Heroku push failed React

发布于 2020-10-07 16:28:25

I am trying to deploy my create-react-app to heroku, I deployed my backends Nodejs express normally but now that I am done with my frontend React I try to push code and I get error. I tried to push over terminal following this code:

heroku create $APP_NAME --buildpack mars/create-react-app
git push heroku master
heroku open

And I tried to connect my github with heroku and I get same error. I use react-router-dom in my app, react icons and react hooks.

This is the error:

Read through the log. Especially the part below "Running build". It says: Error: Parse Error: <3 FOOD</title>. This means that you have a syntax error in your HTML, in your <title> tag. Since you're using CRA, it's most likely the public/index.html file.

The error suggests that you have <3 in your title. In HTML, you have to escape the < and > characters in text, as those reserved for HTML tags.

In your <title>, replace <3 with &lt;3. The &lt; is the HTML entity for the < character (less than).
