Generate nix expressions to fetch bower dependencies.
usage: bower2nix [-h] [-v] [INPUT] [OUTPUT]
Generate nix expressions to fetch bower dependencies
Positional arguments:
INPUT The bower.json file (default: ./bower.json)
OUTPUT The output file to generate (default: stdout)
Optional arguments:
-h, --help Show this help message and exit.
-v, --version Show program's version number and exit.
The easiest way to install bower2nix
is not to install it at
all. Just start a nix-shell
:
nix-shell -p nodePackages.bower2nix
If you have a bower.json
file like this:
{
"name": "bower-test",
"dependencies": {
"angular": "~1.4.0"
}
}
Then running bower2nix bower.json bower-generated.nix
will generate
something like this:
# bower-generated.nix
{ fetchbower, buildEnv }:
buildEnv { name = "bower-env"; ignoreCollisions = true; paths = [
(fetchbower "angular" "1.4.9" "~1.4.0" "0a2754zsxv9dngpg08gkr9fdwv75y986av12q4drf1sm8p8cj6bs")
]; }
The resulting derivation is a union of all the downloaded bower packages (and their dependencies).
Usually, you want a bower_components
directory. This can be
generated with bower install
by pointing it at the environment of
downloaded bower packages.
bowerComponents = pkgs.buildBowerComponents {
name = "bower-test";
generated = ./bower-generated.nix;
src = mySources;
};
The resulting derivation contains a bower_components
directory which
is ready to use in your project's build process.
There is a small example within the example
subdirectory of this repo.
For more information, see the Nixpkgs manual.
For testing purposes, a single package can be downloaded. For example:
fetch-bower angular '~1.4.0' '1.4.8'
. If no output directory is
provided, the package attributes will be shown, and the package
contents discarded.
usage: fetch-bower [-h] [-v] [--out DIR] NAME [TARGET] [VERSION]
Fetch a single bower dependency
Positional arguments:
NAME Package name
TARGET Target version range
VERSION Exact package version
Optional arguments:
-h, --help Show this help message and exit.
-v, --version Show program's version number and exit.
--out DIR, -o DIR Output directory
bower2nix
requires Node.js 4.x or higher. The latest version of
bower2nix
is in the 16.09 release of nixpkgs/NixOS, so use that.
