Server-side rendering (node)

          Also, does it support server-side rendering?

Hi @Zonalds, Unfortunately, we don't have out-of-box support for server-side rendering. We had a test branch earlier based on an old version (0.3.3): https://github.com/vizzuhq/vizzu-lib/tree/nodejs, what we wanted to use for our test environment, but it did not make it to the main branch. We ended up using selenium-chromedriver to render the tests on server-side.

If there is a need, we can revisit this topic. I am curious about what would be your use case for server-side rendering.

nodejs branch:

• build cvizzu (project/cmake/weblib/emcc.txt) with wlags: EXPORT_ES6=0 ENVIRONMENT='node'
• a script replace import/exports during the build
• in not generated js files in the api if/else statements for env specific parts (vizzu.js, render.js htmlelement, performance, document)

rollup version:

• in rollup cfg cjs
• build cvizzu (project/cmake/weblib/emcc.txt) with wlags: EXPORT_ES6=1 ENVIRONMENT='node'
• import/exports will be good, not needed to replace during build
• in not generated js files in the api if/else statements for env specific parts (vizzu.js, render.js htmlelement, performance, document)
• it could place the wasm with async load in base64

I was a commit that uses an HTML canvas element on text width measure. This should be hidden behind the canvas interface. See here and here. Probably it can be replaced to OffscreenCanvas.
