Svelte / Sapper deploy
I started to play with Svelte / Sapper as an alternative to Angular.
The development of a simple application is quick and intuitive, I had issues to deploy a small application easily in the cloud.
The solution I found is to create a Docker image of the application and deploy it using Jelastic.
Being the content quite static I exported the result of the original REST answers of the Java backend in JSON files.
The website is visible here: java-version.com
FROM node:14-alpine WORKDIR /usr/src/app # the entire project is copied COPY / ./ RUN npm install RUN npm run build CMD ["node", "__sapper__/build"] EXPOSE 3000 ENV HOST=0.0.0.0
I deployed the image behind a NGINX Load Balancer.
The main issue for me was the configuration of different environments: development and ‘production’. In Angular and Java every environment has his own configuration file out of the box.
I didn’t find this in Sapper. The solution was to use external plugins. Even changing the port of the server required searching a solution on GitHub (prefix with PORT 80 the starting instruction was the easiest).
Working with different environments and services (backend etc.) it’s annoying to don’t have a pre-defined solution.
I like Svelte a lot. The main project comes with some companion solution for SSR and static website generation that fill some missing features of Angular. The compilation central idea is a true alternative to React/Vue/Angular. Unfortunately Svelte doesn’t seem to receive a lot of interest in the enterprises.
