Scanning a Build

To collect coverage information, SeaLights agents must scan the javascript files for the build information.

Scanning a build

Scanning a build in Node.js is done using the Node.js Build scanner with the build flag.

npx slnodejs scan --tokenFile ./sltoken.txt --buildSessionIdFile buildSessionId --scanDir "." --scmType git --es6Modules

For React applications, you should add the flag: --babylonPlugin jsx. To scan both .ts and .tsx files, you should add the flag: --babylonPlugins typescript,jsx

• In order to ignore specific files or folders during the Scan operation, please refer to Ignoring Files or Folders

• For "JavaScript heap out of memory" errors while running scan, see: NodeJS - JavaScript heap out of memory

• See Scanning a build for full parameter details

Scanning a ts-node build

Scanning a build in Node.js is done using the Node.js Build scanner with the scan command flag and requires:

• explicit type of files (.ts and/or .tsx) in a dedicated environment variable SL_fileExtensions

• scan the application files with the --scanDir parameter pointing to the source files directory (.ts)

Unix

export SL_fileExtensions=".ts,.tsx"

npx slnodejs scan --tokenFile /path/to/sltoken.txt --buildSessionIdFile buildSessionId --scanDir "./src" --scmType git 

Windows

Scanning multi modules

If you want to report separate parts of the application as separate modules, you can do so by scanning each part with the --uniqueModuleId option.

When you finish reporting all the modules, you need to send the event with the buildend command and either the --ok or --failed depending on the result of your build process.

It is important to always use the exact same module names each time you report a new build.

npx slnodejs scan --tokenFile ./path/to/sltoken.txt --buildSessionIdFile buildSessionId --scanDir "." --scmType git --es6Modules --uniqueModuleId module-name-one 
npx slnodejs scan --tokenFile ./path/to/sltoken.txt --buildSessionIdFile buildSessionId --scanDir "." --scmType git --es6Modules --uniqueModuleId module-name-two

npx slnodejs buildend --tokenFile ./path/to/sltoken.txt --buildSessionIdFile buildSessionId --ok
