NPM install measure slow deps install time

Cory Robinson — Mon, 13 Sep 2021 22:59:54 +0000

When you have slow npm install times and you're sure it's not connection related, check which npm packages are the slowest and leading to your slow installs:

npm install -g slow-deps

Then, run: slow-deps in the project directory.

📱Android - How does your team 👉 DEV -> QA -> Release ❓

Cory Robinson — Wed, 10 Feb 2021 20:56:10 +0000

This post will outline our current process for mobile development on an Android app. Hopefully it will instigate discussion and responses on how other teams have implemented this software development lifecycle.

How our team ships Android apps (software development lifecycle):

Developer checks out a feature branch to do work
Developer pushes branch up, jenkins builds an apk with the feature branch name in the filename [feature branch name].apk
QA team downloads and sideloads this feature branch apk to run on their Android device
If QA passes, the developer merges the feature branch into master branch
To make an app store release, the developer checks out a release branch from master, bumps the versionCode and versionName values, builds an apk and uploads for a Play Store release

This process requires a lot of manual installing/uninstalling of Android .apk's but it is reliable for separating builds and features for testing.

Does your team have a different way for Android software development lifecycle?

Custom Jest Snapshots Directory Setup

Cory Robinson — Thu, 05 Mar 2020 04:31:49 +0000

When you want to place your component test files right next to the component's but you don't want your directories littered with __snapshots__/ dirs:

// __snapshots__/snapshotResolver.js

module.exports = {
  resolveSnapshotPath: (testPath, snapshotExtension) =>
    testPath
      .replace(
        /\.test\.([tj]sx?)/, 
        `.test${snapshotExtension}`
      )
      .replace(
        /src([/\\]components)/, 
        '__snapshots__'
      ),

  resolveTestPath: (snapshotFilePath, snapshotExtension) =>
    snapshotFilePath
      .replace(snapshotExtension, '.js')
      .replace('__snapshots__', 'src/components'),

  testPathForConsistencyCheck: 'src/components/some.test.js',
}

// jest.config.js

module.exports = {
  preset: 'react-native', // optional depending on your project

  snapshotResolver: './__snapshots__/snapshotResolver.js',

  testMatch: [
    '**/__tests__/**/?(*.)+(spec|test).(js|ts|tsx)', 
    '**/?(*.)+(spec|test).(js|ts|tsx)'
  ],
}
