Code Templates in TypeScript

Most of ReSharper's code template features are also supported in TypeScript. You can find the detailed information on these features in the corresponding topics of the Code Templates section.

In this topic:

Live Templates

Live/Surround templates can be used for generating code in existing files and (if there is the $SELECTION$ parameter in the template body) for surrounding code fragments with template code, such as try...catch statement. Each live template is identified by a Shortcut - a short string of characters, e.g. foreach - that you can type right in the editor to invoke the template.

ReSharper provides plenty of predefined live templates. You can also create custom live templates in the dedicated editor or right from existing source code .

File Templates

File templates are used to create one or more new files with predefined code, such as a type declaration, unit test, etc. File templates have no shortcuts, they are identified by their descriptions. See Creating Files from Templates and Creating Multi-File Templates for details.

A file template can create more than one file when you apply the template. This may be helpful when related data is saved in different files.

There are predefined templates for file, class, interface, and module. You can also create new file and multi-file templates.

Postfix Templates

Postfix templates help you transform expressions that you have already typed without jumping backwards - just type a dot after an expression and pick a template from the completion list.

Below is the list of postfix templates available in TypeScript.

.else Checks boolean expression to be 'false' if (!expr)
.forof Iterates over an iterable object for (let x of expr)
.if Checks boolean expression to be 'true' if (expr)
.instanceof Checks instance of expression if (x instanceof Class)
.notnull Checks expression to be not-null if (expr !== null)
.notundefined Checks expression to be not-undefined if (expr !== undefined)
.null Checks expression to be null if (expr === null)
.return Returns expression from current function return expr;
.typeof Checks type of expression if (typeof x === 'string')
.undefined Checks expression to be undefined if (expr === undefined)
.var Introduces variable for expression let x = expr;
