Bazel Watcher not Terminating Node Process (Error: Listen EADDRINUSE: address already in use :::3000)

I have a Bazel BUILD file with a nodejs_image:

package(default_visibility = ["//visibility:public"])

load("@npm_bazel_typescript//:index.bzl", "ts_library")
ts_library(
    name = "lib",
    srcs = glob(
        include = ["**/*.ts"],
        exclude = ["**/*.spec.ts"]
    ),
    deps = [
        "//packages/enums/src:lib",
        "//packages/hello/src:lib",
        "@npm//faker",
        "@npm//@types/faker",
        "@npm//express",
        "@npm//@types/express",
        "@npm//cors",
    ],
)

load("@io_bazel_rules_docker//nodejs:image.bzl", "nodejs_image")
nodejs_image(
    name = "server",
    data = [":lib"],
    entry_point = ":index.ts",
)

which boots up a simple Express Node.Js server:

app.listen(3000, () => console.log('listening on port 3000'));

When I run

ibazel run //services/server/src:server

the server starts just fine. But when I change some code and the Bazel Watcher restarts, I get this error:

Error: listen EADDRINUSE: address already in use :::3000

Hence, the previous Node.Js process wasn't killed and the port is still in use.

• Do I have to handle the termination inside my Node.Js application?

• Or is there some other method to run Node.Js code with Bazel Watcher?

• Or is it an issue with the Bazel Watcher?
