Relative Links with IBM Cloud API Gateway

I work quite a bit with serverless tech, particularly on IBM Cloud since I work there. At the moment I'm building a microservice using web actions. When a user creates data with a POST request, I want to redirect them to the URL of the new thing they created - but for that I need to know the URL that it was accessed with. This is a relatively new feature on API Gateway so here's a quick howto for grabbing that URL in both JavaScript and PHP. Continue reading

React to Database Changes with OpenWhisk Actions

One of the best features of CouchDB is its change feed which allows us to get a feed of the changes happening on our database. It's also possible to have a serverless function (examples are for IBM Cloud Functions but should also work for Apache OpenWhisk) that fires in response to activity on that change feed. I have a database of events that I want to react to when they happen, but the change feed doesn't include the actual document that was added - but you can add one of the built-in functions to a sequence to make that happen. This post will show how to achieve this by wiring up a built-in action to fetch the document with another action of our own that then handles the data. Continue reading

Handle Webhooks with Serverless PHP

Did you know you can serverless with PHP? OK, so serverless is clearly not a verb, but since I love serverless tech and have also loved PHP for longer than I'm going to admit (the dates of the earliest posts on this blog might serve as a clue), using these technologies together is definitely my idea of a good time.

I included an example of a serverless endpoint to receive incoming webhooks in my talk at PHPUK last week and I got a few questions about it so I thought I'd share that example in written form. Continue reading
