[26] Web Components は、 Web において文書中で利用できるウィジェットを定義し利用するための技術群です。

言語

[28] Web Components は次の技術で構成されています。

  • HTML Imports
  • 装飾器

[62] Chrome が最初に実装した後、他の Webブラウザー事業者と調整して改めて標準化されたため、 当初案のうち受け入れられなかった部分が色々と変更されています。 従って初期(10年代前半)とその後では互換性がありません。

[61] JavaScript ライブラリーの中には、 Web Components 対応と称して独自の機能を色々と盛り込んでいるものもあります。

歴史

[64] この分野では1990年代から HTC, Action Sheets, XBL1, svg:use, RCC, sXBL, XBL2 と様々な技術が提案されてきましたが、いずれも成功とはいい難い結果に終わっていました。 本分野が Web における未解決問題であるとの認識は Webブラウザー事業者界隈では広く共有されていましたが、 期待だけが高まった状態で長い年月が経過していました。

[27] Web Components は、 XBL2 が結局実装できなかった反省から、 いくつかの技術に分割して標準化と実装を順次進めていく形で開発が進められています。
