Package Exports

metavm

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (metavm) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Create script from string

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

const metavm = require('metavm');

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

// Output:
//   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.

const metavm = require('metavm');

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

// Output:
//   MetaScript {
//     name: 'Example',
//     script: Script {},
//     context: {},
//     exports: [Function]
//   }

Read script from file

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] }
//   }
