# 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/getting-started/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)
```

# Webpack
This library is built with some dynamic logic to determine if it is invoked in a
script tag or in nodejs. Webpack does not understand those feature tests, so by
default it will do some strange things.
## Basic Usage
`webpack.app.js` demonstrates bundling an entire app script in a bundle. For
basic projects requiring the module from the npm package, it is sufficient to
suppress the node shims:
```js
/* webpack config for app.out.js */
{
/* entry point app.js */
entry: './app.js',
/* write to app.out.js */
output: { path:__dirname, filename: './app.out.js' },
/* suppress node shims */
node: {
process: false,
Buffer: false
}
}
```
## Suppressing the Node shims
The library properly guards against accidental leakage of node features in the
browser but webpack disregards those. The config should explicitly suppress:
```js
node: {
process: false,
Buffer: false
}
```
## Omitting optional dependencies
The `codepage` is needed in certain special cases, including files generated by
non-US-English versions of Excel, but may not be needed. To reduce build size,
the module can be omitted by aliasing the dependency:
```js
resolve: {
alias: { "./dist/cpexcel.js": "" }
},
```
Alternatively, bundling the `xlsx.core.min.js` script always omits dependencies.
## Bower and minified versions
Webpack may show a message like "This seems to be a pre-built javascript file"
when processing minified files (like the default Bower script). The message is
harmless. To suppress the message, set `module.noParse` in the webpack config:
```js
module: {
noParse: [
/xlsx.core.min.js/,
/xlsx.full.min.js/
]
}
```
## Other Demos
This demo also attempts to demonstrate bundling of the library as well as the
core and full distribution versions. `app.js` is the common app code (it will
not be bundled). The individual bundles merely wrap and reflect `XLSX`. The
app code uses the bundles with script tag inclusion in the main HTML files. The
worker scripts use the bundles with `importScripts` references.
| required script | HTML page | entry | worker script |
|----------------:|------------:|----------:|----------------:|
| main `xlsx` lib | `main.html` | `main.js` | `mainworker.js` |
| `xlsx.core.min` | `core.html` | `core.js` | `coreworker.js` |
| `xlsx.full.min` | `full.html` | `full.js` | `fullworker.js` |
The entry points in the demo merely require and re-export the library:
```js
/* main.js */
var XLSX = require('../../');
console.log("it works!");
module.exports = XLSX;
```
The main advantage of reflecting the library is deduplication: the library code
is only downloaded once. The basic example builds a separate worker script and
eventually ships the library twice.
### Reflecting the XLSX variable
This library will not assign to `module.exports` if it is run in the browser. To
convince webpack, the demo webpack config sets `output`:
```js
output: {
libraryTarget: 'var',
library: 'XLSX'
}
```
[The new demo](https://docs.sheetjs.com/docs/getting-started/demos/bundler#webpack)
reflects the new default behavior to use the ESM build.
