An AWS Lambda driven static site generator written in Kotlin. Source markdown files will be converted to HTML
using the Flexmark-java library, and further processed using handlebars.
java, in AWS Lambda functions triggered by PUT events on a source S3
bucket.
The resultant HTML will be written to a separate S3 bucket, configured as a static website.
I haven't quite worked out how to handle site navigation / internal links, but my current thinking is this will be fully browser-rendered in javascript, based on a generated site map file (or database?).
Longer term, I'd like to build several interfaces to creating and editing the markdown files, including a website and an Android phone app.
I will be using AWS Cloudformation and the CDK to build this project. Although this ties me to AWS as a Cloud provider, I'm largely OK with that limitation.
I am writing primarily in Kotlin as it is my language of choice. I know that JVM-based Lambda functions are not the best performing, especially with start-up times, but I am not sure that performance is a priority for me. Perhaps with GraalVM is can be improved. I considered using a nodeJS/Javascript markdown-to-html Lambda function, but I am not a Javascript developer and have very little experience of the nodeJS ecosystem.
The root project will use AWS CDK to build the AWS Cloudformation templates, to set up S3 buckets, Lambda functions, API gateway, and so on. I have a little experience in using CDK for this.
Sub-modules in the project will provide the Lambda functions for HTML generation, templating, and other actions.
- I have also included a Web front-end in this project, but I think that is a mistake. Front-ends should be in a separate project and a separate repository. While it might be nice to share data classes between front and back ends, I could probably do that by building a separate .jar file from my
SharedModelsmodule. - The long-term goal is to have Web, Android and Desktop front-ends, but I haven't decided on the approach for that. It makes sense to use Jetpack Compose for the desktop and android interfaces, but I don't think that's a good fit for web. For now, I am writing a web front end using sveltekit. But I really dislike writing Javascript, and Typescript doesn't improve my mood either.
This could be considered a successor to my bascule static site generator, a command-line driven application which got weighed down by poor program design and my own lack of experience. I have been keen to rebuild bascule as web-first application for several years, frustrated by my inability to make website updates away from my PC.
