Question: Recompile times

[ruohki]

Is it just me or are the recompile times rather slow?

20-30 seconds for me as of right now. As its rebuilding front and backend even tho there just changes in the backend

This plugin works wonderfully for me otherwise. Finally Decorators :>

[copleykj]

Are you only seeing full rebuild with this package, or does it also happen with the core typescript package?

[ruohki]

it feels like a complete recompile.

I have a repo setup at ruohki/meteor-graphql-mongoose-starter

saving a server while will recompile the whole thing leading to that wait time of 15-30 secs to view the outcome

[copleykj]

So as far as I can tell from cloning and running your repo, a full rebuild only happens if you change code that is imported into the server environment. Client only code results in a client rebuild and refresh as is standard build tool behavior.

Output for client only build

Notice here that compilation happens for web.browser and then the client is refreshed. After which web.browser.legacy deferred compilation happens.

Output for full rebuild

Here we get web.browser, then os.linux.x86_64 and then the we get a Meteor server restart. Finally web.browser.legacy deferred compilation happens.

As far as what can be done to speed up compile times, I can't speak on that as I'm not familiar. Possibly @perbergland, or other members of the community with build plugin experience, can shed some light on possible solutions.

Here is the log from the video, whole process is around 20 seconds until the webapp is browsable again. using --exclude-archs web.browser.legacy i can speed things up a bit but still

Yes, from what I see you are making a change that affects the server and thus there is a complete rebuild that happens. It is a bit unfortunate that it seems to take 20 seconds to accomplish this though.

[perbergland]

Can you test with the new 0.2.0 version to see if it made anything change?

[ruohki]

Dont seem to wield any performance boost. Still around that time. Still recompiles clientcode when i change a server file :/

[perbergland]

Please test again with v0.3.0 which should yield much better recompile times when running in meteor run or test+watch mode

[MastroLindus]

for our project, 0.3.0. improved speed a lot (before this release performance was just too slow compared to the official plugin, but now we are going to probably make the switch!) Thank you!

[perbergland]

I will close this issue soon since there are reports from the field that the performance is now OK

[perbergland]

Closing now since the report is for pre-0.3.0 and significant efforts were made to speed up the compiler
