I got issues after adding flow

[markandersonus]

got a lot of issues on section 2 after adding flow.

also dog.js changed from

module.exports = Dog

to

export default Dog

is that correct

[markandersonus]

added to my .flowconfig

[ignore]
./node_modules/eslint-plugin-jsx-a11y/

now just getting:

5: const toby = new Dog('Toby')
^^^^^^^^^^^^^^^ constructor call. Constructor cannot be called on
5: const toby = new Dog('Toby')
^^^ CommonJS exports of "./dog"

[markandersonus]

changing dog.js back to...

module.exports = Dog

seems to fix it. is it a problem with the part two under: "Add Flow annotations to src/dog.js like so:"

[slifty]

Just wanted to note that I had the same set of issues as @markandersonus although his proposed fixes didn't solve it in my case. For now I'm just going to remove flow from the test script.

I'm seeing the same issues as @slifty - similarly the changes @markandersonus suggests do not fix for me.

[qwoz]

Looks to be related to this issue -- the solution for me was similar to the above-suggested .flowconfig addition:

[ignore]
.*/node_modules/eslint-plugin-jsx-a11y

[Laurian]

I'm using this, found it once somewhere online after a long night of things not working:

[ignore]
<PROJECT_ROOT>/node_modules/.*

[artemkovalyov]

My ignore looks like this and works well for me:
[ignore] .*/node_modules/eslint-plugin-jsx-a11y/.*

Same issue here @qwoz ignore works perfectly in my case

Had same issue, @qwoz's solution worked
