Bazel Watcher 未终止节点进程（错误：听 EADDRINUSE：地址已在使用中 :::3000）

Question

我有一个带有以下内容的 Bazel BUILD 文件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",
)

启动一个简单的 Express Node.Js 服务器：

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",
)

当我跑

ibazel run //services/server/src:server

服务器启动得很好。但是当我更改一些代码并且 Bazel Watcher 重新启动时，我收到此错误：

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

因此，之前的 Node.Js 进程并未终止，端口仍在使用中。

• 我是否必须在我的 Node.Js 应用程序中处理终止？

• 或者是否有其他方法可以使用 Bazel Watcher 运行 Node.Js 代码？

• 还是 Bazel Watcher 的问题？

Answer 1

正如@Toxicable所说，我已经改为nodejs_image这样nodejs_binary：

load("@build_bazel_rules_nodejs//:defs.bzl", "nodejs_binary")
nodejs_binary(
    name = "server",
    data = [":lib"],
    entry_point = ":index.ts",
)

这解决了问题。
