Recently I worked on upload button feature using ActiveStorage::DirectUpload
features of the Ruby on Rails web framework. There’s nothing too fancy here, but
I got fascinated how nice it was to implement upload progress bar with the help
of modern CSS features.
I recently used Hugo Pipes to optimize asset handling in this site
and replaced old Webpack based hack I had used to achieve same.
That hack was done in the times of Hugo version 0.3x. Currently all necessary
things like JS bundling, CSS pre- and post-processing, fingerprinting,
minification, etc is possible with Hugo native features:
I recently had to implement Rails application monitoring using CloudWatch in a
work project. App in question had multiple integrations to other REST services
so it made sense to be able track their response times, error status counts etc
to better debug performance anomalies.
When developing dockerized services with other communication end-points than
browser client one soon needs some ways to capture and debug network traffic
from containers. Here’s some tools and tips I’ve been using.
Hugo is a blazing fast static site generator with a great
architecture for managing content. However asset pipeline à la
Middleman or Jekyll is something I have been
missing especially for generating images with cache busting hashes in the
filenames.
I solved that by configuring Webpack for something similar.
This is an update to earlier post where MessagePack body
was parsed to controller params using Rack middleware. That approach
relied on ActionDispatch::ParamsParser which got deprecated in 5.1 while
custom mime type params parsing got simpler.
During holidays I finished book CSS Secrets by Lea Verou. I think its the best CSS book I have encountered. It presents 47 everyday design problems with well thought out alternative solutions using latest CSS features.
First chapter gives short introduction on how CSS standards are formed and presents some best practices for writing CSS. That introduction chapter itself changed the way how I have been thinking the DRY principle regarding CSS.
Update ActionDispatch::ParamsParser has been deprecated in Rails 5.0.
Below solution works for Rails versions before 5.1 where ActionDispatch::ParamsParser got removed.
Checkout this post for similar implementation in current Rails versions.
Recently I had to develop Ruby on Rails app which would handle MessagePack formatted request bodies as well as JSON. By default Rails makes parsed JSON available at the params object, and I wanted MessagePack content to be handled just like that.
I had a little bumps along the way following
react-native’s OSX only instructions while setting up
development environment on my Fedora 22 system, so here’s quick notes how I got
it up and running.
