The application runs a single page web UI for demonstrating SQL for Documents (N1QL), Sub-document requests and Full Text Search (FTS) querying capabilities. It uses Couchbase Server together with the [Express] web framework for [Node.js], [Swagger] for API documentation, [Vue] and [Bootstrap]. The application is a flight planner that allows the user to search for and select a flight route (including the return flight) based on airports and dates. Airport selection is done dynamically using an autocomplete box bound to N1QL queries on the server side. After selecting a date, it then searches for applicable air flight routes from a previously populated database. An additional page allows users to search for Hotels using less structured keywords. ![Application](app.png) ## Prerequisites To download the application you can either download [the archive](https://github.com/couchbaselabs/try-cb-nodejs/archive/master.zip) or clone the repository: git clone https://github.com/couchbaselabs/try-cb-nodejs.git We recommend running the application with Docker, which starts up all components for you, but you can also run it in a Mix-and-Match style, which we'll decribe below. ## Running the application with Docker You will need [Docker](https://docs.docker.com/get-docker/) installed on your machine in order to run this application as we have defined a [_Dockerfile_](Dockerfile) and a [_docker-compose.yml_](docker-compose.yml) to run Couchbase Server 7.0.0, the front-end [Vue app](https://github.com/couchbaselabs/try-cb-frontend-v2.git) and the Node.js REST API. To launch the full application, simply run this command from a terminal: docker-compose up > **_NOTE:_** You may need more than the default RAM to run the images. We have tested the travel-sample apps with 4.5 GB RAM configured in Docker's Preferences... -> Resources -> Memory. When you run the application for the first time, it will pull/build the relevant docker images, so it may take a bit of time. This will start the Node.js backend, Couchbase Server 7.0.0 and the Vue frontend app. You can access the backend API on http://localhost:8080/, the UI on http://localhost:8081/ and Couchbase Server at http://localhost:8091/ ❯ docker-compose up Docker Compose is now in the Docker CLI, try `docker compose up` Creating network "try-cb-nodejs_default" with the default driver Pulling db (couchbase/server-sandbox:7.0.0)... ...

You should then be able to browse the UI, search for US airports and get flight route information. To end the application press Control+C in the terminal and wait for docker-compose to gracefully stop your containers. ## Mix and match services Instead of running all services, you can start any combination of `backend`, `frontend`, `db` via docker, and take responsibility for starting the other services yourself. As the provided `docker-compose.yml` sets up dependencies between the services, to make startup as smooth and automatic as possible, we also provide an alternative `mix-and-match.yml`. We'll look at a few useful scenarios here. ### Bring your own database If you wish to run this application against your own configuration of Couchbase Server, you will need version 7.0.0 or later with the `travel-sample` bucket setup. > **_NOTE:_** if you are not using Docker to start up the API server, or the > provided wrapper `wait-for-couchbase.sh`, you will need to create a full text > search index on travel-sample bucket called 'hotels-index'. You can do this > via the following command: curl --fail -s -u : -X PUT \ http://:8094/api/index/hotels-index \ -H 'cache-control: no-cache' \ -H 'content-type: application/json' \ -d @fts-hotels-index.json With a running Couchbase Server, you can pass the database details in: CB_HOST=10.144.211.101 CB_USER=Administrator CB_PSWD=password docker-compose -f mix-and-match.yml up backend frontend The Docker image will run the same checks as usual, and also create the `hotels-index` if it does not already exist. ### Running the Node.js API application manually You may want to run the Node.js application yourself, to make rapid changes to it, and try out the features of the Couchbase API, without having to re-build the Docker image. You may still use Docker to run the Database and Frontend components if desired. Install the dependencies: npm install Note that `nodemon` is installed as a dev-dependency, so you can run the server with the benefit of automatic restarting as you make changes. You will have to point your application at the Couchbase server with the `CB_HOST` environment variable. The first time you run against a new database image, you may want to use the provided `wait-for-couchbase.sh` wrapper to ensure that all indexes are created. For example, using the Docker image provided: docker-compose -f mix-and-match.yml up db export CB_HOST=localhost ./wait-for-couchbase.sh echo "Couchbase is ready!" npx nodemon index.js If you already have an existing Couchbase server running and correctly configured, you might run: CB_HOST=10.144.211.101 CB_USER=Administrator CB_PSWD=password npx nodemon index.js Finally, if you want to see how the sample frontend Vue application works with your changes, run it with: docker-compose -f mix-and-match.yml up frontend ### Running the front-end manually To run the frontend components manually without Docker, follow the guide [here](https://github.com/couchbaselabs/try-cb-frontend-v2) ## REST API reference, and tests. All the travel-sample apps conform to the same interface, which means that they can all be used with the same database configuration and Vue.js frontend. We've integrated Swagger/OpenApi version 3 documentation which can be accessed on the backend at `http://localhost:8080/apidocs` once you have started the app. (You can also view a read-only version at https://docs.couchbase.com/python-sdk/current/hello-world/sample-application.html#) To further ensure that every app conforms to the API, we have a [test suite][try-cb-test], which you can simply run with the command: ``` docker-compose --profile test up test ``` If you are running locally though, with a view to extending or modifying the travel-sample app, you will likely want to be able to make changes to both the code and the tests in parallel. * Start the backend server locally, for example using "Running the Node.js API application manually" above. * Check out the [test suite][try-cb-test] repo in a separate working directory, and run the tests manually, as per the instructions.
