+# Docker Containerization Guide
+
+## Overview
+This inventory management system has been containerized with Docker for easy deployment and scaling. The setup includes:
+- Backend PHP service with Apache
+- Frontend Vue.js service with Nginx
+- MySQL database
+- Redis cache (optional)
+- External volume mounts for uploads
+
+## Quick Start
+
+### Prerequisites
+- Docker and Docker Compose installed
+- At least 2GB RAM available
+- Sufficient disk space for uploads
+
+### 1. Environment Configuration
+Copy the example environment file and customize it:
+
+```bash
+cp .env.example .env
+```
+
+Edit the `.env` file with your specific configuration:
+
+```bash
+# Database Configuration
+DB_HOST=mysql
+DB_PORT=3306
+DB_NAME=inventory_db
+DB_USER=inventory_user
+DB_PASS=your_secure_password
+MYSQL_ROOT_PASSWORD=your_root_password
+
+# Company Information
+COMPANY_NAME=Your Company Name
+COMPANY_ADDRESS=123 Business Street
+COMPANY_CITY=Helsinki
+COMPANY_POSTAL_CODE=00100
+COMPANY_COUNTRY=Finland
+COMPANY_PHONE=+358 123 456 789
+COMPANY_EMAIL=info@yourcompany.com
+COMPANY_Y_TUNNUS=1234567-8
+
+# File Upload Configuration
+UPLOAD_MAX_SIZE=10M
+ALLOWED_FILE_TYPES=pdf,doc,docx,xls,xlsx,jpg,jpeg,png,gif
+UPLOADS_PATH=./uploads
+
+# Frontend Configuration
+VUE_APP_API_URL=http://localhost:8080
+```
+
+### 2. Build and Start Containers
+```bash
+docker-compose up -d --build
+```
+
+### 3. Access the Application
+- Frontend: http://localhost:3000
+- Backend API: http://localhost:8080
+- Database: localhost:3306 (with your configured credentials)
+
+## Configuration Details
+
+### Environment Variables
+
+#### Database Configuration
+- `DB_HOST`: Database server hostname (default: mysql)
+- `DB_PORT`: Database port (default: 3306)
+- `DB_NAME`: Database name (default: inventory_db)
+- `DB_USER`: Database username (default: inventory_user)
+- `DB_PASS`: Database password (required)
+- `MYSQL_ROOT_PASSWORD`: MySQL root password (required)
+
+#### Company Information
+- `COMPANY_NAME`: Your company name
+- `COMPANY_ADDRESS`: Company address
+- `COMPANY_CITY`: Company city
+- `COMPANY_POSTAL_CODE`: Postal code
+- `COMPANY_COUNTRY`: Country
+- `COMPANY_PHONE`: Phone number
+- `COMPANY_EMAIL`: Email address
+- `COMPANY_Y_TUNNUS`: Finnish business ID
+
+#### File Upload Configuration
+- `UPLOAD_MAX_SIZE`: Maximum file upload size (default: 10M)
+- `ALLOWED_FILE_TYPES`: Allowed file extensions
+- `UPLOADS_PATH`: External path for uploads volume mount
+
+#### Frontend Configuration
+- `VUE_APP_API_URL`: Backend API URL for frontend
+
+### Volume Mounts
+
+#### Uploads Directory
+The uploads directory is mounted as an external volume to persist file uploads across container restarts:
+
+```yaml
+volumes:
+  uploads_data:
+    driver: local
+    driver_opts:
+      type: none
+      o: bind
+      device: ${UPLOADS_PATH:-./uploads}
+```
+
+#### Database Data
+MySQL data is persisted in a Docker volume:
+
+```yaml
+volumes:
+  mysql_data:
+    driver: local
+```
+
+### Network Configuration
+All services communicate through a dedicated Docker network:
+
+```yaml
+networks:
+  inventory-network:
+    driver: bridge
+```
+
+## Production Deployment
+
+### Security Considerations
+1. Change all default passwords
+2. Use HTTPS in production (configure SSL certificates)
+3. Restrict database access to internal network only
+4. Regularly update containers and dependencies
+5. Implement proper backup strategy for database and uploads
+
+### Scaling
+The architecture supports horizontal scaling:
+- Frontend can be scaled by adding more Nginx containers behind a load balancer
+- Backend can be scaled by adding more PHP containers
+- Database can be moved to external managed service
+
+### Monitoring
+Consider adding:
+- Health checks for all services
+- Log aggregation
+- Performance monitoring
+- Backup automation
+
+## Development
+
+### Local Development
+For development, you can run services individually:
+
+```bash
+# Start only database
+docker-compose up -d mysql
+
+# Start backend with live reload
+docker-compose up -d --build backend
+
+# Start frontend with live reload
+cd frontend && npm run serve
+```
+
+### Debugging
+View logs for specific services:
+
+```bash
+# Backend logs
+docker-compose logs -f backend
+
+# Frontend logs
+docker-compose logs -f frontend
+
+# Database logs
+docker-compose logs -f mysql
+```
+
+### Database Management
+Connect to the database:
+
+```bash
+docker-compose exec mysql mysql -u inventory_user -p inventory_db
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### Database Connection Failed
+1. Check if MySQL container is running: `docker-compose ps`
+2. Verify database credentials in `.env` file
+3. Check database logs: `docker-compose logs mysql`
+
+#### Upload Directory Not Working
+1. Ensure uploads directory exists on host
+2. Check permissions: `ls -la uploads/`
+3. Verify volume mount in docker-compose.yml
+
+#### Frontend Not Loading
+1. Check if backend is accessible: `curl http://localhost:8080/api/company.php`
+2. Verify API URL configuration
+3. Check frontend logs: `docker-compose logs frontend`
+
+### Performance Optimization
+1. Enable Redis caching for frequently accessed data
+2. Configure PHP OPcache for better performance
+3. Use CDN for static assets
+4. Implement database connection pooling
+
+## Maintenance
+
+### Updates
+To update the application:
+
+```bash
+# Pull latest changes
+git pull
+
+# Rebuild and restart containers
+docker-compose down
+docker-compose up -d --build
+```
+
+### Backups
+Regular backups should include:
+1. Database dump: `docker-compose exec mysql mysqldump -u root -p inventory_db`
+2. Uploads directory: `tar -czf uploads_backup.tar.gz uploads/`
+
+### Cleanup
+Remove unused containers and images:
+
+```bash
+docker system prune -a
+docker volume prune
+```
+
+## Support
+For issues and questions, refer to the application logs or contact your system administrator.

+
+### :rocket: New Feature
+
+***ESTree*** compatibility as plugin ([#277](https://github.com/babel/babylon/pull/277)) (Daniel Tschinder)
+
+We finally introduce a new compatibility layer for ESTree. To put babylon into ESTree-compatible mode the new plugin `estree` can be enabled. In this mode the parser will output an AST that is compliant to the specs of [ESTree](https://github.com/estree/estree/)
+
+We highly recommend everyone who uses babylon outside of babel to use this plugin. This will make it much easier for users to switch between different ESTree-compatible parsers. We so far tested several projects with different parsers and exchanged their parser to babylon and in nearly all cases it worked out of the box. Some other estree-compatible parsers include `acorn`, `esprima`, `espree`, `flow-parser`, etc.
+
+To enable `estree` mode simply add the plugin in the config:
+```json
+{
+  "plugins": [ "estree" ]
+}
+```
+
+If you want to migrate your project from non-ESTree mode to ESTree, have a look at our [Readme](https://github.com/babel/babylon/#output), where all deviations are mentioned.
+
+Add a parseExpression public method ([#213](https://github.com/babel/babylon/pull/213)) (jeromew)
+
+Babylon exports a new function to parse a single expression
+
+```js
+import { parseExpression } from 'babylon';
+
+const ast = parseExpression('x || y && z', options);
+```
+
+The returned AST will only consist of the expression. The options are the same as for `parse()`
+
+Add startLine option ([#346](https://github.com/babel/babylon/pull/346)) (Raphael Mu)
+
+A new option was added to babylon allowing to change the initial linenumber for the first line which is usually `1`.
+Changing this for example to `100` will make line `1` of the input source to be marked as line `100`, line `2` as `101`, line `3` as `102`, ...
+
+Function predicate declaration ([#103](https://github.com/babel/babylon/pull/103)) (Panagiotis Vekris)
+
+Added support for function predicates which flow introduced in version 0.33.0
+
+```js
+declare function is_number(x: mixed): boolean %checks(typeof x === "number");
+```
+
+Allow imports in declare module ([#315](https://github.com/babel/babylon/pull/315)) (Daniel Tschinder)
+
+Added support for imports within module declarations which flow introduced in version 0.37.0
+
+```js
+declare module "C" {
+  import type { DT } from "D";
+  declare export type CT = { D: DT };
+}
+```
+
+### :eyeglasses: Spec Compliance
+
+Forbid semicolons after decorators in classes ([#352](https://github.com/babel/babylon/pull/352)) (Kevin Gibbons)
+
+This example now correctly throws an error when there is a semicolon after the decorator:
+
+```js
+class A {
+@a;
+foo(){}
+}
+```
+
+Keywords are not allowed as local specifier ([#307](https://github.com/babel/babylon/pull/307)) (Daniel Tschinder)
+
+Using keywords in imports is not allowed anymore:
+
+```js
+import { default } from "foo";
+import { a as debugger } from "foo";
+```
+
+Do not allow overwritting of primitive types ([#314](https://github.com/babel/babylon/pull/314)) (Daniel Tschinder)
+
+In flow it is now forbidden to overwrite the primitive types `"any"`, `"mixed"`, `"empty"`, `"bool"`, `"boolean"`, `"number"`, `"string"`, `"void"` and `"null"` with your own type declaration.
+
+Disallow import type { type a } from … ([#305](https://github.com/babel/babylon/pull/305)) (Daniel Tschinder)
+
+The following code now correctly throws an error
+
+```js
+import type { type a } from "foo";
+```
+
+Don't parse class properties without initializers when classProperties is disabled and Flow is enabled ([#300](https://github.com/babel/babylon/pull/300)) (Andrew Levine)
+
+Ensure that you enable the `classProperties` plugin in order to enable correct parsing of class properties. Prior to this version it was possible to parse them by enabling the `flow` plugin but this was not intended the behaviour.
+
+If you enable the flow plugin you can only define the type of the class properties, but not initialize them.
+
+Fix export default async function to be FunctionDeclaration ([#324](https://github.com/babel/babylon/pull/324)) (Daniel Tschinder)
+
+Parsing the following code now returns a `FunctionDeclaration` AST node instead of `FunctionExpression`.
+
+```js
+export default async function bar() {};
+```

+Add support for Flow shorthand import type ([#267](https://github.com/babel/babylon/pull/267)) (Jeff Morrison)
+
+This change implements flows new shorthand import syntax
+and where previously you had to write this code:
+
+```js
+import {someValue} from "blah";
+import type {someType} from "blah";
+import typeof {someOtherValue} from "blah";
+```

+
+flow: allow leading pipes in all positions ([#256](https://github.com/babel/babylon/pull/256)) (Vladimir Kurchatkin)

+```
+
+Throw error when exporting non-declaration ([#241](https://github.com/babel/babylon/pull/241)) (Kai Cataldo)

+```
+
+### :bug: Bug Fix

+```
+
+Fix source location for JSXEmptyExpression nodes (fixes #248) ([#249](https://github.com/babel/babylon/pull/249)) (James Long)

+```
+
+Optional names for function types and object type indexers ([#197](https://github.com/babel/babylon/pull/197)) (Gabe Levi)

+
+### :eyeglasses: Spec Compliance
+
+Add static errors for object rest (#149) ([@danez](https://github.com/danez))
+
+> https://github.com/sebmarkbage/ecmascript-rest-spread
+
+Object rest copies the *rest* of properties from the right hand side `obj` starting from the left to right.
+
+```js
+let { x, y, ...z } =  { x: 1, y: 2, z: 3 };
+// x = 1
+// y = 2
+// z = { z: 3 }
+```
+
+#### New Syntax Errors:
+
+**SyntaxError**: The rest element has to be the last element when destructuring (1:10)
+```bash
+> 1 | let { ...x, y, z } = { x: 1, y: 2, z: 3};
+    |           ^
+# Previous behavior:
+# x = { x: 1, y: 2, z: 3 }
+# y = 2
+# z = 3
+```
+
+Before, this was just a more verbose way of shallow copying `obj` since it doesn't actually do what you think.
+
+**SyntaxError**: Cannot have multiple rest elements when destructuring (1:13)
+
+```bash
+> 1 | let { x, ...y, ...z } = { x: 1, y: 2, z: 3};
+    |              ^
+# Previous behavior:
+# x = 1
+# y = { y: 2, z: 3 }
+# z = { y: 2, z: 3 }
+```
+
+Before y and z would just be the same value anyway so there is no reason to need to have both.
+
+**SyntaxError**: A trailing comma is not permitted after the rest element (1:16)
+
+```js
+let { x, y, ...z, } = obj;
+```
+
+The rationale for this is that the use case for trailing comma is that you can add something at the end without affecting the line above. Since a RestProperty always has to be the last property it doesn't make sense.

+
+```js
+// Only one default export allowed per module. (2:9)
+export default function() {};
+export { foo as default };
+
+// Only one default export allowed per module. (2:0)
+export default {};
+export default function() {};
+
+// `Foo` has already been exported. Exported identifiers must be unique. (2:0)
+export { Foo };
+export class Foo {};
+```
+
+### New Feature (Syntax)
+
+- Add support for computed class property names ([#121](https://github.com/babel/babylon/pull/121)) @motiz88
+
+```js
+// AST
+interface ClassProperty <: Node {
+  type: "ClassProperty";
+  key: Identifier;
+  value: Expression;
+  computed: boolean; // added
+}
+```
+
+```js
+// with "plugins": ["classProperties"]
+class Foo {
+  [x]
+  ['y']
+}
+
+class Bar {
+  [p]
+  [m] () {}
+}
+ ```
+
+### Bug Fix
+
+- Fix `static` property falling through in the declare class Flow AST ([#135](https://github.com/babel/babylon/pull/135)) @danharper
+
+```js
+declare class X {
+    a: number;
+    static b: number; // static
+    c: number; // this was being marked as static in the AST as well
+}
+```
+
+### Polish
+
+- Rephrase "assigning/binding to rvalue" errors to include context ([#119](https://github.com/babel/babylon/pull/119)) @motiz88
+
+```js
+// Used to error with:
+// SyntaxError: Assigning to rvalue (1:0)
+
+// Now:
+// Invalid left-hand side in assignment expression (1:0)
+3 = 4
+
+// Invalid left-hand side in for-in statement (1:5)
+for (+i in {});
+```
+
+### Internal
+
+- Fix call to `this.parseMaybeAssign` with correct arguments ([#133](https://github.com/babel/babylon/pull/133)) @danez
+- Add semver note to changelog ([#131](https://github.com/babel/babylon/pull/131)) @hzoo
+
+## 6.10.0 (2016-09-19)
+
+> We plan to include some spec compliance bugs in patch versions. An example was the multiple default exports issue.
+
+### Spec Compliance
+
+* Implement ES2016 check for simple parameter list in strict mode ([#106](https://github.com/babel/babylon/pull/106)) (Timothy Gu)
+
+> It is a Syntax Error if ContainsUseStrict of FunctionBody is true and IsSimpleParameterList of FormalParameters is false. https://tc39.github.io/ecma262/2016/#sec-function-definitions-static-semantics-early-errors
+
+More Context: [tc39-notes](https://github.com/rwaldron/tc39-notes/blob/master/es7/2015-07/july-29.md#611-the-scope-of-use-strict-with-respect-to-destructuring-in-parameter-lists)
+
+For example:
+
+```js
+// this errors because it uses destructuring and default parameters
+// in a function with a "use strict" directive
+function a([ option1, option2 ] = []) {
+  "use strict";
+}
+ ```
+
+The solution would be to use a top level "use strict" or to remove the destructuring or default parameters when using a function + "use strict" or to.
+
+### New Feature
+
+* Exact object type annotations for Flow plugin ([#104](https://github.com/babel/babylon/pull/104)) (Basil Hosmer)
+
+Added to flow in https://github.com/facebook/flow/commit/c710c40aa2a115435098d6c0dfeaadb023cd39b8
+
+Looks like:
+
+```js
+var a : {| x: number, y: string |} = { x: 0, y: 'foo' };
+```
+
+### Bug Fixes
+
+* Include `typeParameter` location in `ArrowFunctionExpression` ([#126](https://github.com/babel/babylon/pull/126)) (Daniel Tschinder)
+* Error on invalid flow type annotation with default assignment ([#122](https://github.com/babel/babylon/pull/122)) (Dan Harper)
+* Fix Flow return types on arrow functions ([#124](https://github.com/babel/babylon/pull/124)) (Dan Harper)
+
+### Misc
+
+* Add tests for export extensions ([#127](https://github.com/babel/babylon/pull/127)) (Daniel Tschinder)
+* Fix Contributing guidelines [skip ci] (Daniel Tschinder)
+
+## 6.9.2 (2016-09-09)
+
+The only change is to remove the `babel-runtime` dependency by compiling with Babel's ES2015 loose mode. So using babylon standalone should be smaller.
+
+## 6.9.1 (2016-08-23)
+
+This release contains mainly small bugfixes but also updates babylons default mode to es2017. The features for `exponentiationOperator`, `asyncFunctions` and `trailingFunctionCommas` which previously needed to be activated via plugin are now enabled by default and the plugins are now no-ops.

+
+### Spec Compliance
+- The param list for type parameter declarations now consists of `TypeParameter` nodes
+- New `TypeParameter` AST Node (replaces using the `Identifier` node before)

+
+## 6.8.0 (2016-05-02)
+
+#### New Feature
+
+##### Parse Method Parameter Decorators ([#12](https://github.com/babel/babylon/pull/12))
+
+> [Method Parameter Decorators](https://goo.gl/8MmCMG) is now a TC39 [stage 0 proposal](https://github.com/tc39/ecma262/blob/master/stage0.md).
+
+Examples:
+
+```js
+class Foo {
+  constructor(@foo() x, @bar({ a: 123 }) @baz() y) {}
+}
+
+export default function func(@foo() x, @bar({ a: 123 }) @baz() y) {}
+
+var obj = {
+  method(@foo() x, @bar({ a: 123 }) @baz() y) {}
+};
+```
+
+##### Parse for-await statements (w/ `asyncGenerators` plugin) ([#17](https://github.com/babel/babylon/pull/17))
+
+There is also a new node type, `ForAwaitStatement`.
+
+> [Async generators and for-await](https://github.com/tc39/proposal-async-iteration) are now a [stage 2 proposal](https://github.com/tc39/ecma262#current-proposals).
+
+Example:
+
+```js
+async function f() {
+  for await (let x of y);
+}
+```
