kandi X-RAY | sucrase Summary

sucrase is a TypeScript library typically used in User Interface, Frontend Framework, React applications. sucrase has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Sucrase is an alternative to Babel that allows super-fast development builds. Instead of compiling a large range of JS features to be able to work in Internet Explorer, Sucrase assumes that you're developing with a recent browser or recent Node.js version, so it focuses on compiling non-standard language extensions: JSX, TypeScript, and Flow. Because of this smaller scope, Sucrase can get away with an architecture that is much more performant but less extensible and maintainable. Sucrase's parser is forked from Babel's parser (so Sucrase is indebted to Babel and wouldn't be possible without it) and trims it down to a focused subset of what Babel solves. If it fits your use case, hopefully Sucrase can speed up your development experience!. Sucrase has been extensively tested. It can successfully build the Benchling frontend code, Babel, React, TSLint, Apollo client, and decaffeinate with all tests passing, about 1 million lines of code total.

Why is Jest not inferring tests coverage lines correctly?

Asked 2021-Aug-07 at 20:53

I am not getting 100% of coverage for the file below and I cannot figure out why this is happening....

Focus of the question: understand why Jest is not considering my tests that cover the lines that Jest complains about not being covered.

Jest complains about these lines of code: 26-27,33-34,38-39,45-46, but these lines are covered, as it can be seen on the test file that I will paste below the production file.

26-27:

I think the problem is that your package.json says you are using ES6 modules, but your Babel config is using module.exports which is CommonJS (not ES6 modules).

I renamed my babel.config.js to babel.config.cjs and this fixed the problem. I guess you could also change module.exports to export default but I haven't tried this.

Why does my import statement have a syntax error in Deno but works ok in Nodejs?

Asked 2020-Jul-03 at 15:41

I'm testing with two VSCode setups; one running Deno, the other running Nodejs using the Sucrase compiler to transform the code so that I can write native ES6 modules. I have a very simple test: a small Class and a module that imports it. Here is the Deno VSCode setup.

My VSCode explorer panel looks like this.

Instead of importing module inside function move outside like this. If you want to load module lazyly use dynamic import

Try this:

EC2 AWS 405 (Not Allowed) and CORS problems with NGINX FrontEnd && BackEND

Asked 2020-Jun-20 at 07:11

I have a front-end app with reactjs and back-end with express where locally i send the front-end data by using localhost:3333 with axios, got no problem with that.

Now i'm trying to use an EC2 AWS instance to host this application but got no success.

The ec2 instance is only for tests, so it public DNS IPV4 is: http://ec2-18-228-222-138.sa-east-1.compute.amazonaws.com/ and public IPV4 is: 18.228.222.138

When i try to POST method into server acessing the public DNS, i get a message from console browser saying: Access to XMLHttpRequest at 'http://18.228.222.138/uploadFile' from origin 'http://ec2-18-228-222-138.sa-east-1.compute.amazonaws.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

When i try to POST by public IPV4 (18.228.222.138) i get from console browser: 405 (Not Allowed).

I can't figure out what i'm missing where.

My codes and configs:

Running back-end on port 3333 with npm start or pm2 start npm -- run server. Index.js code:

That 405 makes it seem more like an issue with POST not being allowed by your web server.

You need to import your model before you use it so require your model first in app.js as you imported campground model
