
}
}
}
For CredStash, keys are generally all uppercase with snake case between words, i.e. SOME_SECRET.
Common.get('Logger'): Logging facility which requires 'log' configuration. See example below.
Common.get('PayClient'): Client which can be used for requests to Classy Pay. Requires 'pay' configuration.
Common.get('ApiClient'): Client which can be used for requests to Classy API. Requires 'api' configuration.
Common.get('Replacer'): Obfuscator for use with JSON.stringify replacer. Requires 'security' configuration.
Bootstrap: Common.load(callback)
const Common = require('classy-lambda-common');
Common.load(function(error) {
if (error) {
console.error(error);
} else {
let logger = Common.get('Logger').create('my-logger');
logger.info('Hello World');
}
});
Get static config: Common.get(key)
let value = Common.get('some.key');
console.log(value);
Get CredStash secret: Common.get(key)
let value = Common.get('SOME_SECRET');
console.log(value);
Get Logger: See Bootstrap above
Get PayClient: Common.get(key)
let PayClient = Common.get('PayClient');
// PayClient.request(appId, method, resource, postBody, callback)
PayClient.request(0, 'GET', '/transaction/1', null, function(error, result) {
if (error) {
callback(error);
} else {
console.log(result);
}
});
Get ApiClient: Common.get(key)
let ApiClient = Common.get('ApiClient');
// See classy-node for details
ApiClient.app().then(() => {
ApiClient.organizations.retrieve(1, {
token: 'app'
}).then((result) => {
console.log(result);
});
});
Get Replacer: Common.get(key)
let Replacer = Common.get('Replacer').replacer;
console.log(JSON.stringify({
cvv: '123'
}, replacer, 2));
