Are one of the supported field types (string, text, or structured_text)\n2. Have length validation configured\n3. Don't already have the character counter addon installed\n\nThe counter displays the current character count in a small, unobtrusive format below the field.\n\n## Implementation\n\nBased on the official [DatoCMS character-counter plugin](https://github.com/datocms/plugins/tree/master/character-counter).\n",[154],"25042d44-c3b4-11f0-ae51-42dde27851f2","FieldExtension.tsx","25042e20-c3b4-11f0-ae51-42dde27851f2",12,["D",1763383893093],"/** @jsxImportSource https://esm.sh/react */\nimport type { RenderFieldExtensionCtx } from \"https://esm.sh/datocms-plugin-sdk\";\nimport { Canvas } from \"https://esm.sh/datocms-react-ui\";\nimport { get } from \"https://esm.sh/lodash-es\";\nimport {\n type Node,\n isText,\n} from \"https://esm.sh/datocms-structured-text-slate-utils\";\n\ntype Props = {\n ctx: RenderFieldExtensionCtx;\n};\n\nfunction visit(\n nodes: Node[],\n test: (x: Node) => x is X,\n callback: (node: X) => void\n): void {\n nodes.forEach((node) => {\n if (test(node)) {\n callback(node);\n }\n\n if (\"children\" in node) {\n visit(node.children as any as Node[], test, callback);\n }\n });\n}\n\nfunction getCharCount(value: unknown, fieldType: string) {\n if ([\"string\", \"text\"].includes(fieldType)) {\n return (value as null | string)?.length || 0;\n }\n\n if (fieldType === \"structured_text\") {\n if (!value) {\n return 0;\n }\n\n let counter = 0;\n\n visit(value as Node[], isText, (textNode) => {\n counter += textNode.text.length;\n });\n\n return counter;\n }\n\n throw new Error(\"This should not happen\");\n}\n\nexport default function FieldExtension({ ctx }: Props) {\n const charCount = getCharCount(\n get(ctx.formValues, ctx.fieldPath),\n ctx.field.attributes.field_type\n );\n\n const wrapperStyle = {\n fontSize: \"var(--font-size-s)\",\n color: \"var(--light-body-color)\",\n };\n\n return (\n
