## What it is
Consolidate.js is a Node.js library that provides a unified API over dozens of JavaScript template engines (EJS, Handlebars, Pug, Mustache, etc.). It is commonly used as the view-engine integration layer for Express 3.x/4.x applications.

## Use cases
- render templates in express with multiple template engines
- swap template engines without changing app code
- unified api for ejs handlebars pug mustache
- use handlebars as express view engine
- normalize template engine apis in node.js

## When to choose
- you use Express and want to configure or switch view engines easily
- you need one consistent render API across many template engines
- you are building a framework that should support arbitrary template engines

## When to avoid
- you only use a single template engine and can call it directly
- you need a modern actively developed templating solution
- you rely on engines that are unmaintained or have known security issues

## Facets
- artifact type: library
- maturity: maintenance
- function: templating, middleware
- domain: web-development, frontend, developer-tools
- platform: -
- tags: template-engines, express, view-engine, abstraction-layer, nodejs
