Instant workspaces
No-setup VSCode environment in your browser
Access Cardano Node
Workspaces runs inside a private network which has access to the Cardano nodes running on the same cluster. Each Cardano node in the cluster has its own local domain name that can be used to dynamically resolve its location.
Query the ledger state with DB-Sync
Workspaces offers a PostgreSQL instance running within the private network of the workspace that contains updated data from DB-Sync. It's as simple as picking your favorite PostgreSQL client library.
UNIX sockets and node-to-client protocols
Upon startup, the workspace automatically mounts the corresponding socket path of the cardano node into a fixed location within the file system.
Workspaces does the infrastructure heavy lifting for you, no need to manually set up Cabal, Nix, GHC. Enabling you to focus on building your dApp.
