template-resolver

Resolves env variables & inline shell commands in static files. Features:

• Resolves env variables in files in the form of ${ENV_VAR}
• Runs inline shell commands in files in the form of $(command)
• Runs inline shell commands in files in the form of `command`
• Resolves & inlines imports in the form of import './child'

Usage

Command Line

Use the command template-resolver or tmpl.

cat myfile.tmpl | template-resolver > result.txt

echo 'current env is ${NODE_ENV}' | tmpl
current env is development

echo 'our system arch is `uname -p`' | tmpl
current env is i386

echo 'our system name is $(uname -s)' | tmpl
current env is Darwin

Node API

var resolver = require('template-resolver');
var content = 'our system is "$(uname -s) `uname -p`" under ${NODE_ENV} env';

resolver(content).then((result)=> {
    result //= our system is "Darwin i386" under development env
});

Imports

Any import statements encountered in a file will be recursivly inlined inside the importing file. By default import paths will be resolved relative to the CWD but can be specified via the -c dir cli argument or as the second argument passed to the node API.

Example

└─ dir/main
   ├─ dir/children/one
   └─ dir/children/two

./dir/main

this is main file and these are my children:
    import './children/one'
    import './children/two'

Command Line

cat ./dir/main | template-resolver -c ./dir

Node API

require('template-resolver')(content, './dir')
