Unexpected token when running example about nfc-pcsc HOT 8 CLOSED

Hi @emond07,

thank you for posting your issue. 🙂

According to the error output you posted, you are trying to run the basic example, right?

However, the examples use import/export modules syntax which is not supported in Node.js by default (you need some transpiler, e.g. Babel with appopripate plugins, or you can enable native support (with some limitations) in the newest Node.js versions).

The simplest way to run the example is with npm run example-basic or yarn example-basic. As you can see here in the package.json, it is actually an alias for node -r babel-register examples/basic.js. Requiring babel-register using -r flag, ensures the code is transpiled applying rules from project's root .babelrc.

Hope it helps.

Feel free to contact me, if you encounter any problems or need any help.

PS Don't forget to star ⭐️ my library, if you find it useful. 😃 Thanks.

Hi @emond07,

it seems that you had not installed the dependencies before you ran the example.

Try to install the dependencies with npm install first and then run npm run example-basic.

For more info, see Running examples locally section of the README.

Hope it helps. 🙂
