defaultIconPack

Name of a registered iconify pack used to resolve unprefixed icon references — icon(name) annotations and filenameIcons/ extensionIcons values without a pack: prefix. The pack must be registered with registerIconPacks. When empty, unprefixed names resolve to the built-in file/folder icons.

defaultIconPack

• is optional

• Type: string

• cannot be null

• defined in: Mermaid Config

defaultIconPack Type

string

defaultIconPack Default Value

The default value is:

""

filenameIcons

Exact-filename → icon map used to pick a file's icon when showIcons is enabled, e.g. { "Dockerfile": "material-icon-theme:docker" }. Values are resolved like icon() references: pack:name is used as-is, unprefixed names resolve via defaultIconPack, and none hides the icon for matching files.

filenameIcons

• is optional

• Type: object (Details)

• cannot be null

• defined in: Mermaid Config

filenameIcons Type

object (Details)

filenameIcons Default Value

The default value is:

{}

extensionIcons

File-extension → icon map used to pick a file's icon when showIcons is enabled, e.g. { ".ts": "material-icon-theme:typescript" }. Keys are lowercase and may include or omit the leading dot. Values are resolved like icon() references: pack:name is used as-is, unprefixed names resolve via defaultIconPack, and none hides the icon for matching files.

extensionIcons

• is optional

• Type: object (Details)

• cannot be null

• defined in: Mermaid Config

extensionIcons Type

object (Details)

extensionIcons Default Value

The default value is:

{}
