Anyone have suggestions for a good Rust template engine?
I'm running a server-side-rendered web server using Actix Web. Any suggestions for a client? All I really need is something fast and that I can use without breaking my neck (don't need any fancy VDOM, trying to ship minimal JS).
Try askama, it also has a crate to integrate actix-web called askama_actix. It's jinja like template engine
Can't beat askama. There are other Jinja-like templates but askama has best-in-class performance and compile time safety.
When you say "best in class performance", do you have particular benchmarks in mind?
I only found this one: https://github.com/rosetta-rs/template-benchmarks-rs
Askama was neither fastest not slowest. Purely based on benchmarks sailfish seems to be interesting as well
Is there any way to track values without a struct? Or in my specific case, I’m using a struct, but most of the values are in an Option<String>.
I've been using tide-jsx, but I'm also using tide (not actix). Everything renders to a String, so it would technically be compatible with any web framework.
I would love to see what other people suggest for Actix since I wanted to use that instead of Tide, but I also didn't know where to find a crate like tide-jsx. https://crates.io/crates/tide-jsx
Thanks, this is a lot like what I was looking for. Will try it out.
You may need to fork the repo and mirror my pull requests into your fork. The maintainer of the repo hasn't responded to my pull requests yet and one of them fixes a common bug.
In your Cargo.toml file, you can reference your own fork as a dependency. https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#specifying-dependencies-from-git-repositories
Check out these benchmarks. https://github.com/rosetta-rs/template-benchmarks-rs
Particularly the implementation of the benchmark for each crate.
I came here to ask a similar question so I may as well throw it into the comments of this one just to make sure I don't end up cluttering the community.
In my case though, I have a few extra requirements the existing answers can't handle:
I think all of these can be recompiled at runtime.
Askama seems to be a popular and mature option here. Yew is also pretty popular here, uses a VDOM and provides a powerful front end (great for SPAs) I’m most likely going to go with tide-jsx, it’s like HTML but it supports Rust expressions thru a macro, which is exactly what I need. Liquid is also pretty secure, so that’s an option.
Askama and Yew are pretty mature, so they probably have reasonable security. I would check their docs, however.
Perhaps "recompilation" wasn't the right word to use there.
My goal is to let people customize the templates that will end up building the pages, either from the app itself or through a companion panel app of sorts. This excludes anything that compiles down to native code, so it must be something interpreted at runtime.
My go to for static content is astro.js. It gives a really nice developer experience that is really just writing HTML but with the quality of life of reusable "components", all with 0 JS by default.
Ultimately, I ended up using Astro, Rust was giving me too much pain for no tangible gain.
i have used the handlebars crate, and it is great for really simple templating. it is extensible with 'helpers', but imo a bit annoying for more complex use.
