Hello,

If you look in the extracted download of 4.2 you will find a document that outlines how to host it locally:

<API extraction folder>/arcgis_js_v420_api/arcgis_js_v420_api/arcgis_js_api/javascript/downloads/install-windows/index.html

Installing the ArcGIS API for JavaScript library on Windows

The instructions below assume that you are installing the ArcGIS API for JavaScript library in the following location https://www.example.com/javascript/api/4.20/ (C:\Inetpub\wwwroot\javascript\api\4.20\) on Internet Information Services (IIS) for Windows® Server, where www.example.com is the combination of the fully qualified domain name and top level domain of your web site.

If you are using a non-Windows operating system, please see the instructions on deploying the library on Unix/Linux.

The ArcGIS API for JavaScript library can be copied in its entirety to your web server directory. After copying the files to your web server, you will need to edit some files to specify the baseUrl (www.example.com/javascript/api/4.20/) for the configuration. (C:\Inetpub\wwwroot\javascript\api\4.20\). Copy \arcgis_js_v420_api\arcgis_js_api\javascript\4.20\ and all its contents from the ArcGIS API for JavaScript download to your web server. In this example the files are copied to: C:\Inetpub\wwwroot\javascript\api\4.20\.

Requirements

The default hosting configuration for both the ArcGIS API for JavaScript library and documentation is HTTPS.

HTTPS requires your web server to use a web server certificate.

IIS will need to have the following MIME types registered.extension MIME/type Description

.ttf	application/octet-stream	True Type Fonts
.wasm	application/wasm	WebAssembly
.woff	application/font-woff	Web Open Font Format
.woff2	application/font-woff2	WOFF File Format 2.0
.wsv	application/octet-stream	Supports SceneView's stars visualization

Google: Why HTTPS Matters
Google: Secure your site with HTTPS
Ignore and use HTTP

Modify the Build (manually)

Open C:\Inetpub\wwwroot\javascript\api\4.20\init.js in a text editor and search for the text [HOSTNAME_AND_PATH_TO_JSAPI], and replace this text with www.example.com/javascript/api/4.20/init.js.

Modify the Build (script)

Note: Scripting the update might be useful in a multi-machine deployment. Otherwise, it is not necessary.

This section will modify the ArcGIS API for JavaScript library [HOSTNAME_AND_PATH_TO_JSAPI]dojo text with www.example.com/javascript/api/4.20/init.js.

Node.js must be installed on the machine running the Example Node.js script (update-library.js).
Create a file such as update-library.js in a local directory.
Copy the contents of the example Node.js script (update-library.js) into the update-library.js file.
Open a terminal window and change directory (cd) to the directory containing the update-library.js script.
Verify node --version return the currently installed version of Node.js.
Update the localHost, apiDirectory, and jsapiDownloadLocation script variables.
The apiDirectory and jsapiDownloadLocation script variables will not need modified if using the same directories described in this documentation.
Execute the update-library.js script using the command node update-library.js.
Open https://www.example.com/javascript/api/4.20/init.js in a browser of your choice.
Search for baseUrl:" and verify [HOSTNAME_AND_PATH_TO_JSAPI]dojo has been replaced with the value of localHost.

Example Node.js script

The code sample below is written in JavaScript for Node.js and will automate replacing the ArcGIS API for JavaScript library [HOSTNAME_AND_PATH_TO_JSAPI]dojo text with www.example.com/javascript/api/4.20/init.js.

Note: A script like update-library.js could be written in any scripting language that supports reading/writing files and some type of string substitution manipulation such as regular expressions.

fs.writeFileSync(jsapiInitFile, updatedInitContent, "utf-8");

Test the installation

Now you should be able to access the ArcGIS API for JavaScript library from your web server using the following URL:

<script src="https://www.example.com/javascript/api/4.20/init.js"></script>

Test your installation. You can use the following test code to validate your ArcGIS API for JavaScript library installation.

Hello sir

I downloaded the API 4.21from this link https://developers.arcgis.com/downloads/#javascript

and I can not find the [HOSTNAME_AND_PATH_TO_JSAPI] in the init.js to replace it with my host location.
