# the race detector, you can manually add it using the ESBUILD_RACE environment

# enable it by adding "export ESBUILD_RACE=-race" to your shell profile.

# Build a custom version of the Go compiler that omits buildinfo from the
# final executable (since there is no command-line option to disable this).
# This is done in an attempt to avoid poorly-implemented "security" tools
# from breaking esbuild for users solely on the basis of what version of
# Go esbuild was compiled with.
#
# Most (all?) Go-related security tooling effectivelly runs the command
# "go version ./esbuild" and then creates a false-positive report for
# esbuild for every single CVE in Go's expansive standard library. There is
# no consideration for whether or not the corresponding API is ever actually
# used by esbuild. These reports are harmful to users as they prevent users
# from using esbuild in enterprise environments where these tools are
# mandatory.
#
# These reports are all false-positives because esbuild is not a security
# boundary. It's just a tool to transform trusted text (your source code)
# into other text, and a local development server that serves a read-only
# view of your source code and is not intended for production use.
