Mostachito
Disclaimer: a very simplistic templating engine.
Usage
Syntax
- Template references:
- Simple
{{ myVar }} - Nested data
{{ my.var.is.nested }} - Iterable
{{posts as post The post with name: {{ post.title }}, was created on {{ post.date }}! posts}}
- Simple
- Passing the template and data to the template engine
import Mostachito from 'mostachio'; const te = new Mostachito(); const myText = 'Hello {{ my.data.is.deep }}, how are you ?'; const data = { my : { data : { is : { deep : 'Liz' } } } }; const replacedText = te.replace(myText, data); console.log(replacedText);// "Hello Liz, how are you ?"
Example
Create a view like so:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>{{ siteTitle }}</title>
<meta name="description" content="Simplest Blog in Nodejs">
<meta name="author" content="George Mostachito">
<link rel="stylesheet" href="css/styles.css?v=1.0">
<link rel="stylesheet" href="css/highlight-js-github.css">
</head>
<body>
<h1>{{ siteTitle }}</h1>
<h2>{{ missingRef }}, {{ hey.missingRef }}, {{ hey.hoy.missingRef }}</h2>
<ul>
{{posts as post
<li><a href="/{{ post.attributes.slug }}">{{ post.attributes.title }}</a><div class="post-preview">{{ post.body }}</div></li>
posts}}
</ul>
</body>
</html>Import the contents and replace:
import Mostachito from 'mostachio';
function loadViewTemplate(viewData) {
return new Promise(function(resolve, reject) {
fs.readFile('path/to/my/template.html', 'utf-8', function(err, viewTemplate) {
if (err) return reject(err);
resolve({viewTemplate, viewData});
});
});
}
function hydrateView({viewTemplate, viewData}) {
const configViewData = this.config.viewData || {};
viewData = {...configViewData, ...viewData};
const mostachito = new Mostachito(this.config.missingRefValueReplacement);
const hydratedView = mostachito.hydrate(viewTemplate, viewData);
this.response.code = 200;
this.response.headers = {'content-type': 'text/html; charset=utf-8'};
this.response.body = hydratedView;
return this.response;
}
loadViewTemplate({my: 'viewData'}, that: 'I want to pass', arr: ['a', 'b', 'c', 'd'])
.then(hydrateView)
.catch(err => console.log(err));
