|
||||
|
||||
A tool for respawning node binaries when special flags are present.
|
||||
|
||||
## What is it?
|
||||
|
||||
Say you wrote a command line tool that runs arbitrary javascript (e.g. task runner, test framework, etc). For the sake of discussion, let's pretend it's a testing harness you've named `testify`.
|
||||
|
||||
Everything is going splendidly until one day you decide to test some code that relies on a feature behind a v8 flag in node (`--harmony`, for example). Without much thought, you run `testify --harmony spec tests.js`.
|
||||
|
||||
It doesn't work. After digging around for a bit, you realize this produces a [`process.argv`](http://nodejs.org/docs/latest/api/process.html#process_process_argv) of:
|
||||
|
||||
`['node', '/usr/local/bin/test', '--harmony', 'spec', 'tests.js']`
|
||||
|
||||
Crap. The `--harmony` flag is in the wrong place! It should be applied to the **node** command, not our binary. What we actually wanted was this:
|
||||
|
||||
`['node', '--harmony', '/usr/local/bin/test', 'spec', 'tests.js']`
|
||||
|
||||
Flagged-respawn fixes this problem and handles all the edge cases respawning creates, such as:
|
||||
|
||||
- Providing a method to determine if a respawn is needed.
|
||||
- Piping stderr/stdout from the child into the parent.
|
||||
- Making the parent process exit with the same code as the child.
|
||||
- If the child is killed, making the parent exit with the same signal.
|
||||
|
||||
To see it in action, clone this repository and run `npm install` / `npm run respawn` / `npm run nospawn`.
|
||||
|
||||
## Sample Usage
|
||||
|
||||
```js
|
||||
#!/usr/bin/env node
|
||||
|
||||
const flaggedRespawn = require('flagged-respawn');
|
||||
|
||||
// get a list of all possible v8 flags for the running version of node
|
||||
const v8flags = require('v8flags').fetch();
|
||||
|
||||
flaggedRespawn(v8flags, process.argv, function (ready, child) {
|
||||
if (ready) {
|
||||
console.log('Running!');
|
||||
// your cli code here
|
||||
} else {
|
||||
console.log('Special flags found, respawning.');
|
||||
}
|
||||
if (process.pid !== child.pid) {
|
||||
console.log('Respawned to PID:', child.pid);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
### <u>flaggedRespawn(flags, argv, [ forcedFlags, ] callback) : Void</u>
|
||||
|
||||
Respawns the script itself when _argv_ has special flag contained in _flags_ and/or _forcedFlags_ is not empty. Because members of _flags_ and _forcedFlags_ are passed to `node` command, each of them needs to be a node flag or a V8 flag.
|
||||
|
||||
#### Forbid respawning
|
||||
|
||||
If `--no-respawning` flag is given in _argv_, this function does not respawned even if _argv_ contains members of flags or _forcedFlags_ is not empty. (This flag is also used internally to prevent from respawning more than once).
|
||||
|
||||
#### Parameter:
|
||||
|
||||
| Parameter | Type | Description |
|
||||
| :------------ | :-------------: | :--------------------------------------------------------------------------------------- |
|
||||
| _flags_ | Array | An array of node flags and V8 flags which are available when present in _argv_. |
|
||||
| _argv_ | Array | Command line arguments to respawn. |
|
||||
| _forcedFlags_ | Array or String | An array of node flags or a string of a single flag and V8 flags for respawning forcely. |
|
||||
| _callback_ | function | A called function when not respawning or after respawned. |
|
||||
|
||||
- **<u><i>callback</i>(ready, proc, argv) : Void</u>**
|
||||
|
||||
_callback_ function is called both when respawned or not, and it can be distinguished by callback's argument: _ready_. (_ready_ indicates whether a process spawned its child process (false) or not (true), but it does not indicate whether a process is a spawned child process or not. _ready_ for a spawned child process is true.)
|
||||
|
||||
_argv_ is an array of command line arguments which is respawned (when _ready_ is false) or is passed current process except flags within _flags_ and `--no-respawning` (when _ready_ is true).
|
||||
|
||||
**Parameter:**
|
||||
|
||||
| Parameter | Type | Description |
|
||||
| :-------- | :-----: | :------------------------------------------------------------------- |
|
||||
| _ready_ | boolean | True, if not respawning and is ready to execute main function. |
|
||||
| _proc_ | object | Child process object if respawned, otherwise current process object. |
|
||||
| _argv_ | Array | An array of command line arguments. |
