WebStorm Live Templates for repeatable async boilerplate

Stop retyping the same async skeleton

Live templates are the practical way to turn a short abbreviation into a context-aware code block in WebStorm. The useful takeaway is to bind an abbreviation to a single language context, define the template text with explicit variables and a final cursor marker, and test the expansion in a throwaway file. That gives you reliable boilerplate without clashing with built-in completions.

Mechanism with one worked configuration

Templates live in Settings | Editor | Live Templates. Each template has an abbreviation, a template text with variables, and a context that restricts where it can expand, such as JavaScript, TypeScript, in a function declaration or at the top level.

Example configuration for a promise-returning async function skeleton:

• Abbreviation: pfs
• Template text:

async function $FUNCTION$($PARAMS$) {
  return $CODE$;
}$END$

• Variables: $FUNCTION$ prompts for a name, $PARAMS$ prompts for parameters, $CODE$ is the editable return body, $END$ places the caret after expansion.
• Context: JavaScript and TypeScript, applicable in expression and declaration contexts, not in comments or strings.

To create it, open Settings | Editor | Live Templates, select the JavaScript group or create a new group, click +, choose Live Template, set the abbreviation, paste the template text, click Define and check JavaScript and TypeScript. Click Edit variables to set default values or expression evaluation for $FUNCTION$.

Usage is abbreviation then Tab or Enter in a file matching the context. The IDE expands the text and steps through variables in order. $SELECTION$ can be used to wrap an existing selection, but it only makes sense in expression contexts.

Limits and common mistakes

Variable scope is limited. Some variables only evaluate in specific contexts. Using $SELECTION$ outside an expression context produces empty or broken expansions.

Abbreviation conflicts cause unexpected behavior. If the abbreviation matches a built-in completion or another plugin suggestion, expansion may not trigger or may trigger incorrectly. Choose short but uncommon abbreviations and test against the target language.

Missing $END$ leaves the caret in an invalid position. Always include $END$ or a final $caret$ marker so the workflow continues smoothly after expansion.

Performance degrades with hundreds of complex templates. Nested conditionals and large template bodies increase editor responsiveness cost on project open and completion.

Practical verification: create a temporary .ts file, type the abbreviation and expand, confirm variable prompts and final caret placement. Export templates via File | Manage IDE Settings | Export Settings and inspect the JSON to confirm persistence across reinstalls.
