# clojure-api

3+
FIXME
4+
5+
## Getting Started
6+
7+
1. Start the application: `lein run`
8+
2. Go to [localhost:8080](http://localhost:8080/) to see: `Hello World!`
9+
3. Read your app's source code at src/clojure_api/service.clj. Explore the docs of functions
10+
that define routes and responses.
11+
4. Run your app's tests with `lein test`. Read the tests at test/clojure_api/service_test.clj.
12+
5. Learn more! See the [Links section below](#links).
13+
14+
15+
## Configuration
16+
17+
To configure logging see config/logback.xml. By default, the app logs to stdout and logs/.
18+
To learn more about configuring Logback, read its [documentation](http://logback.qos.ch/documentation.html).
19+
20+
21+
## Developing your service
22+
23+
1. Start a new REPL: `lein repl`
24+
2. Start your service in dev-mode: `(def dev-serv (run-dev))`
25+
3. Connect your editor to the running REPL session.
26+
Re-evaluated code will be seen immediately in the service.
27+
28+
### [Docker](https://www.docker.com/) container support
29+
30+
1. Configure your service to accept incoming connections (edit service.clj and add ::http/host "0.0.0.0" )
31+
2. Build an uberjar of your service: `lein uberjar`
32+
3. Build a Docker image: `sudo docker build -t clojure-api .`
33+
4. Run your Docker image: `docker run -p 8080:8080 clojure-api`
34+
35+
### [OSv](http://osv.io/) unikernel support with [Capstan](http://osv.io/capstan/)
36+
37+
1. Build and run your image: `capstan run -f "8080:8080"`
38+
39+
Once the image it built, it's cached. To delete the image and build a new one:
40+
41+
1. `capstan rmi clojure-api; capstan build`
42+
43+
## Connect IDE with running REPL
44+
45+
_IntelliJ_
46+
* Go to Run > Edit Configurations and add a Remote Clojure REPL.
47+
* Set Connection Type to nREPL.
48+
* Set Host to localhost and port to the one that appears in the output of `lein repl`.
49+
* Set Context Module to the current project.
50+
* Save and close the configuration.
51+
* Hit Run and you're ready to go.
52+
53+
Whenever you change your code, hit command-shit-P to re-evaluate it in the REPL.
