Moleculer v0.14.21 Release Notes

Release Date: 2022-04-30 // 26 days ago

  • 20 commits from 2 contributors.

    👍 ESM support #1063

    This version contains an ESM-based Moleculer Runner. This Runner is able to load ESM configuration file and ESM services. It can load the CJS services, as well

    Example usage

    moleculer-runner-esm --repl services/**/*.service.mjs

    Moreover, the index.js file is wrapped into index.mjs, so you can import internal modules from the core in ESM modules. E.g.:

    import { ServiceBroker, Errors } from "moleculer";

    Please note, the hot-reload function doesn't work with this ESM Runner. The cause: https://github.com/nodejs/modules/issues/307 Node maintainers try to solve the missing features (module cache and module dependency tree) with loaders but this API is not stable yet.

    Other Changes

    • broker.stopping property is created to indicate that broker is in stopping state.

    Dependency logic changed #1077

    In mixed architecture, it's not hard to create a circular service dependency that may cause a dead-lock during the start of Moleculer nodes. The problem is that Moleculer node only sends the local service registry to remote nodes after all local services started properly. As of 0.14.20, this behavior has changed. The new logic uses a debounced registry sending method which is triggered every time a local service, that the node manages, has started().
    ⏱ Note that the new method generates more INFO packets, than early versions, during the start of the node. The number of INFO packets depends on the number of the services that the node manages. The debounce timeout, between sending INFO packets, is 1 second.
