The Accessibility Exchange

The Accessibility Exchange is a two-year initiative managed by the Institute for Research and Development on Inclusion and Society (IRIS) that sets out to create an online platform which will support processes where people with disabilities have the power to make sure that policies, programs, and services by federally regulated organizations are accessible to them and respect their human rights. Current consultation processes are built on a foundation of systemic ableism—they lack accountability, follow-through, and don't honour the expertise of people with disabilities.

The Accessibility Exchange platform is co-designed and developed by the Inclusive Design Research Centre at OCAD University.

Technical Details

The platform is built as a progressive web application using the Laravel 10 framework.

Installation

For general deployment information, please see the Laravel 10.x deployment documentation.

The platform requires the following:

• PHP >= 8.2 with required extensions
• MySQL >= 5.7
• Composer >= 2.0
• Node >= 18

Optionally you may wish to install NVM to make node version management easier.

The deployment process should follow all the recommended optimization processes.

Development environments

In development environments, a deployment should be followed by running a fresh migration and the development database seeder:

php artisan migrate:fresh --seeder DevSeeder

NOTE: This will overwrite all existing database tables.

Production environments

In production environments, a deployment should be followed by running all available migrations:

php artisan migrate

Development

Local Development Using Herd

Local development uses Laravel Herd.

1. Install Herd.

2. Install Xdebug or PCOV for code coverage.

3. Fork and clone the project repository (easiest with the Github CLI):

   gh repo fork accessibility-exchange/platform --clone
   cd platform

4. Create a .env file from the included example file:

   cp .env.example .env

   Then, change the APP_ENV value to local:

   APP_ENV=local

5. Generate an encryption key for CipherSweet:

   openssl rand -hex 32

   Add it to your .env file:

   CIPHERSWEET_KEY="<your key>"

6. Install Composer and NPM dependencies:

   # install composer dependencies
   composer install
   # To use the version of npm specified in .nvmrc.
   # requires https://github.com/nvm-sh/nvm
   nvm use
   # install node dependencies
   npm ci

7. Generate an application key:

   php artisan key:generate

8. Create the testing env file

   cp .env .env.testing

   Change the APP_ENV value to local:

   APP_ENV=testing

   Change the DB_DATABASE value to tae-testing:

   DB_DATABASE=tae-test

9. Create a database for development and one for running tests:

   mysql -uroot -e "create database accessibilityexchange;"
   mysql -uroot -e "create database tae-test;"

10. Run the required database migrations:

    php artisan migrate
    php artisan migrate --env=testing

11. Download the application fonts:

    php artisan google-fonts:fetch

12. Tell Herd to serve the application:

    herd link

13. Install Mailpit so that you can access transactional email from the platform:

    brew install mailpit
    brew services start mailpit

    Then, make sure that your .env file contains the following values:

    MAIL_MAILER=smtp
    MAIL_HOST=127.0.0.1
    MAIL_PORT=1025

    You will now be able to access mail that the platform sends by visiting http://127.0.0.1:8025 or http://localhost:8025. For more information and additional configuration options, read the Mailpit documentation.

For comprehensive instructions, consult the Laravel documentation. Here's an overview of how some key tasks can be carried out using Herd:

• Composer commands may be executed by using composer <command>.
• NVM commands may be executed by using nvm <command>.
• NPM commands may be executed by using npm <command>.
• Artisan commands may be executed by using php artisan <command>.

Local development setup using docker compose:

1. Install docker according to your platform instructions found here.

2. Clone the repository:

   git clone https://github.com/accessibility-exchange/platform.git && cd platform

3. Create a .env file from the included example file:

   cp .env.local.example .env

   Then, change the APP_ENV value to local:

   APP_ENV=local

4. Generate an encryption key for CipherSweet:

   docker run --rm -it alpine apk add openssl && openssl rand -hex 32

   Add it to your .env file:

   CIPHERSWEET_KEY="<your key>"

5. Generate your database password:

   docker run --rm -it alpine apk add openssl && openssl rand -hex 32

   Add it to your .env file:

   DB_PASSWORD="<your key>"

6. Generate your redis password:

   docker run --rm -it alpine apk add openssl && openssl rand -hex 20

   Add it to your .env file:

   REDIS_PASSWORD="<your key>"

7. Generate an application key:

   docker compose -f docker-compose.local.yml run --rm --entrypoint '' platform.test php artisan key:generate --show

   Add it to your .env file:

   APP_KEY="<your key>"

8. Alter the numerical IDs that PHP will run as in the application container: Reason: your local directories will be mapped into the application container to allow your changes to be viewed in real time.

   Find your local user ID & GROUP (Linux & MacOS):

   ls -ln

   You will see output like below. In the below case user is 1000 and group id is 1001.

   total 1124
   drwxr-xr-x 18 1000 1001   4096 Mar 20 12:56 app
   -rwxr-xr-x  1 1000 1001   1686 Nov  2 12:10 artisan

   Add them to your .env file:

   WWWUSER=<your user id>
   WWWGROUP=<your group id>

9. Re-build you application container after the .env file updates:

   docker compose -f docker-compose.local.yml build platform.test

10. Start up the entire stack:

docker compose -f docker-compose.local.yml up -d

11. If you are going to be committing code changes you will want to copy the php packages from the container and install node packages.

    docker cp platform.test:/app/vendor ./vendor
    nvm use
    npm ci

For comprehensive instructions, consult the Laravel documentation. Here's an overview of how some key tasks can be carried out using your containers:

• Visit the site using the SSL proxy to make sure assets load https://localhost.
• Artisan commands may be executed by using docker exec --user www-data platform.test php artisan <command>.
• NPM commands may be executed by using docker exec --user www-data platform.test npm <command>.
• Composer commands may be executed by using docker exec --user www-data platform.test composer <command>.
• !(preferred way) If you want to enter the container to run commands as www-data user (which is best when the command will create files) then use docker exec --user www-data -it platform.test bash.
• If you want to enter the container to run commands as root user then use docker exec -it platform.test bash.

Troubleshooting

Changes are missing in the container

• Rebuild the container and relaunch with the following command docker compose -f docker-compose.local.yml build platform.test && docker compose -f docker-compose.local.yml up -d.

Cannot reach site using browser

• Check that all containers are up and running using the following command docker ps -a and check for container with the name platform.test and check the status column to see if it says Up.
• If it's not up then try to check logs to see if there is an error with the command docker compose -f docker-compose.local.yml logs -f platform.test. This should help you resolve what might be missing.

Running tests

The project uses Pest for testing. For more information about testing Laravel, read the documentation.

If you make changes to the database, you may need to run the migrations in the test database.

php artisan migrate --env=testing

Development workflow

• This project uses Conventional Commits, enforced by commitlint. All commit messages and pull request titles must follow these standards.
• The dev branch contains features that have been prototyped and gone through one or more co-design sessions.
• Feature development must take place in a fork, in a branch based on the dev branch. Feature branches must be named according to the format feat/<feature>.
• Before opening a pull request, developers should run composer format && composer analyze && php artisan test --coverage to ensure that their code is properly formatted, does not cause static analysis errors, and passes tests. Depending on the code coverage, more tests may need to be written to ensure that code coverage does not drop.
• Once a feature is ready to merge into dev, the merge must be performed using a squash commit.
• The production branch contains refined features that are considered production-ready.
• Prereleases must be tagged from the dev branch.
• Releases must be tagged from the production branch.

Working with markdown

In other Laravel applications you may see methods such as Str::markdown() and Str::inlineMarkdown() used. In general we attempt to avoid using these methods and instead favour using the provided safe_markdown() and safe_inlineMarkdown helpers. These methods will escape HTML used in a markdown string, strip unsafe links, and escape replacements. They are also tied into the localization system, and will populate their strings into the string packages, just as __() would. The safe_markdown() and safe_inlineMarkdown() methods should not be called with {!! !!} as their output will safely pass through {{ }}. This provides an additional layer of protection in cases where you may have mixed types output to the template or make a mistake.

{{ safe_markdown('**hello :location**', ['location' => '**World**']) }}
{{-- <p><strong>Hello **World**</strong></p> --}}

If you need to unescape a replacement you can use a ! at the start of the placeholder name (e.g. :!placeholder).

{{ safe_markdown('**hello :!location**', ['location' => '<em>World</em>']) }}
{{-- <p><strong>Hello <em>World</em></strong></p> --}}

There are some cases where you may still wish to use the Str markdown helpers, such as when handling admin input (e.g. resource collection information). In these special cases, make sure to call the Laravel markdown helpers with the config('markdown') argument to escape HTML and remove unsafe links.

{!! Str::markdown('<em>Hello **World**</em>', config('markdown')) !!}
{{-- <p>&lt;em&gt;Hello <strong>World</strong>&lt;/em&gt;</p> --}}

Mail notification templates

By default Laravel supports a mixture of markdown and HTML in mail notification templates. However, in this application we've modified the templates to only support HTML. This aligns the behaviour of the mail templates with that of the site's blade templates.

Supported application environments

The application environment is set by specifying the APP_ENV environment variable. See Environment Configuration docs for more information.

APP_ENV	Description
local	For local development; i.e. on a developers machine.
dev	For nightly builds build and deployed from the "dev" branch.
staging	For deploys from the "staging" branch. Used to test changes in a production like environment before going live.
production	For deploys from the "production" branch. The live production released code.

Amongst other things, the application environment can be used to prevent tasks from running or requiring confirmation before running, e.g. in production running php artisan migrate:fresh requires confirmation. It can also be used to limit output in blade templates using the @env() or @production directives (See: Environment Directives docs)
