str-literals

Dynamic string template with simple expressions support.

The idea to use format similar to JS template literals, but be able to get it dynamically.

You can use all global functions and objects unless you don't using "{" and/or "}" inside "${}".

Be carreful when using this module, expression evaluation using eval function.

npm install str-literals

Examples

const template = require('str-literals')
// const who = 'World'
// console.log( `Hello, ${who}!`)
console.log( template('Hello, ${who}!', {who: 'World'}))

Output:

Hello, World!

No variables:

const template = require('str-literals')
console.log( template('Total: ${1+1}') )

Output:

Total: 2

JS Array expression

const template = require('str-literals')
console.log( template('Note: ${arr.join("")}', {arr: ['Hello, ', 'World', '!']}))

Output:

Note: Hello, World!
