npm install
npm start
You can host Topola Genealogy Viewer on your own server. There are no specific requirements for the hosting server. There is no code that is executed on the server side. The server only hosts the application files and whole application runs in the browser.
You can build Topola Genealogy Viewer from source code or take a ready-to-deploy package.
Here are the commands to build the application:
git clone https://github.com/PeWu/topola-viewer.git
cd topola-viewer
npm install
npm run build
Now, take the contents of the build/ folder and host it on your own server.
Download the following file, unpack it and upload the contents to your server: https://github.com/PeWu/topola-viewer/archive/refs/heads/gh-pages.zip
These are the exact files that are hosted on GitHub pages.
The topola-webpack tool can build a Topola Genealogy Viewer package bundled together with a GEDCOM file.
Add &handleCors=false to the URL to avoid using the CORS proxy
Add &embedded=true to the URL. This option removes the options to open a different file. It is an option that was intended to be used when Topola Genealogy Viewer is in an iframe.
One of the common ways to host a GEDCOM file which can be used in Topola Genealogy Viewer is using Google Drive. Here are the steps you can follow:
- Upload the GEDCOM file to Google Drive
- Right-click the file in Google Drive and choose "Get link"
- In the "General access" section change "Restricted" to "Anyone with the link" with "Viewer" permissions.
- Click "Copy link" to get the link to the GEDCOM file.
- Open Topola Genealogy Viewer.
- Click "Open URL"
- Paste the copied URL and click "Open"
- Once the tree opens, copy the current URL.
You can now share the copied URL with someone.
Note that the URL you just copied is not discoverable. Only people who have the link will be able to see your data. It's similar to an "Unlisted" YouTube video – you can see it only if you know the link.
