v0.4.2

Added

• Import maps are now supported. This allows customizing the URL that a bare
  module specifier resolves to, e.g. to a specific version, or to a different
  CDN.

  Note that import maps currently only apply to the immediate imports of
  project source files, not to external transitive dependencies.

  Also note scopes are not yet supported, only imports.

  See https://github.com/WICG/import-maps and
  https://wicg.github.io/import-maps/ for more information on import maps.

  Previously, all bare modules resolved to unpkg.com URLs at the latest version.
  This continues to be the fallback behavior if no import map is provided, or no
  entry in it matches.

  To specify an import map in a JSON project manifest, add an importMap
  property:

  {
    "files": {
      "index.html": {},
      "my-element.ts": {}
    },
    "importMap": {
      "imports": {
        "lit-html": "https://unpkg.com/lit-html@next-major",
        "lit-html/": "https://unpkg.com/lit-html@next-major/"
      }
    }
  }

  To specify an import map inline, add a <script type="sample/importmap">
  slotted child:

  <playground-ide>
    <script type="sample/importmap">
      {
        "imports": {
          "lit-html": "https://unpkg.com/lit-html@next-major",
          "lit-html/": "https://unpkg.com/lit-html@next-major/"
        }
      }
    </script>
    ...
  </playground-ide>

Fixed

• Bare module imports in .js files are now resolved in the same way as .ts
  files.

v0.4.1

Fixed

• Fixed <playground-file-editor> not always displaying initial file.
• Fixed editable-file-system attribute name (was editableFileSystem).
• Fixed <playground-ide> not stretching <playground-file-editor> vertically.

v0.4.0

Added

• Added editableFileSystem property (editable-file-system attribute) to
  <playground-ide>. When true, the user will be able to create, delete, and
  rename files in the virtual filesystem.

  • To create a new file: click the "+" icon button in the tab bar.
  • To rename a file: click the three-dots menu button on its tab, and select
    "Rename".
  • To delete a file: click the three-dots menu button on its tab, and select
    "Delete".

• Added <playground-file-system-controls> element which displays popup
  menus/dialogs for creating, deleting, and renaming files.

Changed

• [BREAKING] The tab bar has been factored into a new standalone element
  called <playground-tab-bar>. The <playground-file-editor> element no
  longer integrates the tab bar, and the noFilePicker property has been
  removed.

• [BREAKING] The following CSS custom properties have been renamed:

  • --playground-file-picker-background -> --playground-tab-bar-background
  • --playground-file-picker-foreground -> --playground-tab-bar-foreground

• [BREAKING] The following CSS shadow parts have been renamed:

  • file-picker -> tab-bar

v0.3.7

Added

• Added files property to <playground-ide> and <playground-project>. Use
  this property to directly get and set the array of project files (e.g. to
  save/restore the project state).

  Note that directly setting files always takes precedence over setting
  projectSrc, and both take precedence over slotted children.

Changed

• It is no longer necessary to load the Material Icons font. The reload button
  icon is now inlined SVG.

Fixed

• Fix caret placement issues with some dynamic layouts.

v0.3.6

Fixed

• Fix shifted/hidden code in Safari when line numbers are enabled.

v0.3.5

Fixed

• Fix mwc-tab race condition bug (dependency version bump).

v0.3.4

Changed

• The playground service worker now serves its own 404s when a file is not
  found, instead of forwarding the request to the server.

Fixed

• Fix race condition where preview could load too early and 404.
• Fix race condition where preview could sometimes never load.
• Fix preview 404 that could occur after leaving page idle for some time.

v0.3.3

Fixed

• Fix Safari scrolling bug by limiting preview max-height.

v0.3.2

Fixed

• Fix installation error relating to missing node_modules/puppeteer directory.

Changed

• Bumped and un-pinned @material/mwc dependencies.

Removed

• Removed some unnecessary files from NPM package.

v0.3.1

Fixed

• Remove debugging log statement.
• Remove unecessary file from NPM package.
