After working on html templating for ~10 years, I think the best template library is no template library.
NoTemplate.js provides only two functions, tag() and raw(). Use nested tag() calls to build a DOM tree in pure JS in a concise and safe manner without any special syntax, compiler or preprocessor; raw() can be used to mark "safe" raw HTML content that won't be escaped.
The first parameter of tag() is the element name. Each HTML5 element also has a helper function registered on the tag function, so instead of using tag("p", ...), one can also use tag.p(...).
Additional parameters build the content:
- Strings are safely added as text nodes. No need to escape anything.
- DOM Nodes (in particular elements) are added as child nodes.
- Properties of nested plain objects are treated as
- Attributes where the value is a string
- Boolean attributes where the value is a boolean (empty string for true, absence otherwise)
- Event handlers where the value is a function
- For "style", the value can be an object, which is translated to style properties
- For "class", the value can be an array
- Arrays are automatically flattened to simplify building from fragments.
- Null values are ignored to simplify handling conditional children
For components, create functions that return elements.
As much as vanilla.js: I am using this myself for quotations.ch to simplify "old-school" HTML construction from JavaScript, replacing direct use of the DOM API. For larger projects, it might make more sense to use something like vue.js to decouple rendering and state management. I hope this project might help people to "get going" with small projects without pulling in half the world as dependencies.
Let me know if I should add anything here.
document.body.appendChild(
tag.p(
"Hello ",
tag.a({
href: "#",
click: event => alert("Hello")},
"World")));- Source Code (< 150 LOC; the view code starts around line 56)
