Development Mode

Clone this repo
Run npm i to install dependencies
Start megalinter server npm run start:megalinter
Run npm start
Open codetotal app

Available Scripts

npm start start all projects in development mode
npm run lint lint all projects
npm run build:be build the backend (used by launch.json file for debugging)
npm run start:fe start the FE in development mode
npm test run all unit tests

Config

Add a .env file in the root of the project.
Only variables starting with the CODETOTAL_ prefix will be injected into the frontend bundle.

# FRONTEND
CODETOTAL_UPLOAD_FILE_LIMIT_BYTES=10000000

Building For Production

Config files must be set before the build (see Config section)
Run npm run build at the root folder
This will create a dist folder with the backend code
The frontend code will be under dist/public
Run using npm run production (equivalent to node dist/index.js)

Debugging in VSCode

Add a launch.json file under the .vscode folder with the following content:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Build Project",
      "program": "${workspaceFolder}/packages/backend/dist/index.js",
      "envFile": "${workspaceFolder}/.env",
      "preLaunchTask": "npm: build:be",
      "sourceMaps": true,
      "smartStep": true,
      "internalConsoleOptions": "openOnSessionStart",
      "outFiles": ["${workspaceFolder}/packages/backend/dist/**/*.js"]
    }
  ]
}

Messages from MegaLinter server

Event-based management of MegaLinter Server can send the following list of messages into Redis PUBSUB channel built the following way: megalinter:pubsub:REQUEST_ID

Example: megalinter:pubsub:RQ_cbdd1d82-1e7b-11ee-9258-0242ac120004

Start MegaLinter analysis

This message is sent once by analysis, when a MegaLinter instance has identified the linters to run and is about to start them.

Complete MegaLinter analysis

This message is sent once by analysis, when a MegaLinter analysis is completed.

CodeTotal stops listening to the requestId pubsub channel once this message is received, as no new message will be sent through this channel.

Example of megalinterComplete messageType:

{
  "messageType": "megalinterComplete",
  "megaLinterStatus": "completed",
  "requestId": "RQ_cbdd1d82-1e7b-11ee-9258-0242ac120004"
}

MegaLinter server error

In some cases, it is not possible for MegaLinter to start an analysis because there has been an error during initialization.

In that case, CodeTotal stops listening to the pubsub channel, as no more messages will be sent.

List of errors:

missingAnalysisType: Missing type (snippet, file or repository)
gitCloneError: Unable to clone the repository (probably not existing or not reachable)
uploadedFileNotFound: Unable to find file(s) that were supposed to be uploaded by a previous HTTP call to /upload-file
snippetGuessError: Unable to automatically detect the language of a code snippet
snippetBuildError: Unable to find a file extension for the guessed snipper language

Release Management

Create a sub-branch main branch, name it release/vX.XX.XX (example: release/v1.2.0)

Update CHANGELOG.md to add the section about the content of the new release. Leave empty the beta section, then commit.

Run npm version --no-git-tag-version --new-version vX.XX.XX (example: npm version --no-git-tag-version --new-version v1.2.0)

Commit updates on package.json and package-lock.json with message release vX.XX.XX

Make a Pull Request to main. IMPORTANT: The PR title must contain release in lowercase. Example: New release v1.2.0.

Merge the PR if everything is ok (use Squash & Merge option), else perform linter fixes until jobs are green, then merge.

Create a new GitHub Release -> https://github.com/oxsecurity/codetotal/releases/new
- Input your new version tag string (ex: v1.2.0)
- Name the release CodeTotal vX.XX.XX (ex: CodeTotal v1.2.0)
- Click on Generate Release Notes button
- Arrange the result with content of CHANGELOG.md if necessary (like breaking change instructions)
- Create the GitHub release: An automated job will be triggered and will release the associated CodeTotal Docker Image
