⚠️🧪 Work in progress! Currently this project is in public beta

Installation

npm install -S @qgis-js/utils

Usage

useProjects

Provides an abstraction to load QGIS projects from various sources.

import { qgis } from "qgis-js";
import { useProjects } from "@qgis-js/utils";

const { api, fs } = await qgis();
const {
  openProject,
  loadLocalProject,
  loadGithubProjects,
  loadRemoteProjects,
} = useProjects(fs, (projectPath: string) => {
  api.loadProject(projectPath);
});

The following project sources are supported:

LocalProject

Loads QGIS projects from the user's file system with the File System API

await openProject(await loadLocalProject());

GithubProject

Loads QGIS projects from a GitHub repository with the GitHub API

RemoteProject

Fetches QGIS projects from a remote server with the Fetch API

• If loadRemoteProjects is invoked with a string as, it is assumed to be the URL of a JSON file with the following structure:

{
  "name": "projects",
  "path": "projects",
  "type": "Folder",
  "entries": [
    {
      "name": "village",
      "path": "projects/village",
      "type": "Folder",
      "entries": [
        {
          "name": "project.qgs",
          "path": "projects/village/project.qgs",
          "type": "File"
        },
        {
          "name": "rgb.tif",
          "path": "projects/village/rgb.tif",
          "type": "File"
        }
      ]
    }
  ]
}

• Otherwise a Folder object can also be passed directly to loadRemoteProjects, see FileSystem.ts
