    An inline template style for dynamic config files


    Sometimes you just need some simple one line configuration templates. A few scattered across the page with no need for logic or looping, just some quick and dirty text replacement. Enter lineup! It's nothing fancy, simply developed for those times when you need to provide a few text replacements from a JSON source and you don't want to unpack the object or have to write a function for a string.replace call to map an object to the string.


    • Bower: install with bower install lineup and include in a script tag on your page. The library will be accesible globally via the lineup(template, data) function.
    • Browser: download lineup.js from github, place in your project directory, and include in a script tag on your page. The library will be accesible globally via the lineup(template, data) function.
    • NPM: install with npm install lineup-template. The library can be used with var lineup = require("lineup-template");.

    lineup(template, data)

    lineup templates only have one type of markup: the data tag. Surround any alphanumeric identifier with % symbols to turn it into a data tag. For example, This piece of text contains one %datatag% has a tag called datatag. When the template is executed, lineup will retrieve the property called datatag from the provided data object and replace it inline. Using the previous example, executing lineup(template, {datatag: "kitten"}); would return This piece of text contains one kitten.

    There can be no whitespace within a data tag, as this is the method by which lineup distinguishes between normal % symbols and data tags.

    Slightly More Advanced

    Data tags can identify properties in a data object at an arbitrary depth by seperating identifiers with a period. With the template I really like %animal.colour%, the function call lineup(template, {animal: {colour: "purple", "name: "jaguar"}}); would return I really like purple jaguars.


    npm i lineup-template
