Readme
The base class for confine runtimes.
npm i abstract-confine-runtime
Example usage:
const fs = require('fs')
const { AbstractConfineRuntime, APIDescription, APIObject, APIMethod, MethodNotFound } = require('abstract-confine-runtime')
module.exports = class MyConfineRuntime extends AbstractConfineRuntime {
constructor (opts) {
super(opts)
// ^ sets this.source, and this.opts
}
async init () {
// do any init that's needed prior to syscalls are restricted
// be sure to emit a 'closed' event if possible
this.myCustomProcess.on('closed', () => {
this.emit('closed', exitCode) // include unix-style exit code as first param
})
}
async run () {
// execute the script
}
async close () {
// close the script (if possible)
}
configure (opts) {
// change any options after initialization
}
describeAPI () {
// return a tree structure to describe the api, see below
return new APIDescription()
}
async handleAPICall (methodName, params) {
// handle any API calls sent to the runtime by the host environment
// if the method does not exist, throw MethodNotFound
throw new MethodNotFound()
}
}
The describeAPI()
method needs to provide a tree of APIDescription
, APIObject
, and APIMethod
objects, like so:
/* The API we want to represent: */
// hello()
// sub.method()
// zed()
return new APIDescription([
new APIMethod('hello'),
new APIObject('sub', [
new APIMethod('method')
]),
new APIMethod('zed')
])
