Meteor Blaze Templates done right!

I often hear amazing and simple people find Meteors Blaze render engine, but in the same sentence mention how its difficult to manage large templates or create re-useable components. In my last two+ years working with Meteor I came across the same hurdles, but also found great solutions. So I thought its time to share my best practices in a blog post. Though this post is for advanced user, I want to give new comers a short intro into Meteors. If you’re looking for something specific you can jump right there: Using template-var Passing data around Accessing template vars from inside callbacks Reacting on data context changes Passing data in …

Add better modals to ethereum:elements

ethereum:elements gives you useful elements to make building a dapp more fun. One element, which was there since a while has now got a better API. Instead of realing on iron:router, it uses now a global object called EthElements.Modal to show and hide modals, read below to see how you can make use of them. Note that when you use the modals in combination with the dapp-styles, they look even more awesome! To start just place a modal placeholder before the closing body tag. {{> dapp_modalPlaceholder}} Render without route To render the modal simply call: EthElements.Modal.show(‘myContentTemplate’); // Or with data for the template EthElements.Modal.show({ template: ‘myContentTemplate’, data: { myData: ‘some …

Meteor Build Client

Since more to than 2 years I’ve build Meteor applications. Interestingly I’ve build most of them only using the client part. Working with TunedIn we used a LAMPP stack API, and in my current work I use Meteor to build Ðapps, which don’t have a server in the traditional sense, instead they only talk to the blockchain and get delivered over swarm, a decentralised filesystem. I wrote a while back about using Meteor as frontend library and wrote a little grunt script, which did this. My blog post got more than 3000 hits in just two days, so there seems to be a great interest in that use case. A …

Meteor template animation helper

UPDATE 04.06.2015 Better use the new template animation helper, which uses ui_hooks to start animations: https://atmospherejs.com/frozeman/animation-helper UPDATE 23.10.2013 You can now also pass a template name to the {{AnimateTemplate “…”}} helper, this will render the template in place, switching a hidden class to animate on the element(s) with the class animate. Additionally the data context of this template gets the _templateAnimationKey, so you can manually fade the template out. To do that call the following inside a helper or event of that template: Update made BLAZE ready, the new render engine of meteor View/Session.set(this._templateAnimationKey, false); If you’re inpatient check out atmosphere. I love meteor for its simplicity, but there is …

The Bitcoin Robot

UPDATE After using the robot for a while, i think that its way more efficient to buy bitcoin and leave them as using this robot, or trade manually! So better stay away and put that money in BTC directly Hey, like you probably already read in my about page i’m currently into BITCOIN. I discovered it in may when it was at 80 EUR/BTC and shortly after went up to 266 USD/BTC, to crash then back to 50 and later ~100 USD/BTC. Currently we are at 130 USD/BTC at the time of this writing. I love the idea and the concept of bitcoin and already digged into wallets and addresses, …

Using Meteor as frontend library!

UPDATE You can now use my CLI to get the client part of your Meteor app! If you’re impatient go here: https://github.com/frozeman/MeteorFrontend Meteor is awesome, i loved it immediately as i saw the video. The way you can build one page apps is absolutely intuitive. I struggled with Ember.js, Backbone.js and AngularJS (which clutter the HTML too much), but Meteor really got it, in my opinion. The problem with Meteor is that it forces you to use the full-stack. Natively there is currently no easy way to separate the frontend from the server in Meteor. As i’m using Meteor to build the awesome TunedIn WebApp and we have already an …
