Testing

Spell Checking

We write the docs in US English and enforce this at build time with a CI check. You can run the check locally using the following command:

./node_modules/.bin/mdspell -r -n -a --en-us '_documentation/en/**/*.md' '_partials/*.md' '_partials/**/*.md' '_modals/**/*.md' '_tutorials/**/*.md'

Or if you're using Docker:

docker-compose exec web ./node_modules/.bin/mdspell -r -n -a --en-us '_documentation/en/**/*.md' '_partials/*.md' '_partials/**/*.md' '_modals/**/*.md' '_tutorials/**.md'

If there is a word that isn't in the dictionary but is correct to use, add it to the .spelling file (there's a lot of exceptions in there, including Nexmo!)

Running locally

The project can be run on your laptop, either directly or using Docker. These instructions have been tested for Mac.

Setup for running directly on your laptop

Before you start, you need to make sure that you have:

System Setup (OSX)

Install Homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install required packages, create database and configure git.

Note: A default database is created for you when you run the db:setup script. If you'd like to create and use a different database or user, use createdb database_name_here or createuser username_here and make sure your .env file is updated accordingly (See .env.example).

brew install postgres rbenv git yarn nvm redis
brew services start postgresql
brew services start redis


git config --global user.name "NAME"
git config --global user.email "user.name@vonage.com"

Generate an SSH key for authentication

ssh-keygen -t rsa
cat .ssh/id_rsa.pub # Add to GitHub

Clone NDP to your local machine

git clone git@github.com:Nexmo/nexmo-developer.git
cd nexmo-developer
cp .env.example .env

Install the correct versions of ruby

rbenv install 2.5.8
rbenv global 2.5.8
gem install bundle
bundle install

Edit the .env file as appropriate for your platform. Then, run the following:

bundle exec nexmo-developer --docs=`pwd`

You should now be able to see the site on http://localhost:3000/

Setting up with Docker

If you don't want to install Ruby & PostgreSQL then you can use docker to sandbox Nexmo Developer into its own containers. After you Install Docker run the following:

$ git clone git@github.com:Nexmo/nexmo-developer.git
$ cd nexmo-developer

$ docker-compose up

Once docker-compose up has stopped returning output, open a new terminal and run docker-compose run web bundle exec rake db:migrate.

At this point, open your browser to http://localhost:3000/ and you should see the homepage. The first time you click on Documentation it might take 5 seconds or so, but any further page loads will be almost instantaneous.

To stop the server press ctrl+c.

If you get an error that says "We're sorry, but something went wrong." you might need to run the database migrations with docker-compose run web bundle exec rake db:migrate

Admin dashboard

You can access the admin dashboard by visiting /admin. Initially, you will have an admin user with the username of api.admin@vonage.com and password of development.

The following is an example if you are running Nexmo Developer within a Docker container:

docker exec -it <container_id> rake db:seed

New admin users can be created by visiting /admin/users.

Working with submodules

Some of the contents of NDP are brought in via git submodules, such as the OpenAPI Specification (OAS) documents. A submodule is a separate repository used within the main repository (in this case NDP) as a dependency. The main repository holds information about the location of the remote repository and which commit to reference. So to make a change within a submodule, you need to commit to the submodule and the main repository and crucially remember to push both sets of changes to GitHub.

Here are some tips for working with submodules:

When cloning the repo or starting to work with submodules

git submodule init
git submodule update

When pulling in changes to a branch e.g. updating master

git pull
git submodule update

When making changes inside the submodule within NDP

Make sure you are inside the directory that is a submodule.

make your changes
commit your changes
push your changes from here (this is the bit that normally trips us up)
open a pull request on the submodule's repository - we can't open the PR on the main repo until this is merged

You are not done, keep reading! A second pull request is needed to update the main repo, including any other changes to that repo and an update to the submodule pointing to the new (merged) commit to use.

open your PR for this change including any changes to the main project (so we don't lose it) but label it "don't merge" and add the URL of the submodule PR we're waiting for
once the submodule has the change you need on its master branch, change into the subdirectory and git pull
change directory back up to the root of the project
commit the submodules changes
push these changes too
Now we can review your PR

Bringing submodule changes into NDP

If you made changes on the repo outside of NDP, then you will need to come and make a commit on NDP to update which commit in the submodule the NDP repository is pointing to.

Make a branch, change into the submodule directory and git pull or do whatever you need to do to get HEAD pointing to the correct commit. In the top level of the project, add the change to the submodules file and commit and push. Then open the pull request as you would with any other changes.

Further advice and resources for successful submodule usage

Never git add . this will make bad things happen with submodules. Try git add -p instead. You're welcome.

If you're not sure what to do, ask for help. It's easier to lend a hand along the way than to rescue it later!

Troubleshooting

I'm having issues with my Docker container

The image may have changed, try rebuilding it with the following command:

$ docker-compose up --build

I get an exception `PG::ConnectionBad - could not connect to server: Connection refused` when I try to run the app.

This error indicates that PostgreSQL is not running. If you installed PostgreSQL using brew you can get information about how to start it by running:

$ brew info postgresql

Once PostgreSQL is running you'll need to create and migrate the database. See Setup for instructions.

Upgrading Volta

Volta is the Vonage design system, and is used to style Nexmo Developer. To upgrade the version of Volta used:

Clone Volta on to your local machine
Remove the app/assets/volta/scss folder in Nexmo Developer
Copy the scss folder from the Volta repo in to app/assets/volta
Commit and push. Rails will take care of compilation etc

Contributing

We ❤️ contributions from everyone! It is a good idea to talk to us first if you plan to add any new functionality. Otherwise, bug reports, bug fixes and feedback on the library is always appreciated. Look at the Contributor Guidelines for more information and please follow the GitHub Flow.

Content Updates

Follow these instructions to make updates to any content in the Nexmo Developer repository.

Checkout a new branch, naming it appropriately:

git checkout -b your-branch-name

Locate the file containing the content you wish to update in _documentation/en and open it in your preferred editor. The URL on the documentation site translates to the file path in _documentation/en.

Make and save the necessary updates in the file.

Add your changes:

git add -p

Commit the changes in your branch. Include a commit message adequately describing the update(s):

git commit -m “Add a commit message”

Push your branch in order to raise a pull request:

git push origin your-branch-name

Create a pull request in GitHub:

In the nexmo-developer repository, click the Pull requests tab.
Click the Compare and new pull request button next to your branch in the list.
Review the changes between your branch and master.
Add a Description of the changes.
Click the Create pull request button.
