Disallow concatenation of formatMessage id (@deskpro/deskpro-product/no-concatenated-formatMessage-id)

We have a cleanup script that runs occassionally to remove unused translation keys from the language files (resources/language/messages). If you break up the translation key with concatenation, then the cleanup script won't find the translation key in the codebase and will remove it from the language files. Solution: if your translation key is dynamic then use a switch statement or ternary

Rule Details

This rule aims to prevent concatenation of translate id keys.

Examples of incorrect code for this rule:

intl.formatMessage(`agent.mass_actions.${entityType}.action`);
intl.formatMessage("agent.mass_actions" + entityType + ".action");

Examples of correct code for this rule:

intl.formatMessage({ id: entityType === "ticket" ? "agent.mass_actions.ticket.action" : "agent.mass_actions.articles.action" });
