Update April 15, 2020: Still go for May 13.
Update March 6, 2020: There's a difficult balance to be had between trying to get it right and shipping a usable product. The repository continues to see rapid development and we have yet to make substantial progress on the major missing feature: dev tool support. Therefore we are bumping the release date yet again. However instead of blindly estimating several weeks out, we've discussed it at length and decided 2 months would be enough time. This coincidentally is around the 2 year anniversary since the first commit. Therefore we are setting the date of May 13, 2020 as the 1.0 release date. Contributors are encouraged to get any major API changes in before April 20 - after that date we will be polishing and bug fixing. Of course the API will continue to evolve and improve after 1.0, but we will be making explicit stability guarantees for some interfaces.
Update Jan 27, 2020: Massive progress is being made, but we still have not yet accomplished the major feature blocker: devtool support. I hate to keep kicking the release date, but we're still looking at some weeks of development. We hope to ship a 1.0 build with stability promises towards end of February.
Update Dec 23, 2019: There is one major feature we lack that needs to be in 1.0 - that's a way to hook Deno up to Chrome DevTools. Implementing it has induced a rewrite of the bindings to V8 - that work is ongoing https://github.com/denoland/rusty_v8. We want to fork lift Deno onto that system before 1.0 happens. Current estimate for 1.0 is end of January.
[x] replace libdeno with rusty_v8 https://github.com/denoland/deno/issues/3530
[x] "deno --debug" https://github.com/denoland/deno/issues/1120 We need to be able to debug using Chrome Devtools. As the deno userland code base grows, it becomes in increasingly painful to work without a debugger. The way this will work is with a websocket server in Rust (port 9229) which forwards messages to V8 (using V8InspectorClient). https://github.com/denoland/deno/pull/4484
[x] Loading and execution of modules (either JS or TS) needs to be correct. This is the main thing we deliver actually, but there are still many bugs:
source maps are sometimes incorrect https://github.com/denoland/deno/issues/2390, double downloads happen https://github.com/denoland/deno/issues/2442, the cache needs to be refactored https://github.com/denoland/deno/issues/2057.
[X] Import maps. It's a very reasonable standard and we can provide support via a command line flag. This allows bare imports. The feature will land very soon https://github.com/denoland/deno/pull/2360.
[x] Dynamic import. 50% complete at the time of writing. https://github.com/denoland/deno/issues/1789
[x] "deno test" test runner https://github.com/denoland/deno_std/issues/193
[x] "deno fmt" is slow on the first run. It download a couple of large prettier bundles. https://github.com/denoland/deno/issues/2490
[x] We need to support d.ts files https://github.com/denoland/deno/issues/1432
[X] "deno bundle" outputs a single AMD bundle of your program. This is useful to share code with websites. Early work has started: https://github.com/denoland/deno/pull/2467
"deno compile" is a very interesting feature to output an executable. It would be nice to have, but I would let this slip past 1.0. https://github.com/denoland/deno/issues/986 Not for 1.0
[x] "deno install" is a program that creates little shell script aliases to deno programs in your $PATH. This let's people distribute their code easily. https://github.com/denoland/deno_std/issues/471
[x] dlopen / plugins / extension modules. We need some way of calling into Rust land. The way Parcel does it is pretty awesome https://parceljs.org/rust.html - but we need low-level primitives to build that on, as we need to carefully funnel everything through the Op abstraction. @afinch7 has a working patch for loading ops in DLLs https://github.com/denoland/deno/pull/2385, we are still iterating on the exact API. I would allow a true FFI module to slip past 1.0 - we'll get there - but it needs to be built on ops. https://github.com/denoland/deno/pull/3372
[x] Support TLS https://github.com/denoland/deno/issues/3009
[ ] The web-server should be faster.
[X] When you visit a deno.land script url (example https://deno.land/std/http/server.ts) in a web browser, it should do better than redirect. It should look at the Accept header and serve pretty HTML. Solved in https://github.com/denoland/registry/commit/b78e6ae331004859aad7b01ed452f6b00265b035
If you use "docs.deno.land" you will get auto-generated docs. https://github.com/denoland/deno/issues/3094 https://github.com/denoland/deno_website2/pull/49
[x] typescript dependencies are not loaded in parallel
[x] signal handlers https://github.com/denoland/deno/issues/2339 #3757
[X] fs events https://github.com/denoland/deno/issues/1826 #3452
[ ] TS and source maps are correctly recompiled https://github.com/denoland/deno/issues/2945
[x] Remove tokio_util::block_on https://github.com/denoland/deno/issues/2960
[x] "deno test" is slow (when running on std) https://github.com/denoland/deno/issues/2789
[x] deno lock file https://github.com/denoland/deno/issues/200
