Hide/Show Sections
show-info show/hide the documents info section
Info section contains information about the spec, such as the title and description of the spec, the version, terms of services etc. In certain situation you may not need to show this section. For instance you are embedding this element inside a another help document. Chances are, the help doc may already have this info, in that case you may want to hide this section. 		true

If you do not want your users to go through the authentication process, instead want them to use a pre-generated api-key then you may hide authentication section by setting this attribute to false and provide the api-key details using various api-key-???? attributes. true
allow-spec-url-load If set to 'false', user will not be able to load any spec url from the UI. true
allow-spec-file-load If set to 'false', user will not be able to load any spec file from the local drive. This attribute is applicable only when the device width is more than 768px, else this feature is not available true

show-curl-before-try If set to 'true', the cURL snippet is displayed between the request and the response without clicking on TRY  |  Example false
allow-server-selection If set to 'false', user will not be able to see or select API server (Server List will be hidden, however users will be able to see the server url near the 'TRY' button, to know in advance where the TRY will send the request). The URL specified in the server-url attribute will be used if set, else the first server in the API specification file will be used. true
allow-schema-description-expand-toggle Allowed: true | false allow or hide the ability to expand/collapse field descriptions in the schema true
Schema Section Settings
schema-style Allowed: tree | table - Two different ways to display object-schemas in the responses and request bodies  |  Example tree

API Server & calls
server-url OpenAPI spec has a provision for providing the server url. The UI will list all the server URLs provided in the spec. The user can then select one URL to which he or she intends to send API calls while trying out the apis. However, if you want to provide an API server of your own which is not listed in the spec, you can use this property to provide one. It is helpful in the cases where the same spec is shared between multiple environment say Dev and Test and each have their own API server. (empty)
default-api-server If you have multiple api-server listed in the spec, use this attribute to select the default API server, where all the API calls will goto. This can be changed later from the UI (empty)

When providing API key using RapiDoc element, make sure that you provide all the 3 attributes with some default values api-key-name, api-key-location & api-key-value
Set api-key-value to "-" if you are unsure of its value, and like to fill in later using JavaScript

api-key-name Name of the API key that will be send while trying out the APIs (empty)
api-key-location Allowed: header, query - determines how you want to send the api-key. (empty)
api-key-value Value of the API key that will be send while trying out the APIs. This can also be provided/overwritten from UI. (empty)
fetch-credentials Allowed: omit | same-origin | include enables passing credentials/cookies in cross domain calls, as defined in the Fetch standard, in CORS requests that are sent by the browser (empty)

                  <html>
                  ...        
                    <rapi-doc id="the-doc" spec-url = "https://.../spec.yaml"> </rapi-doc>
                    <script>
                      window.addEventListener('DOMContentLoaded', (event) => {
                        const rapidocEl = document.getElementById('the-doc');
                        rapidocEl.addEventListener('spec-loaded', (e) => {
                          rapidocEl.setApiServer(globalThis.origin + "/api");
                          // Sets the server to http://localhost:8080/api
                          // you must have defined this server in your spec
                        });
                      });
                    </script>
                  ...
                  </html>

Events

Below is an example on how to handle events using plain JS 
          
            <html>
            ...        
              <rapi-doc id="the-doc" spec-url = "https://.../spec.yaml"> </rapi-doc>

              <script>
                window.addEventListener('DOMContentLoaded', (event) => {
                  /* 
                    Ensure that the DOM is loaded, then add the event listener.
                    here we are listenig to 'before-try' event which fires when the user clicks 
                    on TRY, it then modifies the POST requests by adding a custom header 
                  */
                  const rapidocEl = document.getElementById('the-doc');
                  rapidocEl.addEventListener('before-try', (e) => {
                    if (e.detail.request.method === 'POST') {
                      e.detail.request.headers.append('custom-token', 'AAA.BBB.CCC');
                    }
                  });
                });
              </script>
            ...
            </html>
Event Description
before-render fired before rendering, provides spec object which can be modified and the changes will be reflected in rendering
spec-loaded fired after the spec is parsed, and rendered. Provides an object representing the spec.
before-try fired before user clicks try. Provides a Request like object that can be modified before making the final call to the API.
Also you get an AbortController object which can be used for aborting a request
Example: To add a custom header before making a try call 
                  
                    rapidocEl.addEventListener('before-try', (e) => {
                      if (e.detail.request.method === 'POST') {
                        e.detail.request.headers.append('my-header', 'XYX');
                      }
                    });

Example: Add a query-string param to all GET request 
                  
                    rapidocEl.addEventListener('before-try', (e) => {
                      if (e.detail.request.method === 'GET') {
                        const url = new URL( e.detail.request.url);
                        url.searchParams.append('delay', '3');
                        e.detail.request.url = url.searchParams.toString();
                      }
                    });

Example: To abort a (Try)request - Below example aborts all DELETE calls 
                  
                    rapidocEl.addEventListener('before-try', (e) => {
                      if (e.detail.request.method === 'DELETE') {
                        e.detail.controller.abort();
                      }
                    });
after-try fired after try (API-call) is completed and provides a request and response object In case of an error it will provide an request and err object
request-aborted fired when user aborts the request
api-server-change fires when you change the API server
Working Example of Event Handling In RapiDoc

Slots

slots are predefined placeholders inside a RapiDoc component. You can use these slots to place your custom html in certain desired locations inside RapiDoc. Below is an example on how to inject HTML/CSS/JS at various locations in RapiDoc 
            
              <html>
                ...
                <rapi-doc spec-url = "https://petstore.swagger.io/v2/swagger.json">
                  <div> <!-- HTML Elements without slot attribute goes into default location-->
                    <h1> My HTML Heading  </h1>
                  </div>

                  <!-- provide slot attribute to place an element at desired location -->
                  <img slot="nav-logo" src="https://via.placeholder.com/100" style="width:50px; height:50px"/>
                 
                </rapi-doc>
                ...
              </html>
Slot Name Description
(default) any content placed inside <rapi-doc> tag, will be shown immediately under the header and above the info section
logo use this slot to replace the logo on the header
header contents appear at the header after the spec-url input
footer contents appear at the bottom of the spec
nav-logo contents appear at the top of Side navigation bar usually used for logo. (only available in read-mode)
overview contents appear at overview section - top of the document. You can link to this section using #overview
servers contents appear at server section which is under the overview slot. You can link to this section using #servers
auth contents appear at authentication section which is under the overview > servers slot. You can link to this section using #auth
operations-top contents appear at the top of all the operations but below overview > servers > auth section. Use this section to provide content that applies to all the operations. You can link this section using #operations-top
tag--{tag-name} each tag is identified by a name, this slot can be used to insert HTML content under various tags
{method}-{path} each path is identified by an id. which is in the format of {method}-{path}, and certain invalid characters such as {, }, #, space is replaced by hyphen (-). Use this slot to insert HTML content into a specifi tag
Example of Slots: All Slots  |  default and footer  |  nav-logo

Advanced Styling

For those who like to perform advanced styling by building RapiDoc from source
Developers can providing their own style overrides in src/styles/custom-styles.js. This is provided as a clean way into add custom style overrides without making changes to the codebase 
                  
                    // src/styles/custom-styles.js

                    import { css } from 'lit';
                    export default css`
                      .tag.title {
                        text-transform: capitalize;
                        border-left: 2px dotted var(--red);
                      }
                    `;
and build RapiDoc 
                  
                    npm run build
generated rapidoc-min.js in dist folder will have your styles
