Expose swagger-ui inside your symfony project through a route (eg. /docs), just like nelmio api docs, without the need for node.
Just add a reference to your swagger Yaml or JSON specification, and enjoy swagger-ui in all it's glory.
After installation and configuration, just start your local webserver, and navigate to /docs or /docs/my_swagger_spec.yml.
If you need symfony 2.3 - 2.6 support, use version 1.x.
Install with composer in dev environment:
$ composer require harmbandstra/swagger-ui-bundle --dev
Make sure swagger-ui assets are copied to web/bundles by adding the HarmBandstra\SwaggerUiBundle\Composer\ScriptHandler::linkAssets composer hook before the Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::installAssets hook in your composer.json.
{
  "scripts": {
    "symfony-scripts": [
        "HarmBandstra\\SwaggerUiBundle\\Composer\\ScriptHandler::linkAssets",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets"
    ],
    "post-install-cmd": ["@symfony-scripts"],
    "post-update-cmd": ["@symfony-scripts"]
}Enable bundle in app/AppKernel.php:
<?php
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        // ...
        if (in_array($this->getEnvironment(), ['dev', 'test'], true)) {
            // ...
            $bundles[] = new HarmBandstra\SwaggerUiBundle\HBSwaggerUiBundle();
        }
        // ...
    }
}Add the route where swagger-ui will be available in routing_dev.yml:
_swagger-ui:
    resource: '@HBSwaggerUiBundle/Resources/config/routing.yml'
    prefix: /docsIn your config.yml, link to the swagger spec.
Specify the directory where your swagger files reside. You can access multiple files through the endpoint like /docs/my_swagger_spec.json.
Under files you specify which files should be exposed.
The first file in the array is the default one and it will be the file the /docs endpoint will redirect to. For this file you have the option to specify an absolute path to the .json spec file ("/_swagger/swagger.json") or a URL ("https://example.com/swagger.json").
hb_swagger_ui:
  directory: "%kernel.root_dir%/../docs/"
  files:
    - "/_swagger/swagger.json"
    - "my_swagger_spec.yml"
    - "my_other_swagger_spec.json"
