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 --workspacepath "." --scm git --es6ModulesFor 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 Using Node.js Agent - Ignoring Files or Folders - Support - Sealights
For "
JavaScript heap out of memory" errors while running scan, see: NodeJS - JavaScript heap out of memory
See 'Node.js Command Reference - Scanning a build' for full parameter details
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.
npx slnodejs scan --tokenfile ./path/to/sltoken.txt --buildsessionidfile buildSessionId --workspacepath "." --scm git --es6Modules --uniqueModuleId module-name-one
npx slnodejs scan --tokenfile ./path/to/sltoken.txt --buildsessionidfile buildSessionId --workspacepath "." --scm git --es6Modules --uniqueModuleId module-name-two
npx slnodejs buildend --tokenfile ./path/to/sltoken.txt --buildsessionidfile buildSessionId --ok
