    install-files

    This module lets you share files between projects, e.g. configuration files.

    Why not Git submodules?

    install-files lets you install files at the root directory of a project, whereas submodules can only install files in subdirectories.

    install-files also merges files into existing directories, and lets you customize those directories thereafter, whereas you'd have to fork a submodule to make custom modifications.

    Lastly, install-files lets you share files between Node projects the same way you would share code, using npm and declarative package names/versions.

    Example

    Let's say you want to share some .ebextensions files between several Node microservices. To do that with install-files, you'd make a package with those files, let's call it my-ebextensions, with the following directory structure and package.json:

    my-ebextensions/
      node_modules/
      source/
        .ebextensions/
          foo.config
      package.json
    
    {
      "name": "my-ebextensions",
      "scripts": {
        "install": "install-files source"
      },
      "dependencies": {
        "install-files": "^1.0.0"
      }
    }
    

    Then, when you install my-ebextensions into my-microservice, it will copy the contents of my-ebextensions/source/ into my-microservice/, where you can commit them as appropriate.

    Before installing my-ebextensions:

    my-microservice/
      node_modules/
      index.js
      package.json
    

    After installing my-ebextensions:

    my-microservice/
      .ebextensions/
        foo.config
      node_modules/
      index.js
      package.json
    

    Installation

    npm install install-files --save

    You install install-files into the package with the files to install, as per the example.

    You should recommend that the package with the files to install is installed as a dev dependency (npm install my-ebextensions --save-dev, for example) so that it does not try to install the files in a production environment. The files should have been installed and committed prior to then (when the package was installed locally), so this work should be redundant.

    It is recommended that you set the CI environment variable when npm installing in CI if your CI environment is a development environment where you don't want to run install-files.

    (in project where this module is a transitive dependency; in your CI configuration)

    CI=true npm install
    

    Usage details

    For a quick run-down, see the example. More details:

    install-files source will recursively merge source/ into the host package's directory (my-microservice/ in the example), creating subdirectories if necessary. It will not replace pre-existing files, including in subdirectories, unless source/ contains files with the same name.

    For instance, if my-microservice/.ebextensions/ already contained bar.config, install-files source would not overwrite that. However, install-files source would overwrite foo.config.

    This overwriting behavior lets the file-installing package interoperate with other, project-specific files, yet control its "own" files.

    Updating the installed files

    Modifications to the files should be made by updating the file-installing package, not by editing the copies.

    Update the originals in the file-installing package, then push a new version of the package. When npm update is run in the dependent package, the changes will be copied over.

    install-files will not prune files that have been removed from source/. If you feel that it should and have ideas about how to do it, please open an issue!
