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 wrote previously about how to implement a dynamic redirect mechanism for Azure Static Web Apps using Azure Functions. I implemented this using JSDoc JavaScript. I've since migrated this to TypeScript and I thought it would be interesting to share the process.

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.

I've written previously about using Structured Data with React. This post goes a little further and talks about how to use Structured Data with Docusaurus and MDX. More specifically it looks at how to create a component that both renders FAQs into a page, and the same information as Structured Data.

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.

Azure Static Web Apps staging environments allow you to test changes before they go live. This post shows how to use Playwright against staging environments with GitHub Actions. It's a follow up to my previous post on using Lighthouse with Azure Static Web Apps staging environments.

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.

Node.js 18 doesn't allow legacy TLS renegotion by default. But some APIs still need it. This post shows how to support them with Axios.

Not everyone values pull requests. I really do, and this post explains why.

By default, Docusaurus blogs don't add breadcrumb Structured Data to their blog posts. It's not hard to make it happen though; this post shows how to add it using the JSON-LD format.

You can use Bicep and GitHub Actions to build and deploy to a static website on Azure Static Web Apps. This post demonstrates how.

A new API landed in Docusaurus 2.3.0 - it's called createFeedItems. It's a great API that allows you to tweak the Atom / RSS / JSON feeds for your blog. This post shows how to use it with the git commit date.

Image optimisation can be automated with the TinyPNG API. This post demonstrates how to do that.

By using fetchpriority on your Largest Contentful Paint you can improve your Core Web Vitals. This post implements that with Docusaurus.

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.

Support for Node.js 16 for Azure Pipelines custom pipelines task extensions has arrived. From a TypeScript perspective, this post documents how to migrate from a Node.js 10 custom task to one that runs on Node 16 using azure-pipelines-task-lib.

Application Insights are a great way to monitor Azure Static Web Apps and Azure Functions. But how do you deploy that using Bicep? Let's find out!

Cloudinary offers an image CDN which can improve performance of your site. This post details how to get Docusaurus to use Cloudinary to serve optimised images.

Azure Static Web Apps can perform URL redirects using the routes section in the staticwebapp.config.json. However it is limited. This post will demonstrate dynamic URL redirects with Azure Functions.
