Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
@cycle/run
Advanced tools
Cycle.js run(main, drivers)
function for applications written with xstream.
npm install @cycle/run xstream
Note: xstream
package is required too.
import {run} from '@cycle/run'
run(main, drivers)
setup(main, drivers)
A function that prepares the Cycle application to be executed. Takes a main
function and prepares to circularly connects it to the given collection of
driver functions. As an output, setup()
returns an object with three
properties: sources
, sinks
and run
. Only when run()
is called will
the application actually execute. Refer to the documentation of run()
for
more details.
Example:
import {setup} from '@cycle/run';
const {sources, sinks, run} = Cycle(main, drivers);
// ...
const dispose = run(); // Executes the application
// ...
dispose();
main: Function
a function that takes sources
as input and outputs sinks
.drivers: Object
an object where keys are driver names and values are driver functions.(Object) an object with three properties: sources
, sinks
and run
. sources
is the collection of driver sources, sinks
is the
collection of driver sinks, these can be used for debugging or testing. run
is the function that once called will execute the application.
run(main, drivers)
Takes a main
function and circularly connects it to the given collection
of driver functions.
Example:
import run from '@cycle/run';
const dispose = run(main, drivers);
// ...
dispose();
The main
function expects a collection of "source" streams (returned from
drivers) as input, and should return a collection of "sink" streams (to be
given to drivers). A "collection of streams" is a JavaScript object where
keys match the driver names registered by the drivers
object, and values
are the streams. Refer to the documentation of each driver to see more
details on what types of sources it outputs and sinks it receives.
main: Function
a function that takes sources
as input and outputs sinks
.drivers: Object
an object where keys are driver names and values are driver functions.(Function) a dispose function, used to terminate the execution of the Cycle.js program, cleaning up resources used.
