# For more details on which node_modules files are causing the slowdown, refer to the tsc tracing guide:
# https://github.com/microsoft/TypeScript-wiki/blob/main/Performance-Tracing.mdThis command will generate a trace of the tsc execution and then print a bar graph of the slowest packages to type check.
