eventcatalog.config.js

Overview

eventcatalog.config.js contains configurations for your site and is placed in the root directory of your site.

Required fields

`cId`

Type: string

An automated generated ID for your catalog. EventCatalog will generate this for you.

eventcatalog.config.js
module.exports = {
  cId: '107fdebb-7c68-42cc-975d-413b1d30d758',
};

`title`

Type: string

Title for your website.

eventcatalog.config.js
module.exports = {
  title: 'EventCatalog',
};

`organizationName`

Type: string

Your organization name.

eventcatalog.config.js
module.exports = {
  organizationName: 'Your Company',
};

Optional fields

`base`

Type: string
Default value: /

The base path to deploy to. EventCatalog will use this path as the root for your pages and assets both in development and in production build.

eventcatalog.config.js
module.exports = {
  base: '/',
};

`output`

Added in eventcatalog@2.35.4

Type: string
Default value: static

The output type for your EventCatalog, choose from static or server.

"What is the difference between static and server?"

static - The default output type for EventCatalog. This will output a static website that you can host anywhere.
server - This will output a Node.js server that you can host anywhere. This is required for certain features like the EventCatalog Chat (bring your own keys). The easiest way to host this is with our Docker image.

eventcatalog.config.js
module.exports = {
  output: 'static',
};

`outDir`

Added in eventcatalog@2.11.4

Type: string
Default value: dist

The output path of your EventCatalog. By default it will output to the dist folder.

eventcatalog.config.js
module.exports = {
  // Catalog would output to the /build folder
  outDir: 'build',
};

`trailingSlash`

Type: boolean
Default: false

Set the route matching behavior of the dev server. Choose from the following options:

'true' - Only match URLs that include a trailing slash (ex: “/foo/“) 'false' - Match URLs regardless of whether a trailing ”/” exists

Use this configuration option if your production host has strict handling of how trailing slashes work or do not work.

eventcatalog.config.js
module.exports = {
  // Setting to true will add / onto all routes e.g http://website.com/visualiser/
  trailingSlash: true,
};

`port`

Type: number
Default: 3000

Configure the port EventCatalog is running on.

eventcatalog.config.js
module.exports = {
  // Changes the port from default 3000 to 5000
  port: 5000,
};

`host`

Added in eventcatalog@2.42.9

Type: string | boolean
Default: false

Set which network IP addresses the dev server should listen on (i.e. non-localhost IPs).

false - do not expose on a network IP address
true - listen on all addresses, including LAN and public addresses
[custom-address] - expose on a network IP address at [custom-address]

eventcatalog.config.js
module.exports = {
  host: '0.0.0.0',
};

`server.allowedHosts`

Added in eventcatalog@2.64.0

Type: string[] | true
Default: []

A list of hostnames that Astro is allowed to respond to. When the value is set to true, any hostname is allowed.

      '<rootDir>/plugin.js',
      // configuration for your generator
      {
        customValue: true,
        test: "Add any configuration values you want"
      },
    ],
  ],

      // Name of the environment
      name: 'Development',
      // URL of the environment
      url: 'https://demo.eventcatalog.dev',

`mdxOptimize`

Type: string

This is an optional configuration setting to optimize the MDX output for faster builds. This may be useful if you have many catalog files and notice slow builds. However, this option may generate some unescaped HTML, so make sure your catalog interactive parts still work correctly after enabling it.

This is disabled by default.

Read Astro documentation on optimize for MDX for more information.

eventcatalog.config.js
module.exports = {
  mdxOptimize: true
};

`compress`

Added in eventcatalog@2.48.5

Type: boolean

Setting this to true will automatically compress all your CSS, HTML, SVG, JavaScript, JSON and image files in the Astro outDir folder.

This is disabled by default from EventCatalog v2.61.9.

This only works for static builds.

eventcatalog.config.js
module.exports = {
  compress: true
};

`asyncAPI.renderParsedSchemas`

Added in eventcatalog@2.12.1

Type: boolean

EventCatalog will render your AsyncAPI files into their own pages. By default EventCatalog will read your AsyncAPI files and parse your schemas to render them on the screen. Part of this process is validating your schemas and also adding metadata onto them (default).

If you want to keep your schemas as they are then you can set the asyncAPI.renderParsedSchemas to false.

Having issues rendering AsyncAPI files?

If you are having issues seeing or rendering your AsyncAPI file try setting the renderParsedSchemas to false

  asyncAPI: {
    renderParsedSchemas: false // default is true
  }
};

};

You can choose from over 200,000 icons from icones.js.org.

    limit: 20
  }
}
