# Deno
Deno is a runtime capable of running JS code including this library. There are
a few different builds and recommended use cases as covered in this demo.
Due to ongoing stability and sync issues with the Deno registry, scripts should
use [the CDN build](https://cdn.sheetjs.com/xlsx-latest/package/xlsx.mjs):
```js
// @deno-types="https://cdn.sheetjs.com/xlsx-latest/package/types/index.d.ts"
import * as XLSX from 'https://cdn.sheetjs.com/xlsx-latest/package/xlsx.mjs';
/* load the codepage support library for extended support with older formats */
import * as cptable from 'https://cdn.sheetjs.com/xlsx-latest/package/dist/cpexcel.full.mjs';
XLSX.set_cptable(cptable);
```
## Reading and Writing Files
In general, the command-line flag `--allow-read` must be passed to enable file
reading. The flag `--allow-write` must be passed to enable file writing.
_Reading a File_
```ts
const workbook = XLSX.readFile("test.xlsx");
```
_Writing a File_
Older versions of the library did not properly detect features from Deno, so the
`buffer` export would return an array of bytes. Since `Deno.writeFileSync` does
not handle byte arrays, user code must generate a `Uint8Array` first:
```ts
XLSX.writeFile(workbook, "test.xlsb");
```
## Demos
**Complete Examples**
`sheet2csv.ts` is a complete command-line tool for generating CSV text from
workbooks. Building the application is incredibly straightforward:
```bash
$ deno compile -r --allow-read sheet2csv.ts # build the sheet2csv binary
$ ./sheet2csv test.xlsx # print the first worksheet as CSV
$ ./sheet2csv test.xlsx s5s # print worksheet "s5s" as CSV
```
The [`server` demo](../server) includes a sample Deno server for parsing uploads
and generating HTML TABLE previews.
**Module Import Scenarios**
All demos attempt to read a file and write a new file. [`doit.ts`](./doit.ts)
accepts the `XLSX` module as an argument.
- `x` imports the ESM build without the codepage library:
```ts
// @deno-types="https://cdn.sheetjs.com/xlsx-latest/package/types/index.d.ts"
import * as XLSX from 'https://cdn.sheetjs.com/xlsx-latest/package/xlsx.mjs';
```
- `mjs` imports the ESM build and the associated codepage library:
```ts
import * as XLSX from '../../xlsx.mjs';
/* recommended for reading XLS files */
import * as cptable from '../../dist/cptable.full.mjs';
XLSX.set_cptable(cptable);
```
- `node` uses the node compatibility layer:
```ts
import { createRequire } from 'https://deno.land/std/node/module.ts';
const require = createRequire(import.meta.url);
const XLSX = require('../../');
```
Deno is a runtime capable of running JS code including this library.

# Knockout
# Knockout
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 a Knockout demo! You can proceed
as you would with any other browser-friendly library.
## Array of Arrays
A common data table is often stored as an array of arrays:
```js
var aoa = [ [1,2], [3,4] ];
```
This neatly maps to a table with `data-bind="foreach: ..."`:
```html
<table data-bind="foreach: aoa">
<tr data-bind="foreach: $data">
<td><span data-bind="text: $data"></span></td>
</tr>
</table>
```
The `sheet_to_json` utility function can generate array of arrays for model use:
```js
/* starting from a `wb` workbook object, pull first worksheet */
var ws = wb.Sheets[wb.SheetNames[0]];
/* convert the worksheet to an array of arrays */
var aoa = XLSX.utils.sheet_to_json(ws, {header:1});
/* update model */
model.aoa(aoa);
```
## Demo
The easiest observable representation is an `observableArray`:
```js
var ViewModel = function() { this.aoa = ko.observableArray([[1,2],[3,4]]); };
var model = new ViewModel();
ko.applyBindings(model);
```
Unfortunately the nested `"foreach: $data"` binding is read-only. A two-way
binding is possible using the `$parent` and `$index` binding context properties:
```html
<table data-bind="foreach: aoa">
<tr data-bind="foreach: $data">
<td><input data-bind="value: $parent[$index()]" /></td>
</tr>
</table>
```
The demo shows reading worksheets into a view model and writing models to XLSX.
[The new demo](https://docs.sheetjs.com/docs/getting-started/demos/legacy#knockoutjs)
includes a live example and improved explanations.

# RequireJS
The module complies with the AMD `define` semantics, enabling use in RequireJS
out of the box.
[The new demo](https://docs.sheetjs.com/docs/getting-started/demos/bundler#requirejs)
includes a live example and improved explanations.
The require config should set `xlsx` path to the appropriate dist file:
```js
paths: {
xlsx: "xlsx.full.min"
},
```
Once that is set, app code can freely require `"xlsx"`:
```js
require(["xlsx"], function(XLSX) {
/* use XLSX here */
});
```
## Deployments
`browser.html` demonstrates a dynamic deployment, using the in-browser config:
```html
<script src="require.js"></script>
<script>
require.config({
baseUrl: ".",
name: "app",
paths: {
xlsx: "xlsx.full.min"
}
});
</script>
<script src="app.js"></script>
```
`optimizer.html` demonstrates an optimized deployment using `build.js` config:
```js
/* build config */
({
baseUrl: ".",
name: "app",
paths: {
xlsx: "xlsx.full.min"
},
out: "app-built.js"
})
```
The optimizer is invoked with:
```bash
node r.js -o build.js paths.requireLib=./require include=requireLib
```
That step creates a file `app-built.js` that can be included in a page:
```html
<!-- final bundle includes require.js, library and app code -->
<script src="app-built.js"></script>
```

# Rollup
This library has a proper ESM build that is enabled by default:
[The new demo](https://docs.sheetjs.com/docs/getting-started/demos/bundler#rollup)
includes a simple example and improved explanations.
```js
import { read, utils } from 'xlsx';
```
This sample demonstrates a bundle for browser as well as for node.
This demo uses the `import` form to expose the whole library, enabling client
code to access the library with `import XLSX from 'xlsx'`. The JS code from
the root demo was moved to a separate `app.js` script.
## Required Plugins
The `rollup-plugin-node-resolve` plugin is used:
```js
import resolve from 'rollup-plugin-node-resolve';
export default {
/* ... */
plugins: [
resolve({
module: false, // <-- this library is not an ES6 module
browser: true, // <-- suppress node-specific features
})
],
/* ... */
};
```
For the browser deployments, the output format is `'iife'`. For node, the
output format is `'cjs'`.
### Worker Scripts
Rollup can also bundle worker scripts! Instead of using `importScripts`, the
worker script should import the module:
```diff
-importScripts('dist/xlsx.full.min.js');
+import * as XLSX from 'xlsx'; // or do named imports
```
