JSON 文件中所有进程的 PM2 通用设置

Question

我目前正在使用 pm2 启动多个 Node.js 进程。这些进程定义在 JSON 文件中，运行

使用该文件

pm2 start pm2.json

从下面的JSON文件可以看出，有很多重复。例如，更改 error_file 位置或将变量 time 设置为 true 涉及大量重复，如果在 JSON 文件.

是否可以通过在文件中仅设置一次 time 变量并将其应用于所有进程来简化 JSON 文件？

另外，是否可以使用模板来定义error_file和out_file，比如"../logs/${name}-error.log"？

例子pm2.json

{
    "apps": [
      {
        "name": "foo-a",
        "script": "./foo/a.js",
        "args": "-e apple",
        "error_file": "../logs/foo-a-error.log",
        "out_file": "../logs/foo-a-out.log",
        "time": true
      },
      {
        "name": "foo-b",
        "script": "./foo/b.js",
        "args": "-e banana",
        "error_file": "../logs/foo-b-error.log",
        "out_file": "../logs/foo-b-out.log",
        "time": true
      },      {
        "name": "bar-c",
        "script": "./bar/c.js",
        "args": "-e cranberry",
        "error_file": "../logs/bar-c-error.log",
        "out_file": "../logs/bar-c-out.log",
        "time": true
      },

      ...

Answer 1

您可以使用 js 文件代替 json 文件，它将允许您为 repetition part.

创建和使用通用 variable/function

const time = true

module.exports = {
    "apps": [
      {
        "name": "foo-a",
        "script": "./foo/a.js",
        "args": "-e apple",
        "error_file": "../logs/foo-a-error.log",
        "out_file": "../logs/foo-a-out.log",
        "time": time
      },
      {
        "name": "foo-b",
        "script": "./foo/b.js",
        "args": "-e banana",
        "error_file": "../logs/foo-a-error.log",
        "out_file": "../logs/foo-a-out.log",
        "time": time
      },      {
        "name": "bar-c",
        "script": "./bar/c.js",
        "args": "-e cranberry",
        "error_file": "../logs/bar-c-error.log",
        "out_file": "../logs/bar-c-out.log",
        "time": time
      },
