What is the process of using 'DefaultImports' to import DTOs into TypeScript through ServiceStack?

Whenever I attempt to utilize the command line tools that come with ServiceStack for TypeScript, I continuously encounter issues with the DefaultImports functionality not behaving as anticipated or being particularly beneficial. What is the proper way to make use of this feature?

For instance:

/* Options:
Date: 2019-02-08...

...
//ExcludeTypes: 
DefaultImports: Example
*/

Results in

import Example;

This does not align with my expectations, as I am expecting something like

import Example from ExampleModule
. Am I missing a crucial detail, or is my interpretation flawed?

DefaultImports: Example from ExampleModule
gives me the messy import ExamplefromExampleModule;. Using quotes does not seem to resolve the issue either.

Answer №1

Check out these examples of different DefaultTypes imports that are currently popular:

  • DefaultTypes: 'es6-shim' -> import 'es6-shim';
  • DefaultImports: './my-module.js' -> import './my-module.js';
  • DefaultImports: $ from 'JQuery' -> import $ from 'JQuery';
  • DefaultImports: * as Zip from "./ZipCodeValidator" ->
    import * as Zip from './ZipCodeValidator';

Additionally, I've added support for the concise Symbol:module import. Here is an example of the output:

import { Symbol } from "module";

This enhancement is included in version v5.4.1, now accessible via MyGet.

If you are experiencing issues, I suggest updating the tools you use to fetch dtos to the latest version.

npm tools

To upgrade using @servicestack/cli npm tooling, uninstall and reinstall as follows:

$ npm uninstall @servicestack/cli
$ npm i -g @servicestack/cli

Ensure you are using at least v1.0.7 by checking the version:

$ typescript-ref -v

Version: 1.0.7

To update any *dtos.ts in your directory, run the tool without arguments:

$ typescript-ref

Testing with DTOs (using latest ServiceStack v5.4.1 on MyGet) is successful with the new Symbol:Module syntax:

/* Options:
...
DefaultImports: Zip:./ZipCodeValidator
*/

This generates the expected import:

import { Zip } from "./ZipCodeValidator";

The import you're trying also works:

/* Options:
...
DefaultImports: * as Zip from './ZipCodeValidator'
*/

Which generates the expected:

import * as Zip from './ZipCodeValidator';

If the issue persists, consider upgrading the ServiceStack version of the API you're generating DTOs from.

Ensure tool functionality by generating DTOs from , which uses the latest version of ServiceStack:

$ typescript-ref https://techstacks.io

dotnet tools

Alternatively, use the @servicestack/cli npm tool or the web or app tool with these steps:

$ dotnet tool install -g web

Update it with:

$ dotnet tool update -g web

Check if you're using the latest 0.0.16 version:

$ web -v

Version: 0.0.16

Substitute web ts for typescript-ref (or ts-ref) npm tools, e.g. to install DTOs:

$ web ts https://techstacks.io

To update DTOs:

$ web ts
