Code Climate

The continuous integration process for our Rails backend app starts by opening a GitHub pull request. This triggers a CircleCI build and some Code Climate checks.

The CircleCI build is a workflow that runs the following jobs:

• check for security vulnerabilities with Brakeman
• check code quality with RuboCop
• run RSpec tests in parallel with the knapsack gem, and output test coverage reports with the simplecov gem
• upload test coverage to Code Climate

Code Climate checks the following:

• code quality metrics like code complexity
• test coverage minimum thresholds

The CircleCI jobs and Code Climate checks above have corresponding GitHub status checks.

Once all the mandatory GitHub checks pass and the code+functionality have been reviewed, developers can merge their pull request into our Git master branch. Code is then ready to deploy!

#ContinuousIntegration

When I first built my portfolio I used GitHub for the source control and deployed directly to Netlify on a push to master. This was a perfect setup, I didn't need any knowledge about #DevOps or anything, it was all just done for me.

One of the issues I had with Netlify was I wanted to gzip my JavaScript files, I had this setup in my #Webpack file, however Netlify didn't offer an easy way to set this.

Over the weekend I decided I wanted to know more about how #DevOps worked so I decided to switch from Netlify to Amazon S3. Instead of creating any #Git Webhooks I decided to use Buddy for my pipeline and to run commands. Buddy is a fantastic tool, very easy to setup builds, copying the files to my Amazon S3 bucket, then running some #AWS console commands to set the content-encoding of the JavaScript files. - Buddy is also free if you only have a few pipelines, so I didn't need to pay anything 🤙🏻.

When I made these changes I also wanted to monitor my code, and make sure I was keeping up with the best practices so I implemented Code Climate to look over my code and tell me where there code smells, issues, and other issues I've been super happy with it so far, on the free tier so its also free.

I did plan on using Amazon CloudFront for my SSL and cacheing, however it was overly complex to setup and it costs money. So I decided to go with the free tier of CloudFlare and it is amazing, best choice I've made for caching / SSL in a long time.

We use it as part of CI process to check code quality, to ensure that we're not inadvertently making common mistakes and can keep the smells and scope of code changes in line and clean. Having this step here should make future support and additions much more efficient and easy to understand. Code Climate
