This step by step guide will help you set up BundleMon with CodeFresh

For this guide I used this repo: https://github.com/Yog9/SnapShot

git clone https://github.com/Yog9/SnapShot

yarn build

yarn add -D bundlemon

Create a file new file .bundlemonrc.json

{
  "baseDir": "./build",
  "files": [
    {
      "path": "index.html"
    },
    {
      "path": "static/js/*.chunk.js",
      "maxPercentIncrease": 10
    },
    {
      "path": "static/js/runtime-main.*.js",
      "maxSize": "1kb"
    }
  ]
}

yarn bundlemon

Changing app code will cause webpack to generate a new hash for files that have been changed.

main.e0277e23.chunk.js -> main.c2a935b4.chunk.js

In order for BundleMon to know it's the same file you need to add <hash> string to file path config:

{
  "baseDir": "./build",
  "files": [
    {
      "path": "index.html"
    },
    {
      "path": "static/js/*.<hash>.chunk.js",
      "maxPercentIncrease": 10
    },
    {
      "path": "static/js/runtime-main.<hash>.js",
      "maxSize": "1kb"
    }
  ]
}

• Create new pipeline in CodeFresh
• Add GIT triggers:
  • PR trigger:
    • trigger name: PR
    • trigger by: Pull request opened & Pull request synchronized
  • main branch trigger:
    • trigger name: main-push
    • trigger by: Push commits
    • branch: /^((main)$).*/gi

version: "1.0"

steps:
  main_clone:
    title: "Cloning repository"
    type: "git-clone"
    repo: "${{CF_REPO_OWNER}}/${{CF_REPO_NAME}}"
    revision: "${{CF_REVISION}}"
    git: "github"

  install:
    title: "Install dependencies"
    image: "node:14"
    environment:
      - NPM_CONFIG_CACHE=${{CF_VOLUME_PATH}}/.cache/npm
      - YARN_CACHE_FOLDER=${{CF_VOLUME_PATH}}/.cache/yarn
    commands:
      - yarn

  build:
    title: "Build"
    image: "node:14"
    commands:
      - yarn build

  bundlemon:
    title: "Run BundleMon"
    image: "node:14"
    environment:
      - BUNDLEMON_PROJECT_ID=${{BUNDLEMON_PROJECT_ID}}
      - BUNDLEMON_PROJECT_APIKEY=${{BUNDLEMON_PROJECT_APIKEY}}
    commands:
      - yarn bundlemon

  deploy:
    title: "Deploy"
    image: "node:14"
    commands:
      - echo "deploy..."
    when:
      branch:
        only:
          - main

In order to save history and get differences from your main branches you will need to create a new project and setup environment variables.

• Create new project and copy the project ID and API key
• Add BUNDLEMON_PROJECT_ID & BUNDLEMON_PROJECT_APIKEY to pipeline variables

API key is a secret, encrypt the secret in CodeFresh UI when adding this variable

• Install BundleMon GitHub App

• Add output configuration to BundleMon config

"reportOutput": [
  [
    "github",
    {
      "checkRun": false,
      "commitStatus": true,
      "prComment": true
    }
  ]
],

You can change github output options

When creating your first PR with BundleMon you should see all files found by BundleMon as "Added", because there isn't a record on your main branch.

Once you merge the PR BundleMon will keep a record on your main branch, so on your next PR you should see the difference between the PR and your main branch.
