 # Databases
 
-"Database" is a catch-all term referring to traditional RDBMS as well as K/V
-stores, document databases, and other "NoSQL" storages. There are many external
-database systems as well as browser APIs like WebSQL and `localStorage`
+This demo has been split up for clarity:
 
-This demo discusses general strategies and provides examples for a variety of
-database systems.  The examples are merely intended to demonstrate very basic
-functionality.
+-  covers SQL and
+  structured data (including CRUD operations)
 
-
-## Structured Tables
-
-Database tables are a common import and export target for spreadsheets.  One
-common representation of a database table is an array of JS objects whose keys
-are column headers and whose values are the underlying data values. For example,
-
-| Name         | Index |
-| :----------- | ----: |
-| Barack Obama |    44 |
-| Donald Trump |    45 |
-
-is naturally represented as an array of objects
-
-```js
-[
-  { Name: "Barack Obama", Index: 44 },
-  { Name: "Donald Trump", Index: 45 }
-]
-```
-
-The `sheet_to_json` and `json_to_sheet` helper functions work with objects of
-similar shape, converting to and from worksheet objects.  The corresponding
-worksheet would include a header row for the labels:
-
-```
-XXX|      A       |   B   |
----+--------------+-------+
- 1 | Name         | Index |
- 2 | Barack Obama |    44 |
- 3 | Donald Trump |    45 |
-```
-
-
-## Building Schemas from Worksheets
-
-The `sheet_to_json` helper function generates arrays of JS objects that can be
-scanned to determine the column "types", and there are third-party connectors
-that can push arrays of JS objects to database tables.
-
-The [`sql`](http://sheetjs.com/sql) browser demo uses WebSQL, which is
-limited to the SQLite fundamental types.
-
-

-	Implementation details (click to show)
-
-The `sql` schema builder scans the first row to find headers:
-
-```js
-  if(!ws || !ws['!ref']) return;
-  var range = XLSX.utils.decode_range(ws['!ref']);
-  if(!range || !range.s || !range.e || range.s > range.e) return;
-  var R = range.s.r, C = range.s.c;
-
-  var names = new Array(range.e.c-range.s.c+1);
-  for(C = range.s.c; C<= range.e.c; ++C){
-    var addr = XLSX.utils.encode_cell({c:C,r:R});
-    names[C-range.s.c] = ws[addr] ? ws[addr].v : XLSX.utils.encode_col(C);
-  }
-```
-
-After finding the headers, a deduplication step ensures that data is not lost.
-Duplicate headers will be suffixed with `_1`, `_2`, etc.
-
-```js
-  for(var i = 0; i < names.length; ++i) if(names.indexOf(names[i]) < i)
-    for(var j = 0; j < names.length; ++j) {
-      var _name = names[i] + "_" + (j+1);
-      if(names.indexOf(_name) > -1) continue;
-      names[i] = _name;
-    }
-```
-
-A column-major walk helps determine the data type.  For SQLite the only relevant
-data types are `REAL` and `TEXT`.  If a string or date or error is seen in any
-value of a column, the column is marked as `TEXT`:
-
-```js
-  var types = new Array(range.e.c-range.s.c+1);
-  for(C = range.s.c; C<= range.e.c; ++C) {
-    var seen = {}, _type = "";
-    for(R = range.s.r+1; R<= range.e.r; ++R)
-      seen[(ws[XLSX.utils.encode_cell({c:C,r:R})]||{t:"z"}).t] = true;
-    if(seen.s || seen.str) _type = "TEXT";
-    else if(seen.n + seen.b + seen.d + seen.e > 1) _type = "TEXT";
-    else switch(true) {
-      case seen.b:
-      case seen.n: _type = "REAL"; break;
-      case seen.e: _type = "TEXT"; break;
-      case seen.d: _type = "TEXT"; break;
-    }
-    types[C-range.s.c] = _type || "TEXT";
-  }
-```
-
-

-
-The included `SheetJSSQL.js` script demonstrates SQL statement generation.
-
-
-## Objects, K/V and "Schema-less" Databases
-
-So-called "Schema-less" databases allow for arbitrary keys and values within the
-entries in the database.  K/V stores and Objects add additional restrictions.
-
-There is no natural way to translate arbitrarily shaped schemas to worksheets
-in a workbook.  One common trick is to dedicate one worksheet to holding named
-keys.  For example, considering the JS object:
-
-```json
-{
-  "title": "SheetDB",
-  "metadata": {
-    "author": "SheetJS",
-    "code": 7262
-  },
-  "data": [
-    { "Name": "Barack Obama", "Index": 44 },
-    { "Name": "Donald Trump", "Index": 45 },
-  ]
-}
-```
-
-A dedicated worksheet should store the one-off named values:
-
-```
-XXX|        A        |    B    |
----+-----------------+---------+
- 1 | Path            | Value   |
- 2 | title           | SheetDB |
- 3 | metadata.author | SheetJS |
- 4 | metadata.code   |    7262 |
-```
-
-The included `ObjUtils.js` script demonstrates object-workbook conversion:
-
-

-	Implementation details (click to show)
-
-```js
-function deepset(obj, path, value) {
-  if(path.indexOf(".") == -1) return obj[path] = value;
-  var parts = path.split(".");
-  if(!obj[parts[0]]) obj[parts[0]] = {};
-  return deepset(obj[parts[0]], parts.slice(1).join("."), value);
-}
-function workbook_to_object(wb) {
-  var out = {};
-
-  /* assign one-off keys */
-  var ws = wb.Sheets["_keys"]; if(ws) {
-    var data = XLSX.utils.sheet_to_json(ws, {raw:true});
-    data.forEach(function(r) { deepset(out, r.path, r.value); });
-  }
-
-  /* assign arrays from worksheet tables */
-  wb.SheetNames.forEach(function(n) {
-    if(n == "_keys") return;
-    out[n] = XLSX.utils.sheet_to_json(wb.Sheets[n], {raw:true});
-  });
-
-  return out;
-}
-
-function walk(obj, key, arr) {
-  if(Array.isArray(obj)) return;
-  if(typeof obj != "object") { arr.push({path:key, value:obj}); return; }
-  Object.keys(obj).forEach(function(k) { walk(obj[k], key?key+"."+k:k, arr); });
-}
-function object_to_workbook(obj) {
-  var wb = XLSX.utils.book_new();
-
-  /* keyed entries */
-  var base = []; walk(obj, "", base);
-  var ws = XLSX.utils.json_to_sheet(base, {header:["path", "value"]});
-  XLSX.utils.book_append_sheet(wb, ws, "_keys");
-
-  /* arrays */
-  Object.keys(obj).forEach(function(k) {
-    if(!Array.isArray(obj[k])) return;
-    XLSX.utils.book_append_sheet(wb, XLSX.utils.json_to_sheet(obj[k]), k);
-  });
-
-  return wb;
-}
-```

-
-## Browser APIs
-
-#### WebSQL
-
-WebSQL is a popular SQL-based in-browser database available on Chrome.  In
-practice, it is powered by SQLite, and most simple SQLite-compatible queries
-work as-is in WebSQL.
-
-The public demo  generates a database from workbook.
-
-#### LocalStorage and SessionStorage
-
-The Storage API, encompassing `localStorage` and `sessionStorage`, describes
-simple key-value stores that only support string values and keys. Objects can be
-stored as JSON using `JSON.stringify` and `JSON.parse` to set and get keys.
-
-`SheetJSStorage.js` extends the `Storage` prototype with a `load` function to
-populate the db based on an object and a `dump` function to generate a workbook
-from the data in the storage.  `LocalStorage.html` tests `localStorage`.
-
-#### IndexedDB
-
-IndexedDB is a more complex storage solution, but the `localForage` wrapper
-supplies a Promise-based interface mimicking the `Storage` API.
-
-`SheetJSForage.js` extends the `localforage` object with a `load` function to
-populate the db based on an object and a `dump` function to generate a workbook
-from the data in the storage.  `LocalForage.html` forces IndexedDB mode.
-
-
-## External Database Demos
-
-### SQL Databases
-
-There are nodejs connector libraries for all of the popular RDBMS systems.  They
-have facilities for connecting to a database, executing queries, and obtaining
-results as arrays of JS objects that can be passed to `json_to_sheet`.  The main
-differences surround API shape and supported data types.
-
-#### SQLite
-
-[The `better-sqlite3` module](https://www.npmjs.com/package/better-sqlite3)
-provides a very simple API for working with SQLite databases.  `Statement#all`
-runs a prepared statement and returns an array of JS objects.
-
-`SQLiteTest.js` generates a simple two-table SQLite database (`SheetJS1.db`),
-exports to XLSX (`sqlite.xlsx`), imports the new XLSX file to a new database
-(`SheetJS2.db`) and verifies the tables are preserved.
-
-#### MySQL / MariaDB
-
-[The `mysql2` module](https://www.npmjs.com/package/mysql2) supplies a callback
-API as well as a Promise wrapper.  `Connection#query` runs a statement and
-returns an array whose first element is an array of JS objects.
-
-`MySQLTest.js` connects to the MySQL instance running on `localhost`, builds two
-tables in the `sheetjs` database, exports to XLSX, imports the new XLSX file to
-the `sheetj5` database and verifies the tables are preserved.
-
-#### PostgreSQL
-
-[The `pg` module](https://node-postgres.com/) supplies a Promise wrapper.
-`Client#query` runs a statement and returns a result object.  The `rows` key of
-the object is an array of JS objects.
-
-`PgSQLTest.js` connects to the PostgreSQL server on `localhost`, builds two
-tables in the `sheetjs` database, exports to XLSX, imports the new XLSX file to
-the `sheetj5` database and verifies the tables are preserved.
-
-#### Knex Query Builder
-
-[The `knex` module](https://www.npmjs.com/package/knex) builds SQL queries.  The
-same exact code can be used against Oracle Database, MSSQL, and other engines.
-
-`KnexTest.js` uses the `sqlite3` connector and follows the same procedure as the
-SQLite test.  The included `SheetJSKnex.js` script converts between the query
-builder and the common spreadsheet format.
-
-### Key/Value Stores
-
-#### Redis
-
-Redis is a powerful data structure server that can store simple strings, sets,
-sorted sets, hashes and lists.  One simple database representation stores the
-strings in a special worksheet (`_strs`), the manifest in another worksheet
-(`_manifest`), and each object in its own worksheet (`obj##`).
-
-`RedisTest.js` connects to a local Redis server, populates data based on the
-official Redis tutorial, exports to XLSX, flushes the server, imports the new
-XLSX file and verifies the data round-tripped correctly.  `SheetJSRedis.js`
-includes the implementation details.
-
-#### LowDB
-
-LowDB is a small schemaless database powered by `lodash`.  `_.get` and `_.set`
-helper functions make storing metadata a breeze.  The included `SheetJSLowDB.js`
-script demonstrates a simple adapter that can load and dump data.
-
-### Document Databases
-
-Since document databases are capable of holding more complex objects, they can
-actually hold the underlying worksheet objects!  In some cases, where arrays are
-supported, they can even hold the workbook object.
-
-#### MongoDB
-
-MongoDB is a popular document-oriented database engine.  `MongoDBTest.js` uses
-MongoDB to hold a simple workbook and export to XLSX.
-
-`MongoDBCRUD.js` follows the SQL examples using an idiomatic collection
-structure.  Exporting and importing collections are straightforward:
-
-

-	Example code (click to show)
-
-```js
-/* generate a worksheet from a collection */
-const aoa = await db.collection('coll').find({}).toArray();
-aoa.forEach((x) => delete x._id);
-const ws = XLSX.utils.json_to_sheet(aoa);
-
-
-/* import data from a worksheet to a collection */
-const aoa = XLSX.utils.sheet_to_json(ws);
-await db.collection('coll').insertMany(aoa, {ordered: true});
-```
-
-

-
-#### Firebase
-
-[`firebase-server`](https://www.npmjs.com/package/firebase-server) is a simple
-mock Firebase server used in the tests, but the same code works in an external
-Firebase deployment when plugging in the database connection info.
-
-`FirebaseDemo.html` and `FirebaseTest.js` demonstrate a whole-workbook process.
-The entire workbook object is persisted, a few cells are changed, and the stored
-data is dumped and exported to XLSX.
+- https://docs.sheetjs.com/docs/getting-started/demos/nosql covers unstructured
+  data including "NoSQL" data stores.

 # canvas-datagrid
 
-The `sheet_to_json` utility function generates output arrays suitable for use
-with other JS libraries such as data grids for previewing data.  After extensive
-testing, [`canvas-datagrid`](https://canvas-datagrid.js.org/demo.html) stood
-out as a very high-performance grid with an incredibly simple API.
+[The new demo](https://docs.sheetjs.com/docs/getting-started/demos/grid#canvas-datagrid)
+includes a live example and improved explanations.
 
-This demo is available at 
-
-## Obtaining the Library
-
-The `canvas-datagrid` NodeJS packages include a minified script that can be
-directly inserted as a script tag.  The unpkg CDN also serves this script:
-
-```html
-
-```
-
-## Previewing Data
-
-The HTML document needs a container element:
-
-```html
-

-```
-
-Grid initialization is a one-liner:
-
-```js
-var grid = canvasDatagrid({
-  parentNode: document.getElementById('gridctr'),
-  data: []
-});
-```
-
-For large data sets, it's necessary to constrain the size of the grid.
-
-```js
-grid.style.height = '100%';
-grid.style.width = '100%';
-```
-
-Once the workbook is read and the worksheet is selected, assigning the data
-variable automatically updates the view:
-
-```js
-grid.data = XLSX.utils.sheet_to_json(ws, {header:1});
-```
-
-This demo previews the first worksheet.
-
-## Editing
-
-`canvas-datagrid` handles the entire edit cycle.  No intervention is necessary.
-
-## Saving Data
-
-`grid.data` is immediately readable and can be converted back to a worksheet.
-Some versions return an array-like object without the length, so a little bit of
-preparation may be needed:
-
-```js
-/* converts an array of array-like objects into an array of arrays */
-function prep(arr) {
-  var out = [];
-  for(var i = 0; i < arr.length; ++i) {
-    if(!arr[i]) continue;
-    if(Array.isArray(arr[i])) { out[i] = arr[i]; continue };
-    var o = new Array();
-    Object.keys(arr[i]).forEach(function(k) { o[+k] = arr[i][k] });
-    out[i] = o;
-  }
-  return out;
-}
-
-/* build worksheet from the grid data */
-var ws = XLSX.utils.aoa_to_sheet(prep(grid.data));
-
-/* build up workbook */
-var wb = XLSX.utils.book_new();
-XLSX.utils.book_append_sheet(wb, ws, 'SheetJS');
-
-/* generate download */
-XLSX.writeFile(wb, "SheetJS.xlsx");
-```
-
-## Additional Features
-
-This demo barely scratches the surface.  The underlying grid component includes
-many additional features including massive data streaming, sorting and styling.

 # NW.js
 
-This library is compatible with NW.js and should just work out of the box.
-The demonstration uses NW.js 0.63.0 with the dist script.
-
-## Reading data
-
-The standard HTML5 `FileReader` techniques from the browser apply to NW.js!
-This demo includes a drag-and-drop box as well as a file input box, mirroring
-the [SheetJS Data Preview Live Demo](https://oss.sheetjs.com/sheetjs/).
-
-## Writing data
-
-File input elements with the attribute `nwsaveas` show UI for saving a file. The
-standard trick is to generate a hidden file input DOM element and "click" it.
-Since NW.js does not present a `writeFileSync` in the `fs` package, a manual
-step is required:
-
-```js
-/* from within the input change callback, `this.value` is the file name */
-var filename = this.value, bookType = (filename.match(/[^\.]*$/)||["xlsx"])[0];
-
-/* convert the TABLE element back to a workbook */
-var wb = XLSX.utils.table_to_book(HTMLOUT);
-
-/* write to buffer */
-var wbout = XLSX.write(wb, {type:'buffer', bookType:bookType});
-
-/* use the async fs.writeFile to save the data */
-fs.writeFile(filename, wbout, function(err) {
-	if(!err) return alert("Saved to " + filename);
-	alert("Error: " + (err.message || err));
-});
-```
+[The new demo](https://docs.sheetjs.com/docs/getting-started/demos/desktop#nwjs)
+includes an improved example and detailed explanations.

 # TypeScript
 
-The library exports can be imported directly from TS code with:
-
-```typescript
-import * as XLSX from 'xlsx';
-```
-
-The library type definitions are available in the repo at `types/index.d.ts` and
-in the node module.  The definitions are also available in places that serve the
-node module, like [unpkg](https://unpkg.com/xlsx/types/index.d.ts).
-
-This demo shows a small utility function that reads the first worksheet and
-converts to an array of arrays.  The utility function is designed to be used in
-the browser and server.  This project shows a complete deployment as a simple
-browser script and as a node module.
-
-This demo is intended to illustrate simple and direct use of the `tsc` command
-line utility.  The Angular 2+ demo shows a more advanced TypeScript deployment.
-
-
-## Named Exports
-
-Newer TypeScript versions (2.6+) support named exports:
-
-```typescript
-import { read, write, utils } from 'xlsx'
-```
-
-However, since this is not supported in all deployments, it is generally easier
-to use the glob import form and destructuring assignment:
-
-```typescript
-import * as XLSX from 'xlsx';
-const { read, write, utils } = XLSX;
-```
-
-
-## Library Type Definitions
-
-Types are exposed in the node module directly in the path `/types/index.d.ts`.
-[unpkg CDN includes the definitions](https://unpkg.com/xlsx/types/index.d.ts).
-The named `@types/xlsx` module should not be installed!
-
-Using the glob import, types must be explicitly scoped:
-
-```typescript
-import * as XLSX from 'xlsx';
-/* the workbook type is accessible as XLSX.WorkBook */
-const wb: XLSX.WorkBook = XLSX.read(data, options);
-```
-
-Using named imports, the explicit type name should be imported:
-
-```typescript
-import { read, WorkBook } from 'xlsx'
-const wb: WorkBook = read(data, options);
-```
-
-
-## Demo Project Structure
-
-`lib/index.ts` is the TS library that will be transpiled to `dist/index.js` and
-`dist/index.d.ts`.
-
-`demo.js` is a node script that uses the generated library.
-
-`src/index.js` is the browser entry point.  The `browserify` bundle tool is used
-to generate `dist/browser.js`, a browser script loaded by `index.html`.
+This demo originally covered direct use of the `tsc` TypeScript compiler.  At
+the time when the demo was first written, TypeScript 2.2 had a module system
+that was incompatibile with the pure JS ecosystem.  Since then, various
+language improvements and compiler changes have obviated this demo.  Uses of
+TypeScript are scattered throughout other demos.
