-# Bower {#sec-bower}
-
-[Bower](https://bower.io) is a package manager for web site front-end components. Bower packages (comprising of build artifacts and sometimes sources) are stored in `git` repositories, typically on Github. The package registry is run by the Bower team with package metadata coming from the `bower.json` file within each package.
-
-The end result of running Bower is a `bower_components` directory which can be included in the web app's build process.
-
-Bower can be run interactively, by installing `nodePackages.bower`. More interestingly, the Bower components can be declared in a Nix derivation, with the help of `bower2nix`.
-
-## bower2nix usage {#ssec-bower2nix-usage}
-
-Suppose you have a `bower.json` with the following contents:
-
-### Example bower.json {#ex-bowerJson}
-
-```json
-  "name": "my-web-app",
-  "dependencies": {
-    "angular": "~1.5.0",
-    "bootstrap": "~3.3.6"
-  }
-```
-
-Running `bower2nix` will produce something like the following output:
-
-```nix
-{ fetchbower, buildEnv }:
-buildEnv {
-  name = "bower-env";
-  ignoreCollisions = true;
-  paths = [
-    (fetchbower "angular" "1.5.3" "~1.5.0" "1749xb0firxdra4rzadm4q9x90v6pzkbd7xmcyjk6qfza09ykk9y")
-    (fetchbower "bootstrap" "3.3.6" "~3.3.6" "1vvqlpbfcy0k5pncfjaiskj3y6scwifxygfqnw393sjfxiviwmbv")
-    (fetchbower "jquery" "2.2.2" "1.9.1 - 2" "10sp5h98sqwk90y4k6hbdviwqzvzwqf47r3r51pakch5ii2y7js1")
-  ];
-}
-```
-
-Using the `bower2nix` command line arguments, the output can be redirected to a file. A name like `bower-packages.nix` would be fine.
-
-The resulting derivation is a union of all the downloaded Bower packages (and their dependencies). To use it, they still need to be linked together by Bower, which is where `buildBowerComponents` is useful.
-
-## buildBowerComponents function {#ssec-build-bower-components}
-
-The function is implemented in [pkgs/development/bower-modules/generic/default.nix](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/bower-modules/generic/default.nix).
-
-### Example buildBowerComponents {#ex-buildBowerComponents}
-
-```nix
-{
-  bowerComponents = buildBowerComponents {
-    name = "my-web-app";
-    generated = ./bower-packages.nix; # note 1
-    src = myWebApp; # note 2
-  };
-}
-```
-
-In ["buildBowerComponents" example](#ex-buildBowerComponents) the following arguments are of special significance to the function:
-
-1. `generated` specifies the file which was created by {command}`bower2nix`.
-2. `src` is your project's sources. It needs to contain a {file}`bower.json` file.
-
-`buildBowerComponents` will run Bower to link together the output of `bower2nix`, resulting in a `bower_components` directory which can be used.
-
-Here is an example of a web frontend build process using `gulp`. You might use `grunt`, or anything else.
-
-### Example build script (gulpfile.js) {#ex-bowerGulpFile}
-
-```javascript
-var gulp = require('gulp');
-
-gulp.task('default', [], function () {
-  gulp.start('build');
-});
-
-gulp.task('build', [], function () {
-  console.log("Just a dummy gulp build");
-  gulp
-    .src(["./bower_components/**/*"])
-    .pipe(gulp.dest("./gulpdist/"));
-});
-```
-
-### Example Full example — default.nix {#ex-buildBowerComponentsDefaultNix}
-
-```nix
-{
-  myWebApp ? {
-    outPath = ./.;
-    name = "myWebApp";
-  },
-  pkgs ? import <nixpkgs> { },
-}:
-
-pkgs.stdenv.mkDerivation {
-  name = "my-web-app-frontend";
-  src = myWebApp;
-
-  buildInputs = [ pkgs.nodePackages.gulp ];
-
-  bowerComponents = pkgs.buildBowerComponents {
-    # note 1
-    name = "my-web-app";
-    generated = ./bower-packages.nix;
-    src = myWebApp;
-  };
-
-  nativeBuildInputs = [
-    writableTmpDirAsHomeHook # note 3
-  ];
-
-  buildPhase = ''
-    runHook preBuild
-
-    cp --reflink=auto --no-preserve=mode -R $bowerComponents/bower_components . # note 2
-    ${pkgs.nodePackages.gulp}/bin/gulp build # note 4
-
-    runHook postBuild
-  '';
-
-  installPhase = ''
-    runHook preInstall
-
-    mv gulpdist $out
-
-    runHook postInstall
-  '';
-}
-```
-
-A few notes about [Full example — `default.nix`](#ex-buildBowerComponentsDefaultNix):
-
-1. The result of `buildBowerComponents` is an input to the frontend build.
-2. Whether to symlink or copy the {file}`bower_components` directory depends on the build tool in use.
-   In this case, a copy is used to avoid {command}`gulp` silliness with permissions.
-3. {command}`gulp` requires `HOME` to refer to a writeable directory.
-4. The actual build command in this example is {command}`gulp`. Other tools could be used instead.
-
-## Troubleshooting {#ssec-bower2nix-troubleshooting}
-
-### ENOCACHE errors from buildBowerComponents {#enocache-errors-from-buildbowercomponents}
-
-This means that Bower was looking for a package version which doesn't exist in the generated `bower-packages.nix`.
-
-If `bower.json` has been updated, then run `bower2nix` again.
-
-It could also be a bug in `bower2nix` or `fetchbower`. If possible, try reformulating the version specification in `bower.json`.
