Runs a js_binary as a build action.

This macro wraps Aspect bazel-lib's run_binary (https://github.com/aspect-build/bazel-lib/blob/main/lib/run_binary.bzl) and adds attributes and features specific to rules_js's js_binary.

Macros and Functions

run_js_binary

Wrapper around @aspect_bazel_lib run_binary that adds convienence attributes for using a js_binary tool.

This rule does not require Bash native.genrule.

Example usage (generated)

load("@aspect_rules_js//js:run_js_binary.bzl", "run_js_binary")

run_js_binary(
    # Target name
    name = "",
    # The tool to run in the action
    tool = None,
)

name

Target name

tool

The tool to run in the action.

Should be a js_binary rule. Use Aspect bazel-lib's run_binary (https://github.com/aspect-build/bazel-lib/blob/main/lib/run_binary.bzl) for other *_binary rule types.

env

Environment variables of the action.

Subject to $(location) and make variable expansion.

srcs

Additional inputs of the action.

These labels are available for $(location) expansion in args and env.

output_dir

Set to True if you want the output to be a directory.

Exactly one of outs, output_dir may be used. If you output a directory, there can only be one output, which will be a directory named the same as the target.

outs

Output files generated by the action.

These labels are available for $(location) expansion in args and env.

args

Command line arguments of the binary.

Subject to $(location) and make variable expansion.

chdir

Working directory to run the binary or test in, relative to the workspace.

This overrides the chdir value if set on the js_binary tool target.

By default, Bazel always runs in the workspace root.

To run in the directory containing the run_js_binary under the source tree, use chdir = package_name() (or if you're in a macro, use native.package_name()).

To run in the output directory where the run_js_binary writes outputs, use chdir = "$(RULEDIR)"

WARNING: this will affect other paths passed to the program, either as arguments or in configuration files, which are workspace-relative.

You may need ../../ segments to re-relativize such paths to the new working directory.

stdout

set to capture the stdout of the binary to a file, which can later be used as an input to another target subject to the same semantics as outs

stderr

set to capture the stderr of the binary to a file, which can later be used as an input to another target subject to the same semantics as outs

exit_code_out

set to capture the exit code of the binary to a file, which can later be used as an input to another target subject to the same semantics as outs. Note that setting this will force the binary to exit 0.

If the binary creates outputs and these are declared, they must still be created

silent_on_success

produce no output on stdout nor stderr when program exits with status code 0.

This makes node binaries match the expected bazel paradigm.

copy_srcs_to_bin

When True, all srcs files are copied to the output tree that are not already there.

log_level

Set the logging level of the js_binary tool.

This overrides the log level set on the js_binary tool target.

kwargs

Additional arguments
