Hi I'm new to node and I'm trying to figure out how to compile partials from a file into a string using doT.js (http://olado.github.io/doT/index.html).
/controllers/system/index.js:
var util = require( 'util' ),
fs = require( 'fs' ),
dot = require( 'dot' );
function System( ) {
this.name = 'system';
}
System.prototype._loadFile = function( path, def ) {
var def = def || { },
tpl, str;
str = fs.readFileSync( process.argv[ 1 ].replace( /\/[^\/]*$/, path ) );
tpl = dot.compile( str );
str = tpl( def );
return str;
};
System.prototype._getHeaderContent = function( ) {
return this._loadFile( '/controllers/system/views/header.html', {
name: this.name
});
};
System.prototype._getBodyContent = function( ) {
return this._loadFile( '/controllers/system/views/main.html' );
};
System.prototype._getFooterContent = function( ) {
return this._loadFile( '/controllers/system/views/footer.html' );
};
System.prototype.index = function( req, res, next ) {
res.render( __dirname + '/../system/views/template', {
header: this._getHeaderContent( ),
body: this._getBodyContent( ),
footer: this._getFooterContent( )
});
next ? next( ) : '';
};
module.exports = System;
/controllers/system/views/template.html:
{{=it.header}}
{{=it.body}}
{{=it.footer}}
/controllers/system/views/header.html:
<!doctype html>
<html lang="en">
<head>
<title>app | {{=it.name}}</title>
</head>
<body>
In System.index when I call res.render template.html is being compiled but header.html is not. From that I assume render doesn't recursively render files and I need to manually compile header.html before I pass it in to res.render.
I found this tutorial: http://olado.github.io/doT/tutorial.html#compile but both .template and .compile return functions? Attempting to pass them in to res.render throws an error.
How do I compile them into strings? Or am I going about this the wrong way?
Thanks!
Update- fixed and updated with working code thanks Andreas Hultgren!
