Turbx
A Fast and Easy To Use View Engine, Compiled In Go.
Whats New
- Compiler will auto compress to gzip or brotli if the browser supports it
Installation
sudo apt-get install libpcre3-dev
npm install turbx
Setup
const express = require('express');
const {join} = require('path');
const turbx = require('turbx');
const app = express();
app.engine('xhtml', turbx({
/* global options */
template: 'layout',
opts: {default: 'some default options for res.render'},
before: function(opts){
// do stuff before res.render
},
after: function(opts, html /* html string containing the compiled output */){
// do stuff after res.render
},
}));
app.set('views', join(__dirname, 'views'));
app.set('view engine', 'md');
app.use(function(req, res, next){
res.render('index', {
title: 'example',
content: '<h2>Hello, World!</h2>',
// const vars can be used to precompile a var, and not need to compile it again
// a const var is defined by starting with a '$' in the key name
$GoogleAuthToken: 'This Value Will Never Change',
});
});
// pre compiling constant vars
app.use(async function(req, res, next){
let preCompiled = await res.inCache('index');
if(!preCompiled){
const SomethingConsistant = await someLongProcess();
await res.preRender('index', {
$myConstVar: SomethingConsistant,
});
}
res.render('index', {
title: 'example',
content: '<h2>Hello, World!</h2>',
});
});
// pre compiling and overriding the cache
app.use('/fix-cache', async function(req, res, next){
turbx.preCompile('index', {
$MyConstOpts: 'new constant option',
});
res.render('index', {
title: 'example',
content: '<h2>Hello, World!</h2>',
});
});
Usage
<!-- this is a comment -->
/* this is also a comment */
// this is an inline comment
<!-- output a variable with escaped HTML -->
{{title}}
<!-- output a variable and allow HTML -->
{{{content}}}
<!-- output a variable with a fallback -->
{{title|name|'Default Title'}}
<!-- output a variable as an attribute (this method will remove the attribute if the value is undefined) -->
<a {{href="url"}}>Link</a>
<!-- this is a shortcut if the attribute name matches the variable name -->
<a {{="href"}}>Link</a>
<!-- you can safely insert object keys (if an object is undefined, this will return blank, and will Not crash) -->
{{obj.key}}
<!-- use dot notation for array indexes -->
{{arr.0}}
<!-- use the value of the "key" var as the key of "obj" -->
{{obj[key]}}
{{obj[myVar]}}
<!-- using vars as if they were constant -->
{{$normalVal|'make this constant anyway, even if not sent as a constant'}}
<!-- functions start with an _ -->
<_if var1 & var2="'b'" | var2="'c'" | !var3 | (group & group1.test1)>
do stuff...
<_else !var1 & var2="var3" | (var3=">=3" & var3="!0")/>
do other stuff...
<_else/>
do final stuff...
</_if>
<_each myObj as="value" of="key">
{{key}}: {{value}}
</_each>
<!-- A component is imported by using a capital first letter -->
<!-- The file should also be named with a capital first letter -->
<!-- args can be passed into a component -->
<MyComponent arg1="value 1" arg2="value 2">
Some body to add to the component
</MyComponent>
<!-- component without a body -->
<MyComponent arg1="value"/>
<!-- file: MyComponent.xhtml -->

turbx.renderPages(app, {opts});
// also recognizes folders with an index.xhtml file
// ignores the components folder and tries to ignore root files named after error codes (or in an "error" folder)
