Extension Development Changes

• We have rewritten how extensions provide keyboard shortcuts and interact with the settings system. If you previously defined keyboard shortcuts or used the settings mechanism, you will need to update your extension (#5470, #5298)
• We have renamed the plugin type from JupyterLabPlugin to JupyterFrontEndPlugin. The application arg is also renamed from JupyterLab to JupyterFrontEnd and some its functionality has been moved to a separate ILabShell plugin (#5845, #5919)
• The lab shell addToMainArea, addToLeftArea, addToTopArea, addToRightArea, and addToBottomArea functions have been replaced with a single add() function that takes the area as an argument. Replace addToMainArea(widget, options) with add(widget, 'main', options), etc. (#5845)
• Rename pageUrl to appUrl in the server connection (#6509, #6508, #6585, #6584)
• MainAreaWidget instances now forward update requests to their content (#6586, #6571)
• The theme data attributes are renamed and moved to the document body element. If you are relying on these attributes in CSS to conditionally style based on the theme, you should update their names. For example data-theme-light is now data-jp-theme-light. (#6566, #6554)
• Extensions which require CSS should no longer import their CSS files into their Javascript files. Instead, they should specify a root CSS file in the style attribute in their package.json, and JupyterLab will automatically import that CSS file. (#6533, #6530, #6395, #6390)
• Dialog.prompt has been replaced by a number of type-specific dialogs such as InputDialog.getString, InputDialog.getBoolean, etc. (#6522, #6378, #6327, #6326)
• When a RenderMime widget is re-rendered, the default behavior is to remove any existing content in the DOM. This can be overridden if needed. (#6513, #6505, #6497)
• We have updated our internal TypeScript version to 3.5.1 and our compile target to ES2017. Extensions may need to upgrade their TypeScript version and target as well. (#6440, #6224)
• We have updated the typings for some of the Kernel messages so that they better match the spec. (#6433)
• A connectionFailure signal has been added to some of the manager classes, which can be used to detect when a connection to the server is lost (#6399, #6176, #3324)
• Add rate limiting and polling utilities to coreutils to use for throttling and debouncing of API requests (#6345, #6346, #6401, #6305, #6157, #6192, #6186, #6141, #3929, #6141, #3929, #6186, #6192, #6401 ,#6305, #6157)
• Require session when instantiating terminal widget (#6339, #5061)
• Provides a signal to see what items are opened in a directory listing (#6270, #6269)
• Ads the ability to add widget above the main work area to a top header area (#5936)
• Renames contextMenuFirst to contextMenuHitTest in the JupyterFrontEnd (#5932)
• Removes the initialCommand arg from the terminal creation command. (#5916)
• Adds --jp-code-cursor-width0, --jp-code-cursor-width1, and --jp-code-cursor-width2 variables to the themes to support changing the cursor width if you change the font size (#5898)
• Adds the ability to insert a new item to the toolbar before or after another item (#5896, #5894)
• Adds the ability for extensions to register new CodeMirror modes (#5829)
• We have removed the JUPYTERLAB_xxx_LOADER Webpack loaders, instead you should use the loader directly in the URL as Webpack supports it (#5709, #4406)
• Adds the ability to handle fragments for document widgets (#5630, #5599)
• We have added a @jupyterlab/ui-components package that contains reusable React components to be used internally and in extensions. Feel free to use this to create extension UIs with consistent styles (#5538)
• The showErrorMessage function now lets you customize the buttons it uses (#5513)
• We now provide helpers for using React components within JupyterLab. If you were previously using ReactElementWidget you should switch to using ReactWidget. (#5479, #5766, #6595, #6595)
• The share link command has been moved to its own extension so that it can be overridden (#5460, #5388)
• Creating a new services session now requires passing a kernel model instead of a kernel instance (#6503, #6142)
• We upgraded the Webpack raw file loader. The new version of the raw loader exports ES2015 modules, so this may require changes in extensions that import files using the raw loader. For example, if you did require('myfile.md') to get the content of myfile.md as a string, you now should import it using ES2015 import syntax, or use require(\'myfile.md\').default.
• Widget factories now can support custom cloning behavior from an optional source widget (#6060, #6044)
• We have renamed the type InstanceTracker to WidgetTracker (#6569).
• In order to add widgets to the main area (e.g. as in the old XKCD extension tutorial), the correct syntax is now app.shell.add(widget) or app.shell.add(widget, 'main'), see here.
