Tag Templates (@peter.naydenov/tag-templates)
Template engine build on top of javascript native technologies: template literals and tag functions.
Installation
Install the package:
npm i @peter.naydenov/tag-templates
Request the module from the script:
const tagTemplates = require ( '@peter.naydenov/tag-templates' );
Methods
Engine have just two methods: addTemplate and render. Both are receiving parameters as text strings. Look at "How to use it" section.
{
addTemplate : 'Write a template'
render : 'Convert data+template into a rendered block'
}
Configuration object
All configuration fields are optional.
{
TG_PRX : '{{' // Change default placeholder's opening tag
, TG_SFX : '}}' // Change default placeholder's opening tag
, DV : ':' // Chnage default props divider
, debug : false // Set on 'true' to receive more warnings and error messages
}
How to use it
const tagTemplates = require ( '@peter.naydenov/tag-templates' );
// Create a render engine instance:
const engine = tagTemplates ()
// Set a template "hello".
engine.addTemplate`
hello
<title>Hello {{name}}</title>
<p>{{msg}}</p>`
// Other technique when template is defined as external variable.
let nextTemplate = `
show
<p>User {{name}} is {{age}} years old.</p>`
engine.addTemplate`${nextTemplate}`
// After version 1.2.0 "addTemplate" could work like:
let
title = '<h1>{{title}}</h1>'
, txt = '<p>{{text}}</p>'
;
engine.addTemplate`
news
${title}
${txt}`
engine.render`
news
title : my own news channel
txt : Just started to write `
/**
* result:
* <title>my own news channel</title>
* <p>Just started to write</p>
*
*/
// Render template 'hello' with data:
let block = engine.render`
hello
name : Peter
msg : Welcome to this page`
/**
* result:
* <title>Hello Peter</title>
* <p>Welcome to this page</p>
*/
// Other way to provide the data for template "hello"
let
myMsg = 'Other message'
, myName = 'Kris'
;
block = engine.render`
hello
name : ${myName}
msg : ${myMsg}`
/**
* result:
* <title>Hello Kris</title>
* <p>Other message</p>
*/
If templates for your project are already created and they are not in mustache style, then modify the template engine by providing a configuration object:
let
config = {
TG_PRX : '<<' // Change of opening tag
, TG_SFX : '>>>' // Change of closing tag
, DV : '-->' // Data devider is also customizable
}
, vm = tagTemplates ( config )
;
// Provide template with your custom style
vm.addTemplate`
test
Your name is <<name>>>`
// Render
let block = vm.render`
test
name --> Peter`
// Result --> 'Your name is Peter'
