Interpol View Engine for Node.js Web Frameworks
``bash`
npm install interpol-views --save
`javascript`
app.engine('int', require('interpol-views').__express);
app.set('view engine', 'int');
If Express is started in development mode, the view engine will monitor the default views directory (usually ./views) and continuously reload any modified files ending in .int. Obviously this will incur quite a bit of processing overhead, so should be avoided for production deployments.
If Express is started with any NODE_ENV other than 'development' (or nil), the engine will not monitor the directory for changes.
The Interpol command-line interface generates pre-compiled JavaScript. You can install this globally using npm -g install interpol and can then invoke the tools at your terminal by typing interpol.
If you're interested in deploying using only pre-compiled JavaScript, you will need to configure a view engine that does not perform compilation. This can be done in Express like so:
`javascript`
var interpolViews = require('interpol-views');
var viewEngine = interpolViews.createExpressEngine({
compile: false // read .int.js files rather than .int files
});
app.engine('int', viewEngine);
app.set('view engine', 'int');
After that, just launch the interpol command-line against your views directory:
`bash`
interpol -in ./views
`javascript`
server.views({
engines: {
int: {
module: require('interpol-views'),
compileOptions: {
importPath: viewsPath
}
}
},
path: viewsPath
});
The importPath property must be specified if you intend to perform import` calls, otherwise it is optional. The reason that it's required is that Interpol will be resolving modules internally, and there was no other way for the view engine to determine the configured view path.
