It lacks important features such as HTML 16 | escaping!* 17 | 18 | 19 | ## Usage 20 | 21 | All the examples can be found in [rscx/examples/](https://github.com/Pitasi/rscx/tree/main/rscx/examples). 22 | 23 | ```rs 24 | use rscx::{component, html, props, CollectFragment}; 25 | 26 | #[tokio::main] 27 | async fn main() -> Result<(), Box> { 28 | let app = app().await; 29 | println!("{}", app); 30 | Ok(()) 31 | } 32 | 33 | // simple function returning a String 34 | // it will call the Items() function 35 | async fn app() -> String { 36 | let s = "ul { color: red; }"; 37 | html! { 38 | 39 | 40 | 41 | 42 | 43 | 44 | // call a component with no props 45 |
46 | 47 | // call a component with props and children 48 |
49 | 50 |
51 | 52 | 53 | } 54 | } 55 | 56 | #[component] 57 | /// mark functions with #[component] to use them as components inside html! macro 58 | fn Section( 59 | // you can use `builder` attributes to specify a default value (makes this prop optional) 60 | #[builder(default = "Default title".into(), setter(into))] title: String, 61 | #[builder(default)] children: String, 62 | ) -> String { 63 | html! { 64 |
65 |

{ title }

66 | { children } 67 |
68 | } 69 | } 70 | 71 | #[component] 72 | async fn Items() -> String { 73 | let data = load_data_async().await; 74 | html! { 75 | 83 | } 84 | } 85 | 86 | /// async functions can be easily used in the body of a component, as every component is an async 87 | /// function 88 | async fn load_data_async() -> Vec { 89 | vec!["a".to_string(), "b".to_string(), "c".to_string()] 90 | } 91 | ``` 92 | 93 | 94 | ## Benchmarks 95 | 96 | RSCx is fast. 97 | 98 | *Disclaimer*: RSCx is for servers, as the name suggests. Therefore the following 99 | comparisons with Leptos are unfair. This library contains only a fraction of 100 | Leptos' features. 101 | 102 | *Disclaimer 2*: The benchmarks are pretty basics and should not influence your 103 | decision on whether to use or not this library. Focus on the DX. They are 104 | included as I kept running them to make sure I didn't fall too much behind 105 | alternatives. 106 | 107 | The time in the middle of the three is the average. 108 | 109 | ### Run the benchmarks locally 110 | 111 | ``` 112 | cd bench 113 | # cargo install criterion 114 | cargo criterion 115 | ``` 116 | 117 | 118 | ### Benchmark 1: single element, lots of HTML attributes 119 | 120 | ``` 121 | many_attrs/maud_many_attrs 122 | time: [205.89 ns 208.35 ns 211.53 ns] 123 | many_attrs/horrorshow_many_attrs 124 | time: [37.221 µs 37.304 µs 37.401 µs] 125 | many_attrs/html_node_many_attrs 126 | time: [67.726 µs 67.830 µs 67.939 µs] 127 | many_attrs/leptos_many_attrs 128 | time: [923.31 ns 928.46 ns 935.04 ns] 129 | many_attrs/rscx_many_attrs 130 | time: [207.96 ns 212.82 ns 219.28 ns] 131 | ``` 132 | 133 | RSCx and Maud pretty much are the same as their macros output is effectively a 134 | static string with the result. 135 | 136 | 137 | ### Benchmark 2: little element with props and child 138 | 139 | ``` 140 | small_fragment/maud_small_fragment 141 | time: [107.60 ns 107.71 ns 107.81 ns] 142 | small_fragment/horrorshow_small_fragment 143 | time: [405.98 ns 406.08 ns 406.21 ns] 144 | small_fragment/leptos_small_fragment 145 | time: [1.7641 µs 1.7652 µs 1.7662 µs] 146 | small_fragment/rscx_small_fragment 147 | time: [101.79 ns 101.87 ns 101.97 ns] 148 | ``` 149 | 150 | RSCx offers a better DX than Maud, as the syntax is nicer and values such as i32 151 | can be passed as props/attributes, while in Maud every attribute must be a 152 | static string. 153 | 154 | 155 | ### Benchmark 3: dynamic attributes (read for variable) 156 | 157 | ``` 158 | many_dyn_attrs/horrorshow_many_dyn_attrs 159 | time: [50.445 µs 50.702 µs 50.977 µs] 160 | many_dyn_attrs/leptos_many_dyn_attrs 161 | time: [100.13 µs 100.52 µs 101.00 µs] 162 | many_dyn_attrs/rscx_many_dyn_attrs 163 | time: [33.953 µs 33.990 µs 34.037 µs] 164 | ``` 165 | 166 | 167 | ### Benchmark 4: async component rendering a list of 100 items 168 | 169 | ``` 170 | async_list/maud_async_list 171 | time: [2.3114 µs 2.3241 µs 2.3377 µs] 172 | async_list/leptos_async_list 173 | time: [55.149 µs 55.228 µs 55.315 µs] 174 | async_list/rscx_async_list 175 | time: [5.4809 µs 5.4987 µs 5.5151 µs] 176 | ``` 177 | 178 | I'll reiterate the disclaimer: Leptos is not specifically made for SSR. Going 179 | through its reactivity system (using async resources) adds overhead. 180 | 181 | -------------------------------------------------------------------------------- /benches/Cargo.toml:
