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.

Unix:
./node_modules/.bin/slnodejs scan --tokenfile /path/to/sltoken.txt --buildsessionidfile buildSessionId --workspacepath "." --scm git --es6Modules

Windows:
call .\node_modules\.bin\slnodejs scan --tokenfile \path\to\sltoken.txt --buildsessionidfile buildSessionId --workspacepath "." --scm 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 https://sealights.atlassian.net/l/c/n6GuFwok
For "JavaScript heap out of memory" errors while running scan, see: https://sealights.atlassian.net/wiki/spaces/SUP/pages/561905721

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.

Unix

./node_modules/.bin/slnodejs scan --tokenfile /path/to/sltoken.txt --buildsessionidfile buildSessionId --workspacepath "." --scm git --es6Modules --uniqueModuleId module-name-one 
./node_modules/.bin/slnodejs scan --tokenfile /path/to/sltoken.txt --buildsessionidfile buildSessionId --workspacepath "." --scm git --es6Modules --uniqueModuleId module-name-two

./node_modules/.bin/slnodejs buildend --tokenfile /path/to/sltoken.txt --buildsessionidfile buildSessionId --ok

Windows

call .\node_modules\.bin\slnodejs scan --tokenfile \path\to\sltoken.txt --buildsessionidfile buildSessionId --workspacepath "." --scm git --es6Modules --uniqueModuleId module-name-one
call .\node_modules\.bin\slnodejs scan --tokenfile \path\to\sltoken.txt --buildsessionidfile buildSessionId --workspacepath "." --scm git --es6Modules --uniqueModuleId module-name-two

call .\node_modules\.bin\slnodejs buildend --tokenfile \path\to\sltoken.txt --buildsessionidfile buildSessionId --ok
