name: '🐛 Framework Bug' description: Report a bug in Mithril.js core assignees: dead-claudia labels: - 'Area: Core' body: - type: checkboxes attributes: label: Is there an existing issue for this? description: Please search to see if an issue already exists for the bug you encountered. options: - label: I have searched the existing issues required: true - type: input attributes: label: Mithril.js Version description: | Provide the exact version of Mithril.js you're experiencing these issues with. This matters, even if it's really old like version 0.1.0. Do note that bugs in older versions are commonly fixed in newer versions, so you should try to test it against the latest version if you can. validations: required: true - type: textarea attributes: label: Browser and OS description: | Provide the name and version of both the browser and operating system you're experiencing these issues with. If it's multiple, feel free to list multiple. This matters, even if it's super ancient. validations: required: true - type: textarea attributes: label: Project description: | (Optional) Provide a link to your project, if it happens to be open source or if you created a repo somewhere that we can look into further. If it's spread across multiple repos or projects, feel free to list them all. - type: textarea attributes: label: Code description: | What did you try? What code is causing the unexpected behavior? Make sure to try to reduce your code as best as you can while still reproducing the bug, so we can more accurately determine the cause. Ideally, it should just be a bunch of Mithril.js calls with virtually no logic at all, but it's sufficient to just remove unrelated network calls, attributes, and the like. In addition, make sure the bug still persists with the latest version of Mithril. If it's an older version, the bug may have already been fixed. If you'd prefer, replace this code block with a link to a code playground like any of these: - Flems <https://flems.io/mithril> (stores everything in URL hash) - JSFiddle <https://jsfiddle.net> - CodePen <https://codepen.io> - JSBin <https://jsbin.com> - Plunker <https://plnkr.co> - Glitch <https://glitch.com> (supports backend) - CodeSandbox <https://codesandbox.io> (supports backend) Or if it's a remote development project on your own server, feel free to provide that if it's serving unminified code we can look at. If it's a closed-source repo, it's okay to censor names and pull out irrelevant logic - we'd rather not sign NDAs just to see the code you're having trouble with. We do still need code of some kind that triggers the bug you're running into. render: javascript validations: required: true - type: textarea attributes: label: Steps to Reproduce description: | What steps need to be taken to reproduce this behavior?
