The first one we added was the "copy" method. Here is a simple get in action: Add Business Object BehaviorsĬRUD methods are great but the cool stuff usually happens in a custom behavior added to a business object. At this point, we have only implemented the "all" method on the connector so only the get and get by id work. ![]() Restart your app manager and open the API Explorer. Copy the contents of this file and paste it as the value of the "googleApiCredentialsJson" environment variable on your App Manager. Once you have set up your service account, you will have a JSON file containing the public/private key pair downloaded on your machine. This connector uses a service account to access the Google APIs. When we generate the test app, we now have a full set of Create, Read, Update and Delete REST APIs: Configure the Data Source and Try It Out These form the subset of the Google Drive File resource that we are interested in for now. For this post, we will focus on the Google Drive File business object. Now that we have a connector and a data source, we can create the business objects for the library. It sets up the debug module, pulls in the googleapis package, declares the class and constructor:Ĭonst debugClass = require('debug')('GoogleDriveLibrary:GoogleDriveConnector') ĭebugClass.log = (console) Ĭonst )Ĭreate a Google Drive File Business Object I went to /files/loopback/src/datasources and created a file called "". Ideally, a connector should be a separate npm package, but in this case, I created it directly in the project. Apex Designer allows you to edit generated code as well as add new code alongside the generated code. Create a ConnectorĬreating a Loopback connector is a "pure code" part of the low-code experience. I added the Google Drive Library as a dependency and checked the box to have the test app regenerate any time the library is generated. I created an application called Test Google Drive Library using the Angular 10 and Loopback 4 Template Project. I skipped the Angular-related libraries for now because this library does not have any UI components. I also added the Loopback 4 Base Library. I created an empty Apex Designer project called Google Drive Library and set the project logo and description. I will walk through the steps I took to build a Google Drive Library to support an onboarding process that includes generating, collaborating and signing contracts. It can anyone interested in building Loopback connectors. This post is for anyone that wants to understand what is under the covers of an Apex Designer integration library. The low-code environment of Apex Designer makes it easy to use connectors like these by simply adding one of the pre-built libraries and configuring the connection credentials. But a datasource can also be a SaaS application like Box, AWS Simple Email Service, and the Camunda Process engine. A Loopback application can be a "mash up" of several data sources using different connectors including lots of sql and no-sql databases. ![]() For the server-side app, it generates a Loopback node.js application. Apex Designer is a low-code design tool that generates an app that runs on an open source stack.
