In certain situations the site or app you’re building uses fonts that are not hosted in a CDN. The font is not in Google fonts, and is not in Adobe Fonts or other provider.

You may be given at that point a set of OTF, TTF and WOFF files. But what do do then? How do you integrate those font files in your Buffalo app?. After all, you want your frontend to look as closer to what your designer has put together, And we all know that fonts matter.

What to do?

Assuming you are in your Buffalo app folder, take a look at the assets sub-folder.

  > images

As developers one of our duties is to ensure consistency in how content is displayed in a variety of browsers. If your web development project involves testing the visuals on IE11 or Microsoft Edge and don’t know how because you are using MacOS, then this post is for you! Note that you do not need a serial number or purchase anything in order to install Windows 10.

I’ll expose a fairly simple and popular way to operate Bill Gates' giant having Steve Jobs as host using Oracle’s VirtualBox. The steps are as follows:

1. Install Oracle’s VirtualBox.
2. Install Microsoft 10 using a .iso file in VirtualBox.
3. Testing your project with IE11 and Microsoft Edge.

Disclaimer. Those who are not familiarized with N+1 problem, you can check “What is the N+1 selects problem in ORM(Object-Relational Mapping) with details explaining the concept.

Since associations were introduced in Pop, the N+1 problem became part of it: many queries hit the database in order to load whole model’s associations. Good news is N+1 problem is not a disease without remedy. In this post I will give you some steps I took to solve it by incorporating emergent design.

Step 1: Start Coding By Example

Coding by example helps you to define what’s your input and what’s your output. Code By Example means you define a scenario where  your solution is tested and what is the expected result. The method I used to apply this technique was Test Driven Development (TDD).

Sendgrid is one of the most well-known and used email delivering solutions. It has solutions for most (if not all) of the common email sending and delivering issues that we could face as developers. But this post is not about convincing you to use Sendgrid.

One of the things I love about Buffalo is that it ships with all of the things a product needs for rapid application development and deployment. In this case that is email. Buffalo has a mail package that you can use to integrate sendgrid or any other provider with your app.

import github.com/buffalo/mail

Buffalo’s mail package key items are the Sender interface and the Message struct. It also ships with an SMTPSender implementation of the Sender interface which could be used if you have an SMTP server or want to use your gmail/hotmail email to send emails. I do not recommend you to use a single email account for SMTP on production environments but it could be useful when doing very quick iterations and hacks.

Sender interface

The Sender interface is a very simple interface which is defined as:

Google Cloud Run is a service that allows you to run containerized applications in a serverless environment. This means that you don’t have to care about servers. Billing is done for what you use in terms of memory and processor for time (Google provides a free tier you can check here).

In this post, I will describe how you deploy your Buffalo application to Cloud Run.

Setup

In order for us to be able to send the app to Google Cloud Run, you need:

• Docker installed
• Gcloud CLI tool installed with the beta components
• Gcloud logged into your google account
• Docker setup with your GCR account

A lot of things have changed in the Buffalo ecosystem since my last post on how to deploy to Heroku from Gitlab.

Indeed, everything has changed since I posted how to deploy from gitlab repo into Heroku with the birth of the buffalo-heroku plugin. In this post I will try and describe how to use it to deploy your buffalo app to Heroku.

Setup

First thing you need to install (or ensure you have) is buffalo-plugins plugin. If you’re on buffalo v0.14.6 or higher you’re all set. If you’re on an older version you should:

1. Move to your project root folder
2. Download and install buffalo-plugins plugin

$ GO111MODULE=off go get -u github.com/gobuffalo/buffalo-plugins

Buffalo already ships with very cool pagination support, more than that it even uses the pagination when we generate resources, which is awesome.

I’ve been working lately in a project that uses that pagination (again thanks to the buffalo team), but this app also has a page indicator on the left side, as the following image shows:

Yes, i’m talking about the section that says “Displaying 1 - 25 of 120 Policies” (design typo there).

So my first thought was computing those variables on the action and then passing these to the view, where i would use them to build my “page indicator” section.

As some of you may know, our team has been working with Go for some time and we have always been using CircleCI to run our test suites, we would like to share our circle.yml file, it would help for your Go projects. Enjoy!

In part one I talked about what refactoring is and all stuff related to that. In this post I want to show you how refactorings are related to frameworks and give you a real example of their use.

Frameworks were design to make your life easier in some way, and they should fit to solve your problems. Nowadays developers rarely build apps from scratch, we use frameworks according to our needs to speed up construction, testing and delivery. You realize that get used to a framework doesn’t mean you are except from live without code smells. You can actually apply refactoring techniques using the components and elements those frameworks provide.

To give you an example, last week we were working in an app which was built using Ember.js framework, while we were in a manual code review activity, we found some duplicated code into three route components.
