 # Other JS Engines and Deployments
 
-There are many JS engines and deployments outside of web browsers. NodeJS is the
-most popular deployment, but there are many others for special use cases.  Some
-optimize for low overhead and others optimize for ease of embedding within other
-applications.  Since it was designed for ES3 engines, the library can be used in
-those settings!  This demo tries to demonstrate a few alternative deployments.
+[The new demo](https://docs.sheetjs.com/docs/demos/engines)
+includes more detailed instructions and more JS engines.
 
-Some engines provide no default global object.  To create a global reference:
-
-```js
-var global = (function(){ return this; }).call(null);
-```
-
-
-## Swift + JavaScriptCore
-
-iOS and OSX ship with the JavaScriptCore framework for running JS scripts from
-Swift and Objective-C.  Hybrid function invocation is tricky, but explicit data
-passing is straightforward.  The demo shows a standalone example for OSX.  For
-playgrounds, the library should be copied to shared playground data directory
-(usually `~/Documents/Shared Playground Data`):
-
-```swift
-/* This only works in a playground, see SheetJSCore.swift for standalone use */
-import JavaScriptCore;
-import PlaygroundSupport;
-
-/* build path variable for the library */
-let shared_dir = PlaygroundSupport.playgroundSharedDataDirectory;
-let lib_path = shared_dir.appendingPathComponent("xlsx.full.min.js");
-
-/* prepare JS context */
-var context: JSContext! = JSContext();
-var src = "var global = (function(){ return this; }).call(null);";
-context.evaluateScript(src);
-
-/* load library */
-var lib = try? String(contentsOf: lib_path);
-context.evaluateScript(lib);
-let XLSX: JSValue! = context.objectForKeyedSubscript("XLSX");
-
-/* to verify the library was loaded, get the version string */
-let XLSXversion: JSValue! = XLSX.objectForKeyedSubscript("version")
-var version  = XLSXversion.toString();
-```
-
-Binary strings can be passed back and forth using `String.Encoding.isoLatin1`:
-
-```swift
-/* parse sheetjs.xls */
-let file_path = shared_dir.appendingPathComponent("sheetjs.xls");
-let data: String! = try String(contentsOf: file_path, encoding: String.Encoding.isoLatin1);
-context.setObject(data, forKeyedSubscript: "payload" as (NSCopying & NSObjectProtocol));
-src = "var wb = XLSX.read(payload, {type:'binary'});";
-context.evaluateScript(src);
-
-/* write to sheetjsw.xlsx  */
-let out_path = shared_dir.appendingPathComponent("sheetjsw.xlsx");
-src = "var out = XLSX.write(wb, {type:'binary', bookType:'xlsx'})";
-context.evaluateScript(src);
-let outvalue: JSValue! = context.objectForKeyedSubscript("out");
-var out: String! = outvalue.toString();
-try? out.write(to: out_path, atomically: false, encoding: String.Encoding.isoLatin1);
-```
-
-
-## Nashorn
-
-Nashorn ships with Java 8.  It includes a command-line tool `jjs` for running JS
-scripts.  It is somewhat limited but does offer access to the full Java runtime.
-
-The `load` function in `jjs` can load the minified source directly:
-
-```js
-var global = (function(){ return this; }).call(null);
-load('xlsx.full.min.js');
-```
-
-The Java `nio` API provides the `Files.readAllBytes` method to read a file into
-a byte array.  To use in `XLSX.read`, the demo copies the bytes into a plain JS
-array and calls `XLSX.read` with type `"array"`.
-
-
-## Rhino
-
-[Rhino](http://www.mozilla.org/rhino) is an ES3+ engine written in Java.  The
-`SheetJSRhino` class and `com.sheetjs` package show a complete JAR deployment,
-including the full XLSX source.
-
-Due to code generation errors, optimization must be turned off:
-
-```java
-Context context = Context.enter();
-context.setOptimizationLevel(-1);
-```
-
-
-## ChakraCore
-
-ChakraCore is an embeddable JS engine written in C++.  The library and binary
-distributions include a command-line tool `chakra` for running JS scripts.
-
-The simplest way to interact with the engine is to pass Base64 strings. The make
-target builds a very simple payload with the data.
-
-
-## Duktape
-
-[Duktape](http://duktape.org/) is an embeddable JS engine written in C.  The
-amalgamation makes integration extremely simple!  It supports `Buffer` natively
-but should be sliced before processing:
-
-```C
-/* parse a C char array as a workbook object */
-duk_push_external_buffer(ctx);
-duk_config_buffer(ctx, -1, buf, len);
-duk_put_global_string(ctx, "buf");
-duk_eval_string_noresult("workbook = XLSX.read(buf.slice(0, buf.length), {type:'buffer'});");
-
-/* write a workbook object to a C char array */
-duk_eval_string(ctx, "XLSX.write(workbook, {type:'array', bookType:'xlsx'})");
-duk_size_t sz;
-char *buf = (char *)duk_get_buffer_data(ctx, -1, sz);
-duk_pop(ctx);
-```
-
-
-## QuickJS
-
-QuickJS is an embeddable JS engine written in C.  It provides a separate set of
-functions for interacting with the filesystem and the global object.  It can run
-the browser dist build.
-
-The `global` object is available as `std.global`.  To make it visible to the
-loader, create a reference to itself:
-
-```js
-std.global.global = std.global;
-std.loadScript("xlsx.full.min.js");
-```
-
-The filesystem interaction mirrors POSIX, including separate allocations:
-
-```js
-/* read file */
-var rh = std.open(filename, "rb"); rh.seek(0, std.SEEK_END);
-var sz = rh.tell(); rh.seek();
-var ab = new ArrayBuffer(sz); rh.read(ab, 0, sz); rh.close();
-var wb = XLSX.read(ab, {type: 'array'});
-
-/* write file */
-var ab = XLSX.write(wb, {type: 'array'});
-var wh = std.open("sheetjs.qjs.xlsx", "wb");
-wh.write(out, 0, ab.byteLength); wh.close();
-```
-
-
-## Goja
-
-Goja is a pure Go implementation of ECMAScript 5.  `[]byte` should be converted
-to a binary string in the engine:
-
-```go
-/* read file */
-data, _ := ioutil.ReadFile("sheetjs.xlsx")
-
-/* load into engine */
-vm.Set("buf", data)
-
-/* convert to binary string */
-_, _ = vm.RunString("var bstr = ''; for(var i = 0; i < buf.length; ++i) bstr += String.fromCharCode(buf[i]);")
-
-/* parse */
-wb, _ = vm.RunString("wb = XLSX.read(bstr, {type:'binary', cellNF:true});")
-```
-
-On the write side, `"base64"` strings can be decoded in Go:
-
-```go
-b64str, _ := vm.RunString("XLSX.write(wb, {type:'base64', bookType:'xlsx'})")
-buf, _ := base64.StdEncoding.DecodeString(b64str.String())
-_ = ioutil.WriteFile("sheetjs.xlsx", buf, 0644)
-```

 # AngularJS
 
-The `xlsx.core.min.js` and `xlsx.full.min.js` scripts are designed to be dropped
-into web pages with script tags:
-
-```html
-<script src="xlsx.full.min.js"></script>
-```
-
-Strictly speaking, there should be no need for an Angular demo!  You can proceed
-as you would with any other browser-friendly library.
-
-This demo uses AngularJS 1.5.0.
-
-
-## Array of Objects
-
-A common data table is often stored as an array of objects:
-
-```js
-$scope.data = [
-  { Name: "Bill Clinton", Index: 42 },
-  { Name: "GeorgeW Bush", Index: 43 },
-  { Name: "Barack Obama", Index: 44 },
-  { Name: "Donald Trump", Index: 45 }
-];
-```
-
-This neatly maps to a table with `ng-repeat`:
-
-```html
-<table id="sjs-table">
-  <tr><th>Name</th><th>Index</th></tr>
-  <tr ng-repeat="row in data">
-    <td>{{row.Name}}</td>
-    <td>{{row.Index}}</td>
-  </tr>
-</table>
-```
-
-The `$http` service can request binary data using the `"arraybuffer"` response
-type coupled with `XLSX.read` with type `"array"`:
-
-```js
-  $http({
-    method:'GET',
-    url:'https://sheetjs.com/pres.xlsx',
-    responseType:'arraybuffer'
-  }).then(function(data) {
-    var wb = XLSX.read(data.data, {type:"array"});
-    var d = XLSX.utils.sheet_to_json(wb.Sheets[wb.SheetNames[0]]);
-    $scope.data = d;
-  }, function(err) { console.log(err); });
-```
-
-The HTML table can be directly exported with `XLSX.utils.table_to_book`:
-
-```js
-var wb = XLSX.utils.table_to_book(document.getElementById('sjs-table'));
-XLSX.writeFile(wb, "export.xlsx");
-```
-
-
-## Import Directive
-
-A general import directive is fairly straightforward:
-
-- Define the `importSheetJs` directive in the app:
-
-```js
-app.directive("importSheetJs", [SheetJSImportDirective]);
-```
-
-- Add the attribute `import-sheet-js=""` to the file input element:
-
-```html
-<input type="file" import-sheet-js="" multiple="false"  />
-```
-
-- Define the directive:
-
-```js
-function SheetJSImportDirective() {
-  return {
-    scope: { opts: '=' },
-    link: function ($scope, $elm) {
-      $elm.on('change', function (changeEvent) {
-        var reader = new FileReader();
-
-        reader.onload = function (e) {
-          /* read workbook */
-          var ab = e.target.result;
-          var workbook = XLSX.read(ab);
-
-          /* DO SOMETHING WITH workbook HERE */
-        };
-
-        reader.readAsArrayBuffer(changeEvent.target.files[0]);
-      });
-    }
-  };
-}
-```
-
-
-## Export Service
-
-An export can be triggered at any point!  Depending on how data is represented,
-a workbook object can be built using the utility functions.  For example, using
-an array of objects:
-
-```js
-/* starting from this data */
-var data = [
-  { name: "Barack Obama", pres: 44 },
-  { name: "Donald Trump", pres: 45 }
-];
-
-/* generate a worksheet */
-var ws = XLSX.utils.json_to_sheet(data);
-
-/* add to workbook */
-var wb = XLSX.utils.book_new();
-XLSX.utils.book_append_sheet(wb, ws, "Presidents");
-
-/* write workbook and force a download */
-XLSX.writeFile(wb, "sheetjs.xlsx");
-```
-
-## Demo
-
-`grid.html` uses `angular-ui-grid` to display a table.  The library does not
-provide any way to modify the import button, so the demo includes a simple
-directive for a HTML File Input control.  It also includes a sample service for
-export which adds an item to the export menu.
-
-The demo `SheetJSImportDirective` follows the prescription from the README for
-File input controls using `readAsArrayBuffer`, converting to a suitable
-representation and updating the scope.
-
-`SheetJSExportService` exposes export functions for `XLSB` and `XLSX`.  Other
-file formats can be exported by changing the `bookType` variable.  It grabs
-values from the grid, builds an array of arrays, generates a workbook and forces
-a download.  By setting the `filename` and `sheetname` options in the `ui-grid`
-options, the output can be controlled.

-- $http request for XLSX file and scope update with data
-- HTML table using ng-repeat
-- XLSX table export using `XLSX.utils.table_to_book`
