template-copy

Tiny scaffolding engine

Like cp, but with Lodash templates

Install

npm i template-copy

Usage

const t = require('template-copy');
 
t('index.html templates/ ~/.config/templates/ava/ test/');
  .catch((err) => {
    console.log('ERR', err);
  })
  .then(() => {
    console.log('done');
  });

Description

File copy is done using Streams, with lodash.template parsing files if they have template placeholders {{ ... }}.

Handlebars template are executed in the context of the following object:

Object.assign({}, env, opts)
 
// where `env` and `opts` have the following structure
 
{
  env: {
    PATH: '...',
    ...
  },
 
  opts: {
    debug: true,
    name: 'Foobar'
  }
}

The templates context is a merged version of various sources, with the following order of precedence:

• opts - Command line flags as parsed by minimist
• env - process.env variables begining with hcp_
• prompts - Generated prompts, see below

Prompts

Handlebars templates can have any number of placeholders. Variables are either available in the context object, or automatically prompted for the user to enter a value.

Skipping a prompt is then available with --name Value.

To enable it, inquirer must be installed and available in node_modules.

npm i inquirer -D

If not installed, prompts are not generated.

JSON

JSON files are merged together with destination, if it already exists.
