Did you know? How to prevent duplicate placeholder strings in Transifex Live

Tips and Tricks

When working with dynamic values in input placeholders, it’s easy to unintentionally create dozens of duplicate strings in Transifex Live.

Let’s look at a common example.

The Problem

Consider an input placeholder rendered like this:

Choose a value up to 50

Later, the same input changes dynamically:

Choose a value up to 100

Choose a value up to 250

From a user perspective, this is clearly the same message with a changing number.
However, from Transifex Live’s perspective, these are three completely different strings.

  • Choose a value up to 50
  • Choose a value up to 100
  • Choose a value up to 250

As a result :

  • Each variation is detected separately
  • Each requires approval
  • Each requires translation
  • Your string list grows unnecessarily

That article focuses on localizing dynamic data values, while this post focuses on a Live detection edge case involving input placeholders.

The key idea

For placeholders, the goal is to ensure Transifex Live detects only the static part of the text, while the dynamic value is appended after translation, at runtime.

Recommended workaround for Live projects

  1. Define the static placeholder text

    const staticText = "Choose a value up to";

  2. Translate only the static text with Transifex Live

    const translatedText = Transifex.live.translateText(staticText);

  3. Append the dynamic value at runtime

    const placeholder = `${translatedText} ${dynamicValue}`;
input.setAttribute("placeholder", placeholder);

With this approach:

  • Transifex Live detects only:
    • Choose a value up to
  • You approve a single translation
  • All numeric variations are handled dynamically
  • No duplicate placeholder strings are created

Important note

If the full placeholder string (static + dynamic) is rendered before Transifex Live runs, Live may still detect it as a separate string.
To avoid this, make sure the translated text is explicitly applied at runtime.

When to use this

This workaround is especially useful for:

  • Input placeholders with limits or ranges
  • UI text with dynamic thresholds
  • Transifex Live projects where placeholders vary only by runtime values
