CFunctions
CFunctions (cloud functions, compute functions, construct functions) are a building block of the [constructs programming model] which can be used to package JavaScript code and run it on a cloud system.
Let's take a look at a simple CFunction:
const { CFunction } = require('cfunctions');
const cfunc = new CFunction({
capture: [ 'x', 'y' ],
code: 'x + y'
});
console.log('outfile:', cfunc.outfile);
console.log('env:', cfunc.env);
The output will look like this:
outfile: /tmp/.cf.out.TAJEO8/cf.js
env: { __CF__x__: '100', __CF__y__: '200' }
The cf.js file is a a self-contained JavaScript module which can be loaded
through a require() statement and returns an async function that executes the
code after binding it from a set of environment variables.
Let's execute our cfunction:
$ export __CF__x__=123
$ export __CF__y__=10
$ node -e "require('/tmp/.cf.out.TAJEO8/cf.js')().then(result => console.log(result))"
12310
The CFunction.exec() static method can also be used to execute the function:
const result = CFunction.exec('/tmp/.cf.out.TAJEO8/cf.js', {
env: {
__CF__x__: 123,
__CF__y__: 10
}
});
console.log(result);
