I make use of Azure Static Web Apps a lot. I recently upgraded to Node.js 18 and found that the Static Web Apps CLI no longer worked when trying to run locally; the API would not connect when running swa start:

[swa] ❌ Could not connect to "http://localhost:7071/". Is the server up and running?

This post shares a workaround.

I really like type imports that are unambiguous. For this reason, I've made use of the "importsNotUsedAsValues": "error" option in tsconfig.json for a while now. This option has been deprecated in TypeScript 5.0.0, and will be removed in TypeScript 5.5.0. This post will look at what you can do instead.

I've written previously about sending Teams notifications using a webhook, and it's a technique I've used a lot. But I've always wanted to be able to send a direct message to a user, and that's not possible with the webhook approach. I work with a marvellous fellow named Chris Tacey-Green, and he's figured out a way to do this using Power Automate and the Teams Notification API. I'm going to describe how he did it here, with a little help from him.

It's probably worth saying, both Chris and I work for Investec, and we're going to share some of the things we've learned about using Teams and Power Automate in the hope that it's useful to others. But we're not speaking on behalf of Investec, and we're not suggesting that this is the best way to do things. This is likely in the "do things that do not scale" category. Significantly though, it works!

You will see some screenshots of our internal Teams environment, but we've tried to keep them to a minimum, and we're not going to share any sensitive information.

When sending a single item array to a Bicep template you may get an error like this:

ERROR: InvalidTemplate - Deployment template validation failed: 'Template parameter 'allowedIPAddresses' was provided an invalid value. Expected a value of type 'Array', but received a value of type 'String'.

This is down to the fact that Bash arrays when used with the Azure CLI can be a little surprising. If we initialise a single item array then it's not an array. It's a string. This is a bit of a pain when you're trying to pass a single item array to a Bicep template. It's possible to work around this with JSON and Bicep user defined types. Let's see how.

I've wanted to take a look at some of the alternative JavaScript runtimes for a while. The thing that has held me back is npm compatibility. I want to be able to run my code in a runtime that isn't Node.js and still be able to use npm packages. I've been using ts-node for a long time now; it's what I reach for when I'm building any kind of console app. In this post I want to port a console app from ts-node to Bun and see how easy it is.

In October 2022 traffic to my blog dropped like a stone. What happened? Somehow I ruined my SEO. Don't be me. I'll tell you what I got up to and hopefully you can avoid doing the same.
