Development

Using the example project (easy)

There is an example TodoMVC project in /examples/todomvc in this repo. It is a pretty basic application, but in many cases it is all you need to work on re-frame-10x.

$ cd examples/todomvc
$ npm install
$ npx shadow-cljs watch app

Setting up re-frame-10x for development (more advanced)

If you want to test and develop re-frame-10x against your own re-frame projects, you will need to do some more advanced setup using the leiningen checkouts feature.

You need both the re-frame-10x project and a test project to develop it against. For example, you can use the todo-mvc project in the re-frame repo.

  • Clone re-frame-10x to your machine:

    git clone [email protected]:day8/re-frame-10x.git

  • Go into the root folder of the test project you're using to develop re-frame-10x with.

    cd /your/project/folder

  • Add re-frame-10x into this test project using the instructions above.

  • Still in the test project, create a folder called checkouts, then enter the folder:

    mkdir checkouts
cd checkouts

  • Create a relative symlink from your local re-frame-10x project in the checkouts folder. For example:

    ln -s ../relative/path/to/your/local/re-frame-10x re-frame-10x

mklink /d /j re-frame-10x ..\relative\path\to\your\local\re-frame-10x [Windows]

  • If you're using figwheel in the test project, you need to add the checkouts folder (checkouts/re-frame-10x/src) to :cljsbuild :source-paths in the project.clj file. If you're having trouble locating the right place to put this, it might help to look to a sample project.clj for inspiration. For example:

    :cljsbuild {:builds {:client {:source-paths ["checkouts/re-frame-10x/src"]}}}

  • re-frame-10x has a debug panel useful when developing it. You can enable it by adding the :closure-define "day8.re_frame_10x.debug_QMARK_" true to your compiler settings.

  • Now run your test project however you usually run it, and re-frame-10x should be in there. \o/

Developing CSS

The styles for the trace panel are defined both inline and in Garden styles in day8.re-frame-10x.styles.

We are using CSS preprocessing to isolate the panel styles, by namespacing the panel styles with the id #--re-frame-10x--.

Problems while developing CSS

  • Try clearing your browser cache/hard-reloading.

Updating the internal version of re-frame used

We want to use re-frame, but we don't want to use the re-frame that the host is using, or tracing will get very messy. Instead, we use mranderson to create source dependencies of re-frame and reagent.

Run ./source-deps.sh to update the source dependencies.

How does re-frame-10x build?? I don't see anything in the project.clj that looks like it will build.

When you add a path to the :source-paths of the test project used to develop the trace panel against, figwheel in the test project will know to watch and build it too.

I'm developing against the re-frame todomvc project. Why are changes in my local re-frame repo reflected in the example project? Shouldn't it be pulling from clojars?

The re-frame todomvc depends on the source paths of the re-frame project in the same repo. It does this by adding adding "../../src" to :source-paths.
