vct

VSOA Command line Tool

A command line toolbox of VSOA in JavaScript, which runs over JSRE of SylixOS, EdgerOS or Node.js for other platforms.

In addition to the client mode, this command line tool also works in server mode which support data mocking and proxy mode which is able to record all the data payloads passing through. The recorded payload could be loaded with -l option to start a replay server.

Get started

# start a mocking server
npx vct serv -j -b 'date/pub={time: new Date()}' localhost:3000 &

# start a proxy server (optionally)
npx vct proxy 

# connect the mocking server and listen (subscribe)
npx vct -l localhost:3000/date/pub

Note, installing the vct locally as devDependencies would make the command startup more quickly.
