## Need to publish web maps ?
* You already **use and love QGIS** as your main GIS tool
* You need to publish **full-featured applications** to the web
* You have **no time** to set up and configure web maps in **complex admin panels** nor reinventing the wheel
## Lizmap ♥ QGIS
* The **QGIS desktop project** is your **web map configuration**: symbology, printing composers, attribute tables, editing forms, expressions, etc.
* Same approach as **QField** or **Input**: QGIS is the pivot software
* **Lizmap QGIS plugin**: configure only specific map options (scales, available tools)
* **Web admin panel** mainly for **authentication and authorization management** (users & groups)
* It is **open-source**: Mozilla Public Licence
## History
* Created in **2011** as simple QGIS project viewer
* Based on **QGIS Server** and **OGC standards**: WMS, WFS, WMTS, WPS
* Has evolved to a **full-featured** web gis application generator by integrating many great **QGIS features**: symbology, relations, printing, etc.
## How-to publish a web map application:
* Create and set up your **QGIS project** (e.g. layers and server properties)
* Use **Lizmap plugin** to configure the map options and tools (extent, scales)
* **Send** your QGIS project, lizmap configuration, data and others files **to the server**
**\o/** You've got a web map based on this QGIS project **\o/**

* **ECMAScript** 6 or 2016+
* W3C **Web Components**
* **Unidirectional** User Interface Architecture
* **Bootstrap** 4
* **Jquery** 3
* **Plugin version 4**
* Lizmap as a **QGIS Server Python Service**: config, layers properties
* QGIS Server Lizmap **Access Control**: filter data/fields based on auth
## W3C Web Components
* We would like to use **native W3C Web Components** to:
* limit the **size** of our source code
* limit the **dependancies** to "cool" frameworks (maintained for ? years)
* benefit from web browser **native performances**
* We think that:
* the dependancy to OpenLayers is already **big enough**
* **standard** technologies are **sustainables**: 10 years old HTML/CSS/JS codes still works!
