This repo contains a JavaScript implementation of the Colonies API, making it possible to implement Colonies executors and applications in Javascript.
Below is some example code how to turn on/off lamp on a web page using Colonies.
let colonyId = "4787a5071856a4acf702b2ffcea422e3237a679c681314113d86139461290cf4"
let executorId = "3fc05cf3df4b494e95d6a3d297a34f19938f7daa7422ab0d4f794454133341ac"
let executorPrvKey = "ddf7f7791208083b6a9ed975a72684f6406a269cfa36f1b1c32045c0a71fff05"
let colonies = new Colonies("localhost", "50080")
function assign() {
colonies.assignLatest(colonyId, executorPrvKey)
.then((process) => {
if (process.spec.funcname == "setLampState") {
if (process.spec.args[0] == "on") {
$("#lamp").attr("src","./lamp_on.png");
}
if (process.spec.args[0] == "off") {
$("#lamp").attr("src","./lamp_off.png");
}
colonies.close(process.processid, executorPrvKey)
}
})
.catch((err) => {
console.log(err)
})
}
function subscribe() {
colonies.subscribeProcesses("cli", 30, 0, executorPrvKey, (process) => { // re-subscribe every 30 seconds
assign()
})
.catch(() => {
setTimeout(() => {
assign()
subscribe()
},2000);
})
}
colonies.load().then(() => {
assign()
subscribe()
})Note: the following environmental variables needs to be set, type source devenv.
git clone git@github.com:colonyos/colonies.git
source devenv
./bin/colonies devIn another terminal.
git clone git@github.com:colonyos/colonies.git
