go-multilang-api

Description

A simple API that demonstrates how to manage multiple languages in your service. The project also shows how to deal with pluralization.

Built using gotext.

There are two supported languages in the repo: en-US, fr-FR.

Prerequisites

Make sure that gotext is installed:

go install golang.org/x/text/cmd/gotext@latest

How-to

To run service using default port 8080:

make run

Make a request using different languages

curl -H "Accept-Language: en-US" localhost:8080
curl -H "Accept-Language: fr-FR" localhost:8080

Workflow

A typical workflow when working with gotext:

Do not edit automatically generated out.gotext.json files. All changes should be made in messages.gotext.json (make a copy from out.gotext.json if it's missing).

• Extract new strings from project to translate: make gen
• Edit internal/translation/locales to add translations.
• make gen to re-build message catalog (internal/translation/catalog.go).

When new languages need to be added:

• Add a new language in translation pkg: internal/translation/generate.go
• Extract the new language strings from project to translate: make gen
• Create messages to translate by copying output from the prev step (de-DE as an example):

    cp internal/translation/locales/de-DE/out.gotext.json internal/translation/locales/de-DE/messages.gotext.json
  

• Edit internal/translation/locales to add translations.
• make gen to re-build message catalog (internal/translation/catalog.go).
