Announcing Dancer2 2.0.0
by Jason A. Crome 16 Sep '25

16 Sep '25

At long last - Dancer2 2.0.0! I apologize it took longer than expected - open source doesn't always move as fast as we'd like it to - but there's a lot of great things in this release that make it worth the wait. Head on over to Perl.com to check out the details. Here's a quick summary of what's new: - New documentation, courtesy of a grant from the Perl and Raku Foundation - Extendable config system, thanks to Mikko Koivunalho - Removed Dancer2::Template::Simple from core Dancer2 - Retired our fork of Template::Tiny, and integrated our changes into the core distribution (thanks, @ether!) - Configurable data/secrets censoring with Data::Censor - Logging of hooks as they are executed - New hook: on_hook_exception - CLI improvements: - Changes that allow for scaffolding of other things (plugins, etc.) in future Dancer2 releases - Scaffolding of tutorial app We're really excited for this release, and we hope you are too! Keep Dancing! Jason/CromeDome and the Dancer Core Team

Community Review: Dancer2 Manual and Cookbook
by Jason A. Crome 27 Nov '24

27 Nov '24

We're getting into the home stretch of the Dancer2 documentation grant, and the first two documents are ready for public review: https://github.com/PerlDancer/Dancer2/blob/docs/doc-rewrite-grant/lib/Dance… https://github.com/PerlDancer/Dancer2/blob/docs/doc-rewrite-grant/lib/Dance… (please ignore the sloppy commit history; this will get squashed and cleaned up before merging) You are invited to discuss and provide feedback about these documents publicly or privately. Feedback can include (but is not limited to): - Misspellings - Quality and correctness of examples - Things that could be explained better - Things not explained at all You don't have to love it; in fact, if you don't, we'd like to hear why. In the longstanding tradition of the Dancer community, please be respectful. Actionable feedback is best. Thursday is Thanksgiving in the US. Between the holiday and other documentation work, I will not be looking at feedback until approximately December 6th, after which time I'll process, act on, and respond to feedback where it makes sense to do so. Thanks - your input and suggestions will help the next Dancers to learn all the best moves in the best way possible :-) Jason/CromeDome -- Jason A.

Dancer2 1.1.2 Released
by Jason A. Crome 25 Nov '24

25 Nov '24

Hi all, We've just released Dancer2 1.1.2 to address a few dependency and CI issues: * PR #1715: Update deprecated download-artifact (dependabot) * GH #1716: Remove Scope::Upper from list of recommended deps (Russell @veryrusty Jenkins) * PR #1718: Add Module::Pluggable as a requirement, excluding broken versions (Russell @veryrusty Jenkins) * PR #1719: Force install of Module::Pluggable so CI can successfully run (Jason A. Crome, Russell @veryrusty Jenkins) Module::Pluggable 6.1 and 6.2 is currently not installable as root, which may cause you issues during installation of Dancer2. We've opened a ticket, and are hoping for a speedy resolution. As the holidays approach (Happy Thanksgiving to those who celebrate!), we'd like to wish all of you a happy and safe season, full of fun, family, and, of course, Dancing :-) Jason/CromeDome, on behalf of the Dancer Core Team -- Jason A.

Announcing Dancer2 1.0.0
by Jason A. Crome 14 Nov '24

14 Nov '24

On behalf of the Dancer Core Team, I am beyond excited to present you with Dancer2 1.0.0. So how did we get here? Why now? I'll cover the specifics in a future blog post, but suffice it to say for now, we're stable, and we've been stable for a long time, but this was never reflected in our versioning. It's beyond time to commemorate that milestone. If you're expecting big changes, you'll be disappointed that there aren't many on the technical side. Much of what's in this release involves adding some polish in spots, and smoothing out some jagged edges in others. Some important highlights include: - We've enabled GitHub Discussions (https://github.com/PerlDancer/Dancer2/discussions) on a trial basis as a means to better provide support and greater interaction with the community - Going forward, Dancer2 is (doing a better job of) adhering to the Semantic Versioning specification (https://semver.org/) making our version numbering easier to understand (and that includes for us, the core team!) - The Perl Toolchain gang recently announced that going forward, they’ll be tracking the Perl of 10 years ago (https://rjbs.cloud/blog/2023/05/pts-2023-lyon-amendment-2-5/) We have decided to follow suit. That doesn’t mean we will deliberately break backwards compatibility; that doesn’t mean Dancer2 won’t run on old Perl versions, but if something breaks on a Perl more than 10 years old it does mean we (probably) aren’t going to support that. It also means that going forward you'll see some newer Perl idioms and keywords in the Dancer2 code, especially when it makes code easier to implement and understand. - We’ve updated our contribution guidelines (https://github.com/PerlDancer/Dancer2/blob/main/Contributing.md) providing new contributors with some more helpful guidance, and making our expectations for contributions clearer. - We’ve hard deprecated a mountain of old code (https://github.com/PerlDancer/Dancer2/milestone/27?closed=1) Hopefully you weren’t using it. The Core Team made some effort to either submit PRs or contact maintainers of plugins that are affected. For more details, please see the Changes (https://github.com/PerlDancer/Dancer2/blob/main/Changes) file. We've recently partnered with TPRF to make it easier to donate to Dancer2. We’ll have more details to offer about this soon, but TL;DR: donating to Dancer2 will now be easier to do, and donations will be tax-deductible. The Core Team hopes you’ll take advantage of this new arrangement and help fund future development of Dancer2 and its ecosystem. A number of bugs and minor enhancements have been made to our website (https://perldancer.org) in preparation for this release. We’ve got some additional incremental improvements ahead, but we hope you find this to be a nicer resource than it has been previously. There's a lot of excitement among members of the core team, and Dancer2 1.0.0 is just the beginning. We've got some awesome ideas coming to fruition in the weeks and months ahead. How can you help? Use Dancer2! Blog about it, tell your friends, especially your non-Perl using friends. Report bugs, send pull requests, improve the docs, donate some coffee or pizza or spare change... it all helps us to keep delivering. Thank you for being such an amazing community. You make this worth doing for all of us. Love, hugs, and, of course, the dance of joy (https://www.youtube.com/watch?v=z_5J1csi1AU) Jason Crome / CromeDome, on behalf of the entire Dancer Core Team -- Jason A.

HTMX, simplicity, stability
by Niels Larsen 03 Mar '24

03 Mar '24

Dancer2 developers, Are someone picking up on HTMX (http://htmx.org) like Django is doing? HTMX finally allows interactivity by the server rather than client Javascript. A great relief for us who think the best use of Javascript is minimal. I have made a rather large perl based single user DNA analysis package that is deployed in industry. Its results outputs are sets of text tables and corresponding inter-linked HTML files that the user can navigate. Lately the need for more interactivity and instrument control has come about, and then I thought of Dancer + HTMX. A simple route handler that calls my functions that produce smaller or larger pieces of HTML should be enough. No need for Plack, an "app" file layout, login, security, just a route handler where I can set the port number. Your tutorial, below this appealing script: #!/usr/bin/env perl use Dancer2; get '/' => sub { return 'Hello World!'; }; start; state "We want to emphasize that writing a script file like this with a start command is not how you would typically begin writing a Dancer2 app." But why is that? is there a speed problem? I will have my own cron-loop and could just make sure this runs in background, like I do with Apache web server. But I must be able to set the port at install time, since 3000 may be busy for other things. Also, the route handler will always be on localhost, i think. Finally, I see long-standing bugs on github and nearly no traffic on the mailing list. This makes me wonder if I dare base my package on it. Comments?

Dancer2 1.1.0 is released
by Jason A. Crome 12 Dec '23

12 Dec '23

Hey everyone, Happy Holidays! Dancer2 1.1.0 has been released and is on its way to CPAN. It has one really awesome new feature: named routes. With this update, you can name each route in your Dancer2 application, then refer to that route by name with a new keyword, uri_for_route. You have a lot of control over how this route is constructed, and can use it anywhere you were previously using uri_for. This helps you to avoid the need for lengthy URL references in your code, and makes it easier for you to build applications that are easier to grow, maintain, and later refactor. You can read more about it in the Dancer2 manual, or check out the pull request (https://github.com/PerlDancer/Dancer2/pull/1270) that introduced the change. As a bonus, the Twelve Days of Dancer (our mini-advent calendar) launches this week at https://advent.perldancer.org, and @xsawyerx has written a great article that covers this new feature and keyword in-depth. Happy Dancing! Jason/CromeDome -- Jason A. Crome / CromeDome CPAN: https://metacpan.org/author/CROMEDOME GitHub: https://github.com/cromedome Blog: https://cromedome.net

Web sites/companies using Dancer2
by Jason A. Crome 25 Jul '23

25 Jul '23

Hey Dancer Community! I'm looking to make some incremental improvements to the Dancer website (https://perldancer.org) starting with the dancefloor (https://perldancer.org/dancefloor) To be honest, I never really liked this page, and since many of these sites are now defunct, it really doesn't show well. Instead, it would be nice to show logos and provide links to sites and companies using Dancer directly on the front page of the site, with a second page that provides a more comprehensive listing. If you or your company has developed software with Dancer and want the world to know, please contact me directly here or on IRC and we can work out the details. Thanks all, and keep on dancing! Jason / CromeDome
