Students API version openapi node

API to get student data.. API definition is contained in the OpenAPI specification.

Getting Started


  1. Install Node.js from

  2. Generate a self signed certificate with OpenSSL:

    $ openssl req -newkey rsa:2048 -new -nodes -keyout key.pem -out csr.pem
    $ openssl x509 -req -days 365 -in csr.pem -signkey key.pem -out server.crt
  3. Document API design in openapi.yaml. Please keep in mind that openapi documentation is mainly for the client's view. Directly implement the feature in the API if there is any difference between what the client should expect and what our server should provide.

  4. Copy config/default-example.yaml to config/default.yaml. Modify as necessary, being careful to avoid committing sensitive data. If you want to configure application through custom environment variables, copy config/custom-environment-variables-example.yaml as config/custom-environment-variables.yaml and map the environment variable names into your configuration structure.

    Environment variables: Sensitive data and data that changes per environment have been moved into environment variables. Below is a list of the variables along with a definition:

    Environment variable Description
    ${API_HOSTNAME} API hostname.
    ${API_PORT} The port used by the API.
    ${API_ADMIN_PORT} The port used by the ADMIN endpoint.
    ${API_USER} The HTTP Basic username used to authenticate API calls.
    ${API_PASSWD} The HTTP Basic password used to authenticate API calls.

    Options for logger configuration:

    Option Description
    size Maximum size of the file after which it will rotate. This can be a number of bytes, or units of kb, mb, and gb. If using the units, add 'k', 'm', or 'g' as the suffix. The units need to directly follow the number.
    path The directory name to save log files to.
    pattern A string representing the moment.js date format to be used for rotating. The meta characters used in this string will dictate the frequency of the file rotation. For example, if your datePattern is simply 'HH' you will end up with 24 log files that are picked up and appended to every day.
    archive A boolean to define whether or not to gzip archived log files.


# Using yarn (recommended)
$ yarn

# Using npm
$ npm install


Run the application:

# Run linting and testing tasks before starting the app
$ gulp run

# Run the app without running linting and testing tasks (only for development)
$ gulp start

Running the tests


Run ESLint to check the code:

# Using gulp
$ gulp lint

# Using npm
$ npm run lint

Note: We are following Airbnb's style as the JavaScript style guide.


Run unit tests:

# Using gulp
$ gulp test

# Using npm
$ npm test

Base project off the skeleton

Base an existing project off / Incorporate updates from the skeleton

  1. Add the skeleton as a remote:

    $ git remote add skeleton
  2. Fetch updates from the skeleton:

    $ git fetch skeleton
  3. Merge the skeleton into your codebase:

    $ git checkout feature/CO-1234-branch
    $ git merge skeleton/master
    $ git commit -v

Getting data source from the Oracle Database

The following instructions show you how to connect the API to an Oracle database.

  1. Install Oracle Instant Client by following this installation guide.

  2. Install oracledb via package management:

    # Using yarn (recommended)
    $ yarn add oracledb
    # Using npm
    $ npm install oracledb
  3. Define dataSources/oracledb section in the /config/default.yaml to be like:

      dataSources: ['oracledb']
        connectString: 'DB_URL'
        user: 'DB_USER'
        password: 'DB_PASSWD'
        poolMin: 4
        poolMax: 4
        poolIncrement: 0:

    Options for database configuration:

    Option Description
    poolMin The minimum number of connections a connection pool maintains, even when there is no activity to the target database.
    poolMax The maximum number of connections that can be open in the connection pool.
    poolIncrement The number of connections that are opened whenever a connection request exceeds the number of currently open connections.

    Note: To avoid ORA-02396: exceeded maximum idle time and prevent deadlocks, the best practice is to keep poolMin the same as poolMax. Also, ensure increasing the number of worker threads available to node-oracledb. The thread pool size should be at least equal to the maximum number of connections and less than 128.

  4. If the SQL codes/queries contain intellectual property like Banner table names, put them into api/v1/db/oracledb/contrib folder and use git-submodule to manage submodules:

    • Add the given repository as a submodule at api/v1/db/oracledb/contrib:

      $ git submodule add <contrib_repo_git_url> api/v1/db/oracledb/contrib
    • Fetch the submodule from the contrib repository:

      $ git submodule update --init
  5. Copy api/v1/db/oracledb/pets-dao-example.js to api/v1/db/oracledb/<resources>-dao.js and modify as necessary:

    $ cp api/v1/db/oracledb/pets-dao-example.js api/v1/db/oracledb/<resources>-dao.js
  6. Make sure to require the correct path for the new DAO file at path handlers files:

    const petsDao = require('../db/oracledb/<resources>-dao');


Dockerfile is also provided. To run the app in a container, install Docker first, then:

  1. Modify WORKDIR from the Dockerfile:

    # Copy folder to workspace
    WORKDIR /usr/src/students-api
    COPY . /usr/src/students-api
  2. If the API requires node-oracledb to connect to an Oracle database, download an Oracle Instant Client 12.2 Basic Light zip (64 bits) and place into ./bin folder. In addition, uncomment the following code from the Dockerfile:

    # Install Oracle Instant Client
    RUN apt-get update && apt-get install -y libaio1 unzip
    RUN mkdir -p /opt/oracle
    RUN unzip bin/ -d /opt/oracle
    RUN cd /opt/oracle/instantclient_12_2 \
        && ln -s \
        && ln -s
    RUN echo /opt/oracle/instantclient_12_2 > /etc/ \
        && ldconfig
  3. Build the docker image:

    $ docker build -t students-api .
  4. Run the app in a container:

    $ docker run -d \
                 -p 8080:8080 \
                 -p 8081:8081 \
                 -v path/to/keytools/:/usr/src/students-api/keytools:ro \
                 -v "$PWD"/config:/usr/src/students-api/config:ro \
                 -v "$PWD"/logs:/usr/src/students-api/logs \
                 --name students-api \
You can’t perform that action at this time.
