typescript is a JavaScript library typically used in Server, Runtime Evironment, Nodejs, Jest applications. typescript has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can install using 'npm i @ava/typescript' or download it from GitHub, npm.

Adds TypeScript support to AVA. This is designed to work for projects that precompile TypeScript. It allows AVA to load the compiled JavaScript, while configuring AVA to treat the TypeScript files as test files. In other words, say you have a test file at src/test.ts. You've configured TypeScript to output to build/. Using @ava/typescript you can run the test using npx ava src/test.ts.

            React 18 TypeScript children FC
            Asked 2022-Apr-09 at 23:47

            I upgraded to React 18 and things compiled fine. Today it seems every single component that uses children is throwing an error. Property 'children' does not exist on type 'IPageProps'.

            Before children props were automatically included in the FC interface. Now it seems I have to manually add children: ReactNode. What is the correct typescript type for react children?

            Is this part of the React 18 update, or is something screwed up in my env?




            Answered 2022-Apr-07 at 20:34

            It looks like the children attribute on the typescript typings were removed.

            I had to manually add children to my props; There is probably a better solution to fix this, but in the interim, this works.

            AngularFire 7.0.0 was launched yesterday with a new API that has a lot of bundle size reduction benefits.

            Instead of top level classes like AngularFireDatabase, you can now import smaller independent functions.

            Your issue is related to interoperability between TypeScript/ECMAScript modules and CommonJS.

            When it comes to the differences between ECMAScript modules and CommonJS modules:

            • CommonJS modules are meant to be imported like const library = require('library') which allows to retrieve the full exports object of that library. There is no notion of default import in CommonJS
            • ECMAScript modules have explicit export clauses for every exported item. They also feature a default import syntax which allows to retrieve the default export in a local variable.

            In order to implement interoperability between CommonJS modules and TypeScript's default import syntax, CommonJS modules can have a default property.

            That default property can even be added automatically by TypeScript when esModuleInterop is enabled (which also enables allowSyntheticDefaultImports). This option adds this helper function at transpilation time:

            The unauthenticated git protocol on port 9418 is no longer supported
            Asked 2022-Mar-27 at 13:23

            I have been using github actions for quite sometime but today my deployments started failing. Below is the error from github action logs

            First, this error message is indeed expected on Jan. 11th, 2022.
            See "Improving Git protocol security on GitHub".

            January 11, 2022 Final brownout.

            This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
            This will help clients discover any lingering use of older keys or old URLs.

            Second, check your package.json dependencies for any git:// URL, as in this example, fixed in this PR.

            As noted by Jörg W Mittag:

            There was a 4-month warning.
            The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.

            Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".

            Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.

            The permanent shutdown is not until March 15th.

            In JavaScript/TypeScript you can throw anything, not only errors. In theory it could be anything in the catch block. If you want to prevent the type error it could make sense to check if the unknown value is a system error before checking the code.

            Answered 2022-Mar-15 at 16:08

            I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.

            So, do this:

            • In package.json, update the line "babel-eslint": "^10.0.2", to "@babel/eslint-parser": "^7.5.4",. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3.
            • Run npm i from a terminal/command prompt in the folder
            • In .eslintrc, update the parser line "parser": "babel-eslint", to "parser": "@babel/eslint-parser",
            • In .eslintrc, add "requireConfigFile": false, to the parserOptions section (underneath "ecmaVersion": 8,) (I needed this or babel was looking for config files I don't have)
            • Run the command to lint a file

            Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.
