TextNode
The text node represents text where both the whole node or individual character ranges can have properties such as color (fills), font size, font name, etc.
When working with text nodes, there are a lot of things to consider:
- Mixed styles
- Loading fonts
- Missing fonts
Mixed styles
Many text properties can be set on individual characters. For that reason, you will find that many of text properties can return the special value figma.mixed if there are characters in the text with different values for that property. Always consider that a text properties could have mixed values.
Loading fonts
The important thing with text is that changing the content of a text node requires its font to be loaded and that fonts are not always available. If you attempt to change, say, fontSize without first loading the font for that text node, the plugin will throw an exception.
When setting the .fontName or .textStyleId property, you do only need to load the new font. When setting any other property that affects text layout, you need to load all the fonts that the text node already use. This includes the following properties and functions:
charactersfontSizefontNametextStyleIdtextCasetextDecorationletterSpacinglineHeightsetRangeFontSize()setRangeFontName()setRangeTextCase()setRangeTextDecoration()setRangeLetterSpacing()setRangeLineHeight()setRangeTextStyleId()
You do not need to load a font in order to change properties that only affects colors and strokes, such as .fills, .fillStyleId, .setRangeFills(), .strokes, .strokeWeight, .strokeAlign, .strokeStyleId, .dashPattern.
Loading a font is done via figma.loadFontAsync(fontname).
For text nodes that contain a single font, you can call figma.loadFontAsync(node.fontName). For nodes that contain multiple fonts you need to use the getRangeFontName API to get all the fonts that the node is using. As an example:
let len = node.characters.length
for (let i = 0; i < len; i++) {
await figma.loadFontAsync(node.getRangeFontName(i, i+1))
}
Missing fonts
You will also need to check text.hasMissingFont before loading a font. If your plugin works with text, do not to ignore this. While less frequent during testing, it's very common in the real world that your users will attempt to run your plugin in a file with missing fonts.
How text works in Figma (and why you need to load fonts)
When a user types into a text node or changes one of its properties, we generate a path to represent the text, and store it along with the text node. This way, sharing a file (e.g. to a client) allows them to see the design as-is. Even if they don't have the fonts installed on their system! However, this means that even when a text node looks fine, it may not be editable.
Furthermore, the font file is not always loaded in memory even when it is available. This is because font files can be big, there could be many of them, and aren't needed until the text is edited. This makes loading them at startup time potentially very expensive. As such, calling
loadFontAsyncis necessary to ensure that the font is available.
Text node properties
