Using Webpack with Foxx

Because the ArangoDB JavaScript environment is largely compatible with Node.js, the starting point looks fairly similar:

Foxx extends the object with a special context property that reflects the current service context. As Webpack compiles multiple modules into a single file your code will not be able to access the real module object provided by ArangoDB.

const { context } = require("@arangodb/locals");

This object is identical to module.context and can be used as a drop-in replacement:

By default Webpack will attempt to include any dependency your code imports. This makes it easy to use third-party modules without worrying about but causes problems when importing modules provided by ArangoDB.

  // ...
  externals: [/^@arangodb(\/|$)/]
};

You can also use this to exclude other modules provided by ArangoDB, like the joi validation library:

As far as Webpack is concerned, scripts are additional entry points:

const path = require("path");
  context: path.resolve(__dirname, "src"),
  entry: {
    main: "./index.js",
    setup: "./scripts/setup.js"
  }
