Supporting l10n (Localization) in GatsbyJS (Using Functional Programming)
Key point
Introduces how to implement l10n functionality for multilingual support using GatsbyJS and fp-ts.
Details
Covers how to leverage the Gatsby API and React to support l10n (localization) in a GatsbyJS-based web application. Rather than simply providing translations, it focuses on implementing page routing and applying translations based on browser language settings.
To manage translation data, it utilizes the functional programming library fp-ts. Data is managed as ts files, and to maximize the benefits of Static Site Generation (SSG), the data contained in the files is generated as Gatsby GraphQL Nodes for use.
The main implementation steps are as follows:
- Use the
createSchemaCustomizationAPI to explicitly define the schema of the TranslationData node. - Convert file-based translation data into Gatsby nodes via the
sourceNodesAPI and thecreateNodefunction. - Use fp-ts's
pipeandmapto efficiently process data for multiple languages with a single piece of logic.
