Development and deployment
|
|
==========================
|
|
|
|
There are various scripts to help setup MapComplete for deployment and develop-deployment.
|
|
|
|
This documents attempts to shed some light on these scripts.
|
|
|
|
Note: these scripts change every now and then - if the documentation here is incorrect or you run into troubles, do leave a message in [the issue tracker](https://github.com/pietervdvn/MapComplete/issues)
|

|
Architecture overview
|
|
---------------------
|
|
|
|
At its core, MapComplete is a static (!) website. There are no servers to host.
|
|
|
|
The data is fetched from Overpass/OSM/Wikidata/Wikipedia/Mapillary/... and written there directly. This means that any static file server will do to create a self-hosted version of MapComplete.
|
|
|
|
Development
|
|
-----------
|
|
|
|
To develop and build MapComplete, yo
|
|
|
|
0. Make sure you have a recent version of nodejs - at least 12.0, preferably 15
|
|
0. Make a fork and clone the repository.
|
|
1. Install `npm`. Linux: `sudo apt install npm` (or your favourite package manager), Windows: install nodeJS: https://nodejs.org/en/download/
|
|
2. Run `npm install` to install the package dependencies
|
|
3. Run `npm run init` and generate some additional dependencies and generated files
|
|
4. Run `npm run start` to host a local testversion at http://localhost:1234/index.html
|
|
5. By default, a landing page with available themes is served. In order to load a single theme, use `layout=themename` or `userlayout=true#<layout configuration>` as [Query parameter](URL_Parameters.md). Note that the shorter URLs (e.g. `bookcases.html`, `aed.html`, ...) _don't_ exist on the development version.
|
|
|
|
|
|
Deploying a fork
|
|
----------------
|
|
|
|
A script creates a webpage for every theme automatically, with some customizations in order to:
|
|
|
|
- to have shorter urls
|
|
- have individual social images
|
|
- have individual web manifests
|
|
|
|
|
|
This script can be invoked with `npm run prepare-deploy`
|
|
|
|
If you want to deploy your fork:
|
|
|
|
0. `npm run prepare-deploy`
|
|
1. `npm run build`
|
|
2. Copy the entire `dist` folder to where you host your website. Visiting `index.html` gives you the landing page, visiting `yourwebsite/<theme>` should bring you to the appropriate theme.

Weird errors
|
|
------------
|
|
|
|
Try removing `node_modules`, `package-lock.json` and `.cache`
