    dat-store aims to solve the question of "How do I make sure my Dat is being shared".

    It can be used as a CLI to watch for changes in a folder, or to keep a Dat online based on its URL.

    Note: dat-store uses features from node 10.10.0 so please make sure your version is higher than that.

    npm install -g dat-store
    # Run a store on http://localhost:3282
    dat-store run-service
    # Add a dat to the dat-store so it's always being shared
    dat-store add hyper://0a9e202b8055721bd2bc93b3c9bbc03efdbda9cfee91f01a123fdeaadeba303e/
    # Add a folder to the dat-store to create a new archive and copy changes from your folder into it.
    dat-store add ./example
    # Start synchronizing changes in an archive to a local folder
    dat-store clone ./example hyper://example.com
    # Configure external storage provider
    dat-store set-provider https://hashbase.io/ hashbase
    dat-store login yourusername hashbase
    dat-store add hyper://0a9e202b8055721bd2bc93b3c9bbc03efdbda9cfee91f01a123fdeaadeba303e/ hashbase

    How it works:

    • Uses dat-pinning-service-client to talk to storage providers that adhere to DEP 0003
    • Can start a local storage provider with dat-store run-service
    • Runs on http://localhost:3472. Configure port with --port, configure hostname / network interface with --host.
    • Server logs can be turned off using --verbose false
    • Binds to port 3282 for interacting with the P2P network. This can be configured with the --p2p-port CLI option.
    • The service uses the Dat SDK to manage archives
    • Can work with multiple providers at the same time
    • Listens on /gateway/:key/path to serve files from your achives.


    Where is stuff stored?

    This project makes use of the env-paths module to determine the best place to store data based on the platform.

    The config file is stored using the conf module, with the name dat-store. You can override the folder it'll be stored in with the --config-location flag.

    The store service is using the data directory, also with the name dat-store. You can override the folder the data will be stored at using the --storage-location flag. You can configure whether the store keeps track of just the latest changes, or the full history with the --latest flag. By default, it will store the entire history.

    How do I deal with multiple stores?

    dat-store supports multiple remote stores using the optional provider CLI argument. Whenever you add remove or list, you can specify a provider argument to tell the CLI which store it should be talking to. Think of providers as being similar to git remotes. You can add a provider with the dat-store set-provider http://example.com/ PROVIDER_NAME_HERE command.

    You can list your currently configured providers with dat-store list-providers.

    How do I add a folder?

    Depending on where a store is located, there are different ways that it can handle folders.

    For locally running stores, you can add a folder which will create a .dat file with the key of your archive and will begin to sync changes from your folder to the archive.

    You can also use the clone command with a URL and a folder to create a .dat file with the URL of the cloned archive and begin loading changes from the archive into your folder.

    For remote stores, it's a little different. Since a remote store is running on a different computer, it doesn't have a way to access your local folder. In that case, dat-store will find the Dat URL from inside the folder and will send it out to the store like it normally would.

    These two modes of operation can be combined together. When you create a dat, add it to your local store. Then add the URL to the remote store. This way, when you make a change to the folder, the local store will update the Dat, and the remote store will get the change and spread it to the rest of the network.

    How do I secure my store?

    You can require authentication for your dat-store by specifying the --authorization-username and --authorization-password flags when you run the service.

    How do I remotely control my store from the Internet?

    By default dat-store run-service will only listen on local connections.

    If you want to remotely control your service from the Internet, specify the --expose-to-internet flag. This will make the API for adding and removing stores listen on all network interfaces.

    This flag is not needed to share or download archives over the Internet, and is only intended for advanced users. You should probably combine this with the authorization flags so that random people don't abuse your store.

    NGINX Tips

    You should also consider putting your store behind NGINX with a letsecrypt certificate so that "Man In the Middle" attacks can't steal your login credentials or dat URLs.

    If you use NGINX, make sure your /etc/nginx/sites-available/your-pinning-server.com server config file looks something like this. For example, to redirect your traffic of mydatstore subdomain to the default port 3472 for dat-store:

    server {
      server_name mydatstore.my-pinning-server.com;
      location / {
        proxy_pass http://localhost:3472;
        proxy_set_header    Host            $host;
        proxy_set_header    X-Real-IP       $remote_addr;
        proxy_set_header    X-Forwarded-for $remote_addr;
        port_in_redirect    off;
        proxy_http_version  1.1;
        proxy_set_header    Upgrade         $http_upgrade;
        proxy_set_header    Connection      "Upgrade";
        listen 80;
        listen [::]:80;
        listen [::]:443 ssl; # managed by Certbot
        listen 443 ssl; # managed by Certbot
        # ... Certbot managed cerificate stuff down here ...#

    The fastify server will take care of the rest of your serving needs for the store.

    Can I access the files in an archive over HTTP?

    Yes, you can send requests to the path /gateway/:key/path/to/file. (e.g. http://localhost:42069/gateway/94f0...whatever/index.html) Only archives that are being tracked by the store will be loadable. If you want a general purpose gateway, check out fastify-hyperdrive.

    You can use NGINX again to serve the contents of an archive as a top level website with something like the following:

    server {
      server_name blog.my-pinning-server.com;
      location / {
        proxy_pass http://localhost:3472/gateway/94f0cab7f60fcc2a711df11c85db5e0594d11e8a3efd04a06f46a3c34d03c418/;
        proxy_set_header    Host            $host;
        proxy_set_header    X-Real-IP       $remote_addr;
        proxy_set_header    X-Forwarded-for $remote_addr;
        port_in_redirect    off;
        proxy_http_version  1.1;
        proxy_set_header    Upgrade         $http_upgrade;
        proxy_set_header    Connection      "Upgrade";
        listen 80;
        listen [::]:80;
        listen [::]:443 ssl; # managed by Certbot
        listen 443 ssl; # managed by Certbot
        # ... Certbot managed cerificate stuff down here ...#

    How do I make it run in the background?

    Linux (SystemD)

    # Paste this into an interactive bash or zsh shell, or save it as a file and run it with sh.
    # This will create the service file.
    sudo cat << EOF | sudo tee /etc/systemd/system/dat-store.service > /dev/null
    Description=Dat storage provider, keeps dats alive in the background.
    # Check that dat-store is present at this location
    # If it's not, replace the path with its location
    ExecStart=$(which dat-store) run-service
    sudo chmod 644 /etc/systemd/system/dat-store.service
    sudo systemctl daemon-reload
    sudo systemctl enable dat-store
    sudo systemctl start dat-store
    sudo systemctl status dat-store

    Windows (NSSM)

    • Download NSSM
    • Run the GUI with nssm install dat-store
    • For the Path option, navigate to %USERPROFILE%\AppData\Roaming\npm and click on dat-store.bat
    • Set the arguments to run-service
    • In the Login section, have it log in as your account. This is needed so it can have write access to your folders.
    • Set the log location for STDOUT and STDERR so you can debug stuff
    • Enjoy!

    To uninstall it, run nssm remove "dat-store"
