Backlog for DC Leaflet Code Sprint.

Leaflet Code Sprint Backlog

Functionality

  • Release 0.6 stable
  • TileLayer / GridLayer refactoring
  • Projections refactoring (removing spherical Earth hardcode, making flat maps usage simpler)
  • Rebuild Easey-style animation capabilities
  • Resolve issues with the opacity API (#1474) so that we can reliably use setOpacity with multi-layered maps
  • Decide on improvements to the geoJSON layer API that let users manipulate layer contents without being exposed to LayerGroup APIs.

FitGrit — a minimalistic fitness logging app that stays out of your way (concept)

FitGrit

FitGrit is an upcoming minimalistic app for tracking your workouts that stays out of your way.

This document describes the concept. I'll start developing it as an open source app once I figure out all the basic details of the concept.

The idea came out of frustration from existing fitness tracking apps and a simple Google Drive spreadsheet that I found much more convenient despite not being tailored for fitness.

Main concepts:

Leaflet 0.7 and plans for future

For the last and the ongoing week, apart from a few days speaking at a conference in Tallin, I've been focused on pushing Leaflet towards the next stable release, 0.7.

This is a bugfix-heavy release — as Leaflet becomes more and more stable feature-wise, the focus shifts towards stability, usability and API improvements over new features. I've also been holding back some of the planned deep refactorings (which I'll talk about later in the post) until 0.7 is released, so that the heavy risky stuff is done at the beginning of the release cycle, leaving plenty of room to catch bugs and incompatible changes that can unintentionally break existing apps.

0.7 changes

Leaflet vector layers refactoring

Leaflet vector layers refactoring

The goal is to refactor vector layers code in Leaflet to make it possible to use different rendering backends (Canvas, SVG, etc.) for different layers on the same map and switch between them easily, in addition to much cleaner and more transparent code. This will also open it up for interesting extensions, like custom shapes, indexing layers with RBush for fast interaction features, etc.

This is the file structure / responsibilities breakdown I currently have in mind for this.
