so the and and
8 year old at all possible there when your name and so embassy alive but his images Courtesy this morning working on a slide that late works pretty well and people or submitting pictures of what you should maybe have a a title screen so this is from Mike Mike partly this remain wonderful isn't they the
so who here went to the morning workout the right so I I figured this would happen so every in a stand up downward and you jump on it the tomorrow that they were all going to go to the gym tomorrow right so that's me on the Internet
I don't actually have glowing star things but I feel if I changes then people recognize me an infinite so it'll be there forever I
I I I like amber I work on member alive and pretty much anything else people let me work on I I'm a crazy my wife
loans knelt open-source often so we should think here the I I work at and largely work
on Amber at the Austin stewards of my open source work it's been fantastic the recently I also started
attending TC 39 has been pretty intimidating so but learning a lot I think we're in good hands UTC 39 JavaScript will continue to become better and this is good and
that throughout the talk feel free to ask questions but be mindful we only have you know 30 minutes and and if I can answer your question during this talk and finding afterwards I would love to talk about this stuff and so the we have a little bit of history with build tools in the front end world especially the amber previously stroke or world so back in the day we had a stroke or tools that is the question who here spoke the but I spoke long-term who suffers change and who remembers this guy BPM ac author that this was a truly ambitious project maybe a little bit too ambitious and unfortunately all that remains is this archive . org thing that actually goes around but but was lots of things from there were starting to finally realize now many years later so rate pipeline this guy happened use
like staff stop it is revealed tools so we can blame or congratulate and thank Chris 4 embassy lies it is today in the
no no I did not so there is ever tools with common congestion then there was a member acting and the selling the 2 here really was year 6 models so the 1st time a big framework have dedicated entirely to using these 6 models in a personal like has really more thing and I think in retrospect I think who told me was the right thing so basically the proportion of the that direction who here for yes you use them bracket here but it's a more than stroke or here enjoyed the upgrade process the add-ons build performance then it left something truly to be desired and that to sorry
about that also the while that commercialize you
about 0 . 0 appeared the and
given and becomes talk here about 2 years ago some time there is more or less vaporware
and thanks to people like Joe theory who also shared his belief that we can make something cool here and the rest of the community it actually became a real thing and a set of curiosity who here is building embryo and not using embassy alive I think there's 1 2 3 3 yes I can we should talk and so even 2 years and I gave a talk of like uh will this new those thing people are going to use but since the working but In this time we have tried for relentless quality and I think we set a good bar for web dev tool should be in this environment and 1 important detail I think is
often forgotten in the U X is important but it's also extremely important for
developers the it we coined the term dx I went on Urban Dictionary nature wasn't anything very inappropriate so we can probably be accessed a developer experience and or the and now we have to place were generally embassy like so for the 3 people here the is the de-facto foundation for building our ambitious web applications and some cool stuff it's actually being explored by some others in the domain so angular still eyes currently exploring using it there's actually unofficial reacts that uses it and I've seen a few others so I think today we we have a little the street cred this idea works and yet simple statistics so in its existence there's been 207 thousand 754 closed issues 202 thousand 817 close all requests 321 contributors this is possible now there's more than 321 people at this conference so come on guys the mode of 5 thousand units 92 releases over 2000 public adults and companies likely did any of you have a high number of internal analyses well suspect this number might be a little bit higher and since the beginning of time there's been about 100 million library it's so the number con gave yesterday is totally factual in the last year or so we've done about but 50 million but since the beginning of time and then about 100 million light to bring the number of so I don't think these numbers were just fluff or vanity metrics and they are in the field they should make all of you feel good as well but the real values they are the principal for future investments they justify our past investments and I hope they enable confidence in everyone here and everyone in the community at large In continued future investment no warning but a
matter and although I have lots of Mac experience apparently simple laughter it's hard to know so use Google and stuff so if there's something wrong in these next numbers on be so embarrassed that this pretend like the right to the
the so imagine With this large user base at about 100 million reloads if we do a 20 % build improvements and if assuming the average builders about a 2nd we saved over a thousand days of developer time but sorry that is totals about thousand developer days and reason about 200 nobody's that's cool the and we've seen some performance improvements in last year but I'm pretty sure that the 2 developers they gave it to 2 months or so time at most it's wholly realistic for us to see another 5 x or even 10 x improvement in this space that's a lot of time big number slots and they said but we can actually justify that time it is also worth noting that not all all developers work 24 hours a day 365 days a year so the numbers are even more in our favor on average I think developers are productive for 4 to 5 hours a day if they're not holding into too many meetings so that's and collaborative so that's more pedantic let's continue to invest and someone's we can project will benefit everyone in this room and beyond so with this type of leverage being pedantic really pays off we have contributed to countless third-party libraries of the rest ecosystem uses human or find a custom windows node and plot locks incoming actually duty and it's basically countless so you know we have Aubrey specific tool chain are users of this tool chain our investment in this children is improving the node ecosystem and development ecosystem at large again this this gives us the prime that
we need we can justify the time and not really in the
2nd part of my talk and talk about little bit of a retrospective what has worked in the last 2 years but has worked and learn steps so I think we can probably all agree that these things have worked the sort of batteries included experience I get sad when I see the someone needs 3 or 4 years of branches something experience in the job posting I mean I think Grant is a great tool we use a number of the but let's be honest if being 11 nobody means you must have 5 years of school experience using the build tools that I think we may have missed the point the system thing is working quite well being bullish on reinvestment in our own tech and tech that we use and most importantly endosome community so what has kind of maybe kind of work by accident a little bit OK usually is the stability of embassy I but I'm only saying this because compared to number active it's wonderful but we have to be honest here it must become better
the and what didn't really work at all I think this is largely my fault is enabling the community at large and some of the larger efforts I have found it quite difficult to delegate communicate line pensions write down share responsibility and it shows it the dependency management story that leaves something to be desired who said we need to package managers to be successful here abundance interest who here these HF that OK I'm sorry and broccoli plugging perfect by default and the Windows experience I think it is not quite at the level that we want as it it's a promise ability active development risks instability what is in the recipe for success and as you want accelerator productivity we have fixes the solution is straightforward a copy embers release channels problem of enabling a community at large delegation knowledge and a hard so the solution is obvious Cheryl things but it's harder than that but we solution and that is the embassy like 40 we published weekly minutes we do all of our communication embassy alive or dead embassy lie on communities lexicon come Popeye and of public works the process this is our
embassy like 40 the so and that's a few characteristics of people the war and nations here I Chad's boyish good looks it who the people of that but this is the last slide made this morning publishing and so this is I think a recipe for
community in successive years and quirky open communication arts process and release channels I think this will enable a community and allows to be successful now the next fall was bouncing Bauer PM so balancing gaps between 2 Tupac advantages qualities of 1 of our package managers can even do it the the but we still actually have to do you think with dependencies from power so I think the solution is us bowel those but they are trajectory should be to transition away transition largely Dantean encourage and the empty and dependencies and move our support to an embassy Aladdin on now there's a lot of Adams existing that depend on our I think what will this do for the time being although detectors and install this out on on the fly so it'll continue to transparently work but the fold embassy lines all small degree about our next thing the people come up to me in the sense that map is pretty you something about this and I I still think that's actually too big the so are happening date I think is a sign of success building really large truly comprehensive systems there are going to be big I know and yet we have some projects 2nd at anywhere from 12 251 developers working on and the problem it just expands the stealing quite well but really single files don't scale so 1 of the tricky problems here is defining the boundaries automatically I think our solution is pretty obvious engines and sink engine so the work that done part Robert been doing real work hard to make sure that embassy like can provide the foundation for automatically producing bundles for Indians and also exposing some better lower level API to craft a room composition as required and yet the legal system has an efficiency escape valves the whole thing Chad actually built a proof of concept of a package a linker solution last year that exposes and we're hoping to resurrect that effort this year and make it a real thing this should also enable in his proof of concept he actually enabled h e 2 serving in other experiments so I hope that we can bring this to the general community or large and these code no think this is the 2nd part of Chad's work exactly the linker so this allows property to be aware of the contents of files and choose the appropriate files be part of your build based feature of you know this should have worked the the I'm very sorry
that should have worked I think really what happened
1 of the biggest thing pointers surprisingly STG and base Asia just procedure like each other and this is the thing simple in a standard but we need a short term solution and rob proposal and I think that's pretty good doing asset rewriting both in Devon progess to fix the problem that is going to fix this problem kicking pull for keeping instruments were going to make it work now the next thing I think this is worked out very well for us some aspects of it thing can be improved still but I want explain a little bit wide we
use broccoli the so when 1 adjustable pipeline we want to be able to share its experience around pipeline wanted to live focus on a single responsibility module that does 1 thing 1 thing very well so broccoli it can be sometimes displayed as react for the file system so we want to build pipeline that
composers so this is a real example where 1 day is like a set of steps and bring limber integrated like other problems all this literally required reveal pipeline find it merged with members in done the pretty easy and this is really cool cover that take stripped entirely built built by 1 that is just to work I can develop when would remember at the same time and would include any internal
knowledge to this actually all of our Adelind's introduce their own bill but once and most people don't notice OK that status killing the of goodness of so every at this is actually empty episode is Nancy this is would probably knows come home but don't panic all goodness and the other time because this filtered but OK so this is what computers are made for and everything of man and it's just the
this and I'm sorry should have added that image at the last minute bear with me there's OK the so so computers are made for all this actually happens in 100 in 100 150 ms but we can actually so make it way faster so this quick properly primer and this is the most basic property pollen or brought pipeline I could think of we want to babble everything in the directory engineers centered so what basically happens we take a directory
we throw into battle Jason comes at the end some 20 multiple inputs like merge so combine multiple passes and use of that this so the external API doesn't expose any internal so the implementation from the outside the public area is really without too many public to me fundamental per problems but the plug-ins do all of the work but a small number of people actually have to use the pollutants so when we improve plug-ins so we can actually do so without breaking people applications this is a when we can still be somewhere here but it's a when so how do we actually make them fast so I was a bit pedantic and spent 2 full weeks last year authoring tooling for a properly so last year if you remember people's accident-prone again and people were experiencing 20 30 second règles on POS existence and that's not cool so I started added there's a big at the 30 35 seconds of rebuilds this model so they give me the time and I was pedantic there are some ideas about what the performance problems were but I really wasn't sure but after this instrumentation landed is blatantly obvious what the problems were so now there's some called debugging tools called diagramming tools but it actually been quite useful so what was actually slow here well the interface between Brock according to the file system the during the static told you that the fossils and pretty slow the 3rd it by be a process matches and slow it's always so if you really have to use it and it turns out properly was taking advantage of some features of our system that it didn't need to be can be a little bit more telligent Auerbach opponents we can get some pretty good provided the breaking people that's so In this system or but some prevented and using the developer tools I mentioned earlier I came up with Robert plug-ins that apply patterns rather than having to rewritable output directory and this was good the 32nd pottery bowls drop in the 600 ms so that's it thank so I actually supplied in that is actually a group of people at work on it and is taking all the credit for I guess and Chad high color and David Hamilton were super instrumental in making network but and but in the end we ended up with upwards of 50 x improvement and in some situations more in some cases lowly less that might have that we use at work it had this performance characteristic improvement yeah cool thing is with this instrumentation can actually definitively say that even those external 2nd sounds cool for happen has like an old couple hundred 3 to 5 thousand lines of jobs act code but I can tell you that 70 per cent per cent of the time is still wasted so that means we we could conceivably see an app that size rebuild under 100 ms what this means is From a build tool standpoint we have a lot and we collect some really big apps stroke and be totally successful if we combine that with engines and bundling can be pretty cool so what's next so brought the plug-ins right now they're kind of the largest in Canada spending is actually reading the input tree from the fastest so the solution again without shake changing a breaking the public API for problem just updating plug-ins is to have more plug-ins instead track the changes rather than getting the input output the input the and this is basically the remaining time this is non-trivial work but we can do the another thing window support for broccoli I think we've come pretty far we have their builds thanks to every tallies company was the needed at their bills sources have been invaluable and other accuracy who here uses Windows and broccoli it is the experience like OK as if it could be better definitely so we've been working pretty close with Microsoft who happens like embers end 0 some of the tensions here on this train tracking and diffing stuff they actually will remove the need for some links in broccoli and tons of disk I O and I think this is going make a really big difference on Windows systems as is but today
if you're following the news our friends at microsoft had a really cool announcements and that is windows 10 users will soon be able to basically just be able to run an actual batch and belief and a little bit physiology there so Felix feel free to correct me but I believe it is bundled bond binaries and transparently make all this work and not such so yesterday I heard heard rumors of this this this last mile in the woods space I knew he couldn't tell me something and then this morning I got a frantic set of tweets a in 101 latitude latitude than in the news broke I can tell you now that for any set equal screenshots mattered here but for diseases this is the fantastic and anyways is not
part that is the although the broccoli performance improvements have landed the benefits are still not for everyone in this room I think it is probably not a good reasons other than more work on my behalf and on your behalf but everyone's bills you should be sub-second time adults the if you're not there yet nature readers performance God and I think that this so if you brought the plug-ins that little bit inefficient because it's a little bit too tricky to write these new types of brought on so another ongoing effort that have of help with is to come up with a better a set of tools for brought the plug-ins to use just to do the right thing correctly you the everything words we want the rocket plugin authors to fall into a bit of success by default not require Robert for myself to go and fixed every rock plug-in in existence coming up with is a tricky for anyone who's interested in the me on Twitter find us in the embassy of Dev channel on slack open issues I would love to work with a group of people to figure out what this API can be so that everyone who writes a profit but it will get fast performance planning by people so that was an example being pedantic scratching my own which my have was slow pretty worth of 50 x performance improvement that's also with this countless examples of that in embassy alive for example Eric trom spent a few spent a lot of time making sure that Port Finder implementation work yeah she went fix the Port Finder he learned how all of these details work on Linux and all Windows and OS X and I think if he was just working on his own project he wouldn't have been able to justify the investment but because investment benefit everyone in this room and beyond it was totally worth it and it was totally justified and is super excited when Apple request landed so come help us invest in the SDK for the web thanks few as few few the question was is embassy alive 113 embassy like 2 . 4 compatible with 113 applications so this is probably under-documented but embassy lie has very little coupling timbre itself so it's totally possible although maybe undocumented to get an amber 113 or amber 1 . 0 applications working on the latest version of embassy or we actually did a great reversal working now assistance holding back as it was very clear as to whether you were using anything was afraid that may be under the covers you might use some feature that it's not available yet yes the answer is totally know it would have worked maybe a little bit of massaging dependencies but the 2 . 4 branch of embassy I will only be able to build a 1 x 13 per member in the 2 x series of embassy allow actually working to the cup with even more so blueprints l'action deeply into your version of amber and paint remember data so if you have a 2 . 4 version of embassy lie in some other version of Amber Amber data will get the appropriate blueprints for that version of amber thanks to the prom any other questions was since there's no questions I'm really excited to see all of you as new contributors because it is very much and I hope you enjoy the rest of the buffets so in my eye
