Question
Your team is working on a Dynamics 365 Commerce project and has encountered a ‘JavaScript heap out of memory’ build error.
You need to increase the Node memory size to prevent this error during the build process.
How should you specify the environment variable?
Select only one answer.
A. Update the ‘yarn msdyn365 pack’ command in the PowerShell build task to allocate more memory.
B. Install a newer version of Node.js that has increased memory capabilities.
C. Manually set the environment variable on each developer’s machine before building.
D. Modify the ‘build’ script in the package.json file to include ‘–max_old_space_size4096’.
Answer
D. Modify the ‘build’ script in the package.json file to include ‘–max_old_space_size4096’.
Explanation
Option D is correct because modifying the ‘build’ script in the package.json file with ‘–max_old_space_size4096’ is the recommended way to increase the Node memory size. Option A is incorrect as the ‘yarn msdyn365 pack’ command does not control memory allocation. Option B is incorrect because simply installing a newer version of Node.js does not address the memory allocation issue. Option C is incorrect as manually setting the environment variable on each developer’s machine is not scalable or reliable.
