MNLA is a wrapper for the Manila template engine that provides universal (isomorphic) rendering and client-side data binding. It adds only 2.5KB of client-side code and 2KB of server-side code on top of the Manila template engine, which is 4KB of server-side code.
npm install mnla --save
This documentation assumes you are using Express.
You can demo the Hello World yourself:
git clone https://github.com/mgrahamjo/mnla && cd mnla/hello-world && npm install && node index
// index.js
const express = require('express'),
app = express(),
mnla = require('mnla')();
app
// Define the location of your static assets:
.use(express.static('assets'))
// If you aren't using a bundler like Browserify,
// add a static route for the MNLA source code:
.use(express.static('node_modules/mnla'))
// Tell Express to use the MNLA template engine:
.engine('mnla', mnla)
.set('view engine', 'mnla')
// Set up some routes:
.get('/', require('./controllers/index'))
.get('/message', require('./controllers/message')) // JSON endpoint
// Start the app
.listen(1337, () => {
console.log('Listening on localhost:1337');
});
// controllers/message.js
// Here is a controller for the json endpoint /message.
module.exports = (req, res) => {
res.json({
message: "hello, world!"
});
};
// controllers/index.js
const manila = require('mnla/server');
module.exports = (req, res) => {
manila({
// Here we define our component names and underlying data sources:
// You can pass a json endpoint as a data source:
message: require('./message'),
// Or you can pass raw data:
input: {
message: "hello, world!"
},
// If you wanted to set up a client-side component
// that isn't rendered on the server side, you would pass null
// clientComponent: null
},
// Don't forget to pass req and res (the 'message' controller we included expects them)
req, res)
.then(templateData => {
res.render('index', templateData);
});
};
<!-- views/message.mnla -->
<!-- This is the template for the message component -->
<h1><:message:></h1>
<!-- views/input.mnla -->
<!-- This is the template for the input component -->
<!-- 'on' is a special method that you can use to listen to DOM events. -->
<!-- 'updateMessage' is a custom handler that we'll define in a client side script. -->
<input type="text" <:on('input', updateMessage):> value="<:message:>" />
<!-- views/index.mnla -->

<!-- since we've set up the 'message' and 'input' components, we can render them thusly: -->
<::component.message::>
<::component.input::>
<!-- to allow client-side data binding, include this at the end of the body: -->
<::clientData::>
<!-- and don't forget your client side scripts: -->
<script src="/dist.js"></script> <!-- this is from the node_modules/mnla folder -->
<script src="/js/app.js"></script> <!-- this is from the assets folder -->
</body>

manila
.component('message', vm => {
// When this runs, vm (view model) is already populated with the properties
// that the 'message' controller set on the server side.
// You can add additional methods and properties to vm here.
// Return an object with methods that can be called by other components.
return {
update: message => {
vm.message = message;
}
};
})
.component('input', vm => {
// Here we define the updateMessage method we used in the template as an event listener.
vm.updateMessage = event => {
// Inform the message component of the new value using the 'update' method we created.
manila.components.message.update(event.target.value);
};
});
Now you can run node index, and open up http://localhost:1337. The html is populated with the "hello, world!" message even before the client side javascript runs, and it stays up-to-date as you update the input.
