The pull request adds the --port option to run-ios allowing a developer to build and launch a react-native app using a single command line like this:

react-native run-ios --port 8088

It defaults to the current port 8081.

This pull request fixes issue #9145 and issue #14113.

This patch also extends run-android to properly test and launch the packager with the specified port, extending the work done in PR: ##15316

Test Plan

  1. Create a new react-native app, or simply clone this branch and then update your version of react-native using yarn add file:./path/to/this/fork/of/react-native
  2. run react-native run-ios --port 8088
  3. watch the packager start on the desired port (8088 in this case) and watch your app in your simulator connect to the packager and launch the app.

Thanks for the PR!

I think we should find a better way to pass the port when building the project, the current method is very likely to break in the future. The easiest way is probably to use the RCT_PACKAGER env variable with some xcode config magic that defines a preprocessor variable.

Also did we use the RCT_PACKAGER env var before? If not I think we should name it RCT_PACKAGER_PORT instead.

Rest looks good, just some small nits :)

Can we use a preprocessor macro instead of modifying the source? I think we already set the RCT_PACKAGER env var so we could use that, if I remember correctly there's some config in xcode to hook up defines to env vars.

good job :D

one question, how is this supposed to work with normal start and compile?
by that i mean, if i do yarn start 8082 that calls node node_modules/react-native/local-cli/cli.js start --port 8082 on the terminal, and then go to xcode and press run, will that work? would i have to put 8082 somewhere else manually?

this is a nice thing for running a production build on the same machine that you are developing at the same time. you develop in one port running the scheme with that port, and you have another port and a compilation for that other port.

@DaKaZ
Copy link
Author

DaKaZ commented Nov 3, 2017

@pvinis the easiest way to do this is to not run start and run in separate processes. Instead, you can simply do this and it will start the metro packager:

react-native run-ios --port 8082

If you have already started the packager, you would need to tell your build with the port number the same way as above.

pvinis commented Nov 4, 2017

I don't work with run-ios. I prefer to start the packager and then run from xcode because I need to do changes on the native part.

if I can suggest a change in the pr, it could be to extract the ifndefs to a file, so they are not copy pasted in so many places. better to centralize these kind of constants.
thanks.

@syzer that does not work with McAffee unless you run your RN development in a docker container. I work in a secure environment and we have to patch react-native after every yarn install to use a different port - thus the motivation for fixing this.

Paging @samwgoldman @hramos @sahrens -- this is a highly desired issue (just google search "react native port" to see) and the PR author has been waiting nearly a month just for feedback in order to complete this PR and get it merged into master.

Can we please get this PR assigned to a different set of reviewers who are more available?

Contributor

hramos commented Dec 20, 2017

Hey all - @shergin is one of our engineers in the React Native team and has provided a lot of feedback on the PR, so I'd hardly say this has not gotten attention from our team. We have to be very careful when merging PRs to ensure they do not introduce issues, especially around holidays when fewer people may be around. Hang tight and we'll get back to this PR soon.

@remyrylan
Copy link

@hramos The issue definitely did receive attention, it's the fact that it's been 27 days since @shergin has responded to requests for further feedback. No one is discrediting the hard work that @shergin and the rest of the team does -- we're all very grateful and respect the talented contributions.

The particular concern here is that with 27 days without feedback, we start getting into territory where the PR runs the risk of becoming a waste of time as the author has to not only wait on feedback but also keep up-to-date with incoming changes within the master branch that may break their changes.

Point being: if we all want to foster the spirit of the community being involved, we need to avoid unnecessary burden for volunteers. If PRs are going to take longer to review, perhaps the RFC strategy adopted by React recently is a better option where decisions can be discussed in the open and once a consensus is reached, then development can begin by a volunteer or staff.

DaKaZ commented Dec 20, 2017

@hramos I did not mean to disrespect @shergin - I do recognize the massive amount of work going into react-native and the number of PRs that are merged daily. Admittedly, I am a bit jealous that other PRs get so much love so quickly, but thats really just an ego issue I'll need to work through.

The problem here is that the review was not very timely and it is incredibly vague - I asked follow up questions almost immediately so that I could conform to the proper standard and better understand what (if any) issue was raised. And there is nothing - there is no guidance on how to proceed, no expectation that it might be weeks or months before more feedback can be provided. Let me ask you, how do you respond to a code review comment like this one:

Maaaaaagic...

That is not helpful. So yes... I am a bit frustrated, I want to contribute not only this PR but others in the future. So please take this as constructive criticism, we can all improve, my self included :) If its going to take a month or two before a PR is reviewed because of the holidays, competing priorities, or you just don't like the author - great - just state that. Thats all I ask...

The process for figuring that out is the same for any commit:

  2. Scroll down and look for the list of tags

screen shot 2018-01-19 at 11 43 32 am

In this case, you can see it's tagged with v0.53.0-rc.1, meaning it's already part of the 0.53 release.
