From 853d93db4c81ebb23e354ec36aceddc48d1b1ccc Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 23 Mar 2026 09:08:32 +0000 Subject: [PATCH 1/2] Move demo app to example/ directory The demo handlers (elli_openapi_demo, user_handler) and demo.escript were mixed into src/ alongside the library code. This separates them into a standalone example/ app with its own rebar.config (path dep on parent). Tests still compile elli_openapi_demo via extra_src_dirs in the test profile. CI now also compiles the example app. README updated to guide users to example/. https://claude.ai/code/session_018fWKyeGN93ZDdLR3PyW5Yj --- .github/workflows/ci.yml | 3 +++ README.md | 17 ++++++++---- demo.escript | 27 ------------------- example/demo.escript | 31 ++++++++++++++++++++++ example/rebar.config | 10 +++++++ example/src/demo.app.src | 5 ++++ {src => example/src}/elli_openapi_demo.erl | 0 {src => example/src}/user_handler.erl | 0 rebar.config | 8 ++---- 9 files changed, 63 insertions(+), 38 deletions(-) delete mode 100644 demo.escript create mode 100644 example/demo.escript create mode 100644 example/rebar.config create mode 100644 example/src/demo.app.src rename {src => example/src}/elli_openapi_demo.erl (100%) rename {src => example/src}/user_handler.erl (100%) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index cf14738..f210d06 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -51,6 +51,9 @@ jobs: - name: Compile run: make compile + - name: Compile example + run: cd example && rebar3 compile + - name: Run tests run: make test diff --git a/README.md b/README.md index 08d31c9..8cfdad2 100644 --- a/README.md +++ b/README.md @@ -31,7 +31,7 @@ ElliOpts = [ {ok, Pid} = elli:start_link(ElliOpts). ``` -See `src/elli_openapi_demo.erl` for example handler implementations. +See the `example/` directory for a runnable example application with handler implementations. ## Handler Functions @@ -73,13 +73,20 @@ To return different status codes from the same handler, use union types in your | {404, Headers3, NotFoundBody}. ``` -For complete handler examples, see `src/elli_openapi_demo.erl`. +For complete handler examples, see `example/src/elli_openapi_demo.erl`. -## Demo +## Example Application -To try out the demo application: +The `example/` directory contains a runnable demo application showcasing multiple handler implementations including user management, echo, status updates, and item updates with conflict detection. + +To run the example: ```bash -rebar3 compile +cd example rebar3 shell ``` + +The demo starts on port 3000.
