はじめに

vivus.jsという素晴らしい、プラグイン？を使用したのでメモとして残します。
まだ理解し切ってないので、本当にメモ書き程度のまとめです。

完成イメージ

手順

illustratorで新規作成

・「base」「mask」のレイヤー作成

・「base」レイヤーに文字を書く

・文字のオブジェクトの上で「右クリック」→「アウトラインを作成」

・そのまま(選択した状態で)「オブジェクト」→「複合パス」→「作成」

・「base」にロックをかけ、「mask」レイヤーに切り替える

・「ペンツール」で文字をなぞる
※この時、線どうしは被らない様にすると綺麗なアニメーションになる。交差点がある場合は、一旦線を切ってパスギリギリの幅の線を書くといい。

【ペンツールの使用前後の画面】

・最後にSVGに書き出す。

コーディング

・SVGをエディターで開く
※開いたら、タグ毎に改行すると見やすい

以下雛形をコピペし「３項目」元データのSVGから情報を採取する。
・viewBox=""はコピペ
・<g id="mask">~~~</g>はカット＆ペースト
・xlink:hrefはSVGファイルまでのURIを入力

雛形

<svg xmlns="http://www.w3.org/2000/svg" viewBox="コピペでOK" class="mask" id="move">
    <defs>
        <mask id="clipmask">
            <!-- <g id="mask">~~~</g> をカット&ペースト -->
        </mask>
    </defs>
    <image xlink:href="SVGファイルのURIを入力" width="100%" height="100%" mask="url(#clipMask)"></image>
</svg>

・SVGファイルの<style></style>に書かれている.cls-1{~~~}以外の部分をカット
・CSSファイルにペースト
・strokeのプロパティを#fffに変更

css(見やすいよう改行してます)

.cls-2,.cls-3,.cls-4,.cls-5,.cls-6,.cls-7,.cls-8{
    fill:none;
    stroke:#fff;
    stroke-linecap:round;
    stroke-miterlimit:10;
}
.cls-2{
    stroke-width:15px;
}
.cls-3{
    stroke-width:14px;
}
.cls-4{
    stroke-width:8px;
}
.cls-5{
    stroke-width:13px;
}.cls-6{
    stroke-width:5px;
}
.cls-7{
    stroke-width:17px;
}
.cls-8{
    stroke-width:6px;
}

・CDNを読み込み、JSをコピペ

html

<!-- Vivus JS CDN -->
<script src="https://cdn.jsdelivr.net/npm/vivus@latest/dist/vivus.min.js"></script>
<!-- Original JS -->
<script src="./js/main.js"></script>

js

new Vivus('move', {type: 'oneByOne',duration: 100,forceRender: false, animTimingFunction:Vivus.EASE_OUT})

おそらくこれで動くはず。
