TypeError: Cannot convert a Symbol value to a string

[fengxinming]

I am not sure if the Symbol value would be ignored

const { stringify } = require('query-string');

stringify({ a: () => (1), b: Symbol('test') });

module.exports = str => encodeURIComponent(str).replace(/[!'()*]/g, x => `%${x.charCodeAt(0).toString(16).toUpperCase()}`);
                        ^

These are the supported values: https://github.com/sindresorhus/query-string/blob/20992772758fc74188db64e789535469adaf241f/index.d.ts#L398-L403

I guess we could improve the readme to mention those too, and also throw a more human-friendly error.

@sindresorhus I feel like the Symbol value being ignored that would be better

[sindresorhus]

I disagree. That could hide bugs. I prefer strict type checking. This is also how the browser API works:

new URLSearchParams({foo: Symbol()})
//=> Uncaught TypeError: Cannot convert a Symbol value to a string

[fengxinming]

@sindresorhus but other packages like qs and querystringify work well if give a Symbol value.

[sindresorhus]

That is not a good argument for doing it.

[fengxinming]

@sindresorhus anyway, it's up to you

[RiteshKSingh1709]

@sindresorhus Yes you were right, Symbol should not be converted to string , from mdn web docs

We are having a similar issue encodeURIComponent(...).replaceAll is not a function in:

TypeError: encodeURIComponent(...).replaceAll is not a function

It's only happening to users on Edge 122. A very strange errror.

The code is:

  const search = queryString.stringify({
    'redirect-to': `${location.pathname}${location.search}`,
  });
