Installation

To install the frontend please do the following:

1. Make sure you have installed Git.
2. Make sure you have installed Node.js. Versions 6.0.0 and higher should work. We recommend that you use the most-recent "Active LTS" version of Node.js.
3. Make sure you have yarn installed Yarn
4. Install ember-cli latest: yarn global add ember-cli@latest. Depending on your npm permissions you might need root access to install ember-cli.
5. Clone this repo with git clone https://github.com/HospitalRun/hospitalrun-frontend, go to the cloned folder and run

yarn install

• Note: If you just want to use the project, cloning is the best option. However, if you wish to contribute to the project, you will need to fork the project first, and then clone your hospitalrun-frontend fork and make your contributions via a branch on your fork.

6. Install and configure CouchDB:
   1. Download and install CouchDB from http://couchdb.apache.org/#download.
   2. Start CouchDB:
      1. If you downloaded the installed app, navigate to CouchDB and double-click on the application.
      2. If you installed CouchDB via Homebrew or some other command line tool, launch the tool from the command line.
      3. If you're stuck with the installation, check out the instructions published here: http://docs.couchdb.org/en/1.6.1/install/index.html
   3. Verify that CouchDB is running by successfully navigating to 127.0.0.1:5984/_utils. If that fails, check the installation guide for CouchDB: http://docs.couchdb.org/en/1.6.1/install/index.html.
   4. Create admin user:
      1. If you are running CouchDB 1.x:
         1. If you have just installed CouchDB and have no admin user, please run ./script/initcouch.sh in the folder you cloned the HospitalRun repo. A user hradmin will be created with password test.
         2. If you already have a CouchDB admin user, please run ./script/initcouch.sh USER PASS in the folder you cloned the HospitalRun repo. USER and PASS are the CouchDB admin user credentials.
      2. If you are running CouchDB 2.x (experimental):
         1. HospitalRun currently does not fully support CouchDB 2.x, but you are welcome to try using it. Most functionality should work but currently creating and/or editing users does not work in CouchDB 2.x. See HospitalRun#953 for more details.
         2. If you have just installed CouchDB and have no admin user, please run ./script/initcouch2.sh in the folder you cloned the HospitalRun repo. A user hradmin will be created with password test.
         3. If you already have a CouchDB admin user, please run ./script/initcouch2.sh USER PASS in the folder you cloned the HospitalRun repo. USER and PASS are the CouchDB admin user credentials.
7. Copy the server/config-example.js to server/config.js in the folder you cloned the HospitalRun repo. If you already had a CouchDB admin user that you passed into the couch script (./script/initcouch.sh USER PASS), then you will need to modify the couchAdminUser and couchAdminPassword values in server/config.js to reflect those credentials. (Note: If on Mac, you need to make sure CouchDB can be run. See How to open an app from an unidentified developer and exempt it from Gatekeeper.)
8. Verify that CouchDB is running by visiting: http://127.0.0.1:5984/_utils/#login and logging in with the with the credentials you just created from steps 6 and 7.
   • If the page returns an error or 404:
     • Run make serve, it will start couchdb, install npm dependencies and start the server.
     • Or start the application from your applications folder.

Running the application

To start the frontend please do the following:

• Start the server by running yarn start in the repo folder. If yarn start doesn't work for you, try ember serve as an alternative.
• Go to http://localhost:4200/ in a browser and login with username hradmin and password test.

Running with Docker

Running With Docker Engine

To run HospitalRun with Docker please do the following:

• Go to https://docs.docker.com/engine/installation to download and install Docker.
• Clone the repository with the command git clone https://github.com/HospitalRun/hospitalrun-frontend.git.
• Change to the hospitalrun-frontend directory cd hospitalrun-frontend.
• Build the HospitalRun image with docker build -t hospitalrun-frontend ..
• Execute docker run -it --name couchdb -d couchdb:1.7.1 to create the couchdb container.
• Execute docker run -it --name hospitalrun-frontend -p 4200:4200 --link couchdb:couchdb -d hospitalrun-frontend to create the HospitalRun container.

Running with Docker Compose

To run HospitalRun with Docker-compose please do the following:

• Go to https://docs.docker.com/compose/install to install Docker-compose.
• Execute docker-compose up to reduce the steps to build and run the application.

Accessing HospitalRun with Docker Toolbox

If you are running with Docker Toolbox you will have to run the following commands to get the IP of the docker machine where hospitalrun-frontend is running with the following:

• Run the following command to get the ip of the docker machine that the image was created on docker-machine ip default.
• Go to http://<docker-machine ip>:4200 in a browser and login with username hradmin and password test.

Accessing HospitalRun with Docker or Docker-compose

If you are not running with Docker toolbox, please do the following:

• Go to http://localhost:4200 in a browser and login with username hradmin and password test.

Troubleshooting your local environment

Always make sure to git pull and get the latest from master.

The app will usually tell you when something needs to happen (i.e. if you try to yarn start and npm is out of date, it will tell you to run yarn update. But If you run into problems you can't resolve, feel free to open an issue, or ask for help in the HospitalRun Slack channel (you can request an invite here).

Otherwise, here are some tips for common issues:

The browser shows only a loading dialog

Is your server (still) running? Is CouchDB running? If not, that's probably the issue.

My changes aren't showing up in the browser

Try a browser refresh cmd + r.

ERR! stack python2: command not found

yarn install requires Python 2 to build some dependencies. Make sure python2 is accessible from the current working directory.

If you're using pyenv, you can run the following to override the Python version used in the current working directory:

$ pyenv install 2.7.15
$ pyenv local 2.7.15

Loading sample data

If you would like to load sample data, you can do so by navigating to Load DB under the Administration menu. You should see the following screen:

Click on Choose File and select the file sample-data.txt which is included in the root directory of the repo at sample-data.txt. Next, click on Load File. When the database load is complete a message will appear indicating if the load was successful.

Testing

Fixtures for Acceptance Tests

Fixtures are PouchDB dumps that are generated with pouchdb-dump-cli.

To create a fixture, run pouchdb-dump http://localhost:5984/main -u hradmin -p test | cat > tests/fixtures/${name_of_fixture}.txt.

To use a fixture, use runWithPouchDump(${name_of_fixture}, function(){..}); in your acceptance test. For example:

test('visiting /patients', function(assert) {
  runWithPouchDump('default', function() {
    //Actual test code here
    authenticateUser();
    visit('/patients');
    andThen(function() {
      assert.equal(currentURL(), '/patients');
    });
  });
});

Running Tests Locally

To run the test suite locally while developing, just run ember test from the project root.

Tests will also run automatically via Travis CI when you push a branch to the repository or a pull request. You can view output by going to the Travis test status from the Pull Request merge box.

Experimental

Make

If you are willing to try using make, ensure you have installed Git, Node.js and CouchDB (steps 1, 2 and 7 above), you may skip the rest. This requires CouchDB in the path to work correctly.

• Run make serve, it will start CouchDB, install npm dependencies and start the server.
• Run make all to run all tests and build the app.
• Look into Makefile to figure other targets available.

Frequently Asked Questions

Q: What is the difference between hospitalrun-frontend and hospitalrun-server?

Frontend is the primary repository and is used for development purposes. Server is the node backend, if you are looking to run HospitalRun in a clinical setting, you should use server.
