Metarhia script loader, node.js vm wrapper


Create script from string

Script contains object expression. You can use it for configs, network packets,
serialization format, etc.

``js
const metavm = require('metavm');

const src = ({ field: 'value' });;
const ms = metavm.createScript('Example', src);
console.log(ms);
`

Output:

`js
MetaScript {
name: 'Example',
script: Script {},
context: {},
exports: { field: 'value' }
}
`

Script contains function expression. You can use it for api endpoints, domain
logic stored in files or database, etc.

`js
const metavm = require('metavm');

const src = (a, b) => a + b;;
const ms = metavm.createScript('Example', src);
console.log(ms);
`

Output:

`js
MetaScript {
name: 'Example',
script: Script {},
context: {},
exports: [Function]
}
`

Read script from file

`js
const metavm = require('.');

(async () => {
const ms = await metavm.readScript('./test/examples/simple.js');
console.log(ms);
})();
`

Output:

`
MetaScript {
name: 'simple',
script: Script {},
context: {},
exports: { field: 'value', add: [Function: add], sub: [Function: sub] }
}
