Less rules for Bazel
WARNING: this is beta-quality software. Breaking changes are likely. Not recommended for production use without expert support.The Less rules run the Less CSS preprocessor with Bazel.
Installation
Add the@bazel/less npm package to your devDependencies in package.json.Your
WORKSPACE should declare a yarn_install or npm_install rule named npm.
It should then install the rules found in the npm packages using the install_bazel_dependencies function.
See https://github.com/bazelbuild/rulesnodejs/#quickstartThis causes the
@bazel/less package to be installed as a Bazel workspace named npm_bazel_less.Installing with self-managed dependencies
If you didn't use theyarn_install or npm_install rule to create an npm workspace, you'll have to declare a rule in your root BUILD.bazel file to execute less:# Create a less rule to use in less_binary#compiler
# attribute when using self-managed dependencies
nodejs_binary(
name = "less_bin",
entry_point = "//:node_modules/less/bin/lessc",
# Point bazel to your node_modules to find the entry point
node_modules = ["//:node_modules"],
)lessbinary
Usage
less_binary(name, compiler, deps, sourcemap, src)name
(name, mandatory): A unique name for this target.compiler
(label): Label that points to the lessc binary to run.If you install your npm packages to a workspace named something other than "npm",
you may need to set this to `@my_npm_name//@bazel/less/bin:less`
