gate.computer

Host gate.computer should be an operational Gate. It can run your code.

Live demo

Running greet function of webassembly module /ipfs/QmQtrCfTTJ5tbGef8meCvZFHaaqn5ubQr9gM9FD3KewwM8.

The server call is made anonymously.

Anonymous usage with cURL

Upload and execute:

$ curl -o hello.wasm https://gate.computer/hello.wasm
$ curl -X PUT -H "Content-Type: application/wasm" --data-binary @hello.wasm -L "https://gate.computer/gate-0/module/sha256/fd17f578cf86343301b4227b3ee094084f653bb9a0c9eb687d064275bbad407b?action=call&function=greet"
hello, world

SHA-256 hash of the uploaded module contents must be included in the URL.

Executing the same module via IPFS:

$ curl -X POST -L "https://gate.computer/gate-0/module/ipfs/QmQtrCfTTJ5tbGef8meCvZFHaaqn5ubQr9gM9FD3KewwM8?action=call&function=greet"
hello, world

Anonymous usage with browser

Execute by IPFS hash via browser:

https://gate.computer/ipfs/QmQtrCfTTJ5tbGef8meCvZFHaaqn5ubQr9gM9FD3KewwM8?function=twice

Command line client with authentication support

Install a Go compiler if needed, and build the Gate client:

$ go get -u gate.computer/cmd/gate
$ PATH=$(go env GOPATH)/bin:$PATH          # In case you haven't set it up already.

If necessary, create an Ed25519 private key using OpenSSH authentication key utility:

$ ssh-keygen -t ed25519                    # Defaults to ~/.ssh/id_ed25519.
$ ssh-keygen -t ed25519 -f filename        # If you want to use a Gate-specific key (see below).

Manage resources bound to your public key:

$ gate gate.computer launch ./hello.wasm greet
01234567-89ab-odef-0123-456789abcdef

$ gate gate.computer io 01234567-89ab-cdef-0123-456789abcdef
hello, world

$ gate gate.computer instances
01234567-89ab-odef-0123-456789abcdef HALTED with result 0

$ gate gate.computer modules
fd17f578cf86343301b4227b3ee094084f653bb9a0c9eb687d064275bbad407b

The private key location can be overridden on the command line or in a configuration file:

$ gate -o identityfile=filename gate.computer call fd17f578cf86343301b4227b3ee094084f653bb9a0c9eb687d064275bbad407b greet
hello, world

$ mkdir -p ~/.config/gate
$ echo 'identityfile = "filename"' >> ~/.config/gate/client.toml
