Get number of rows in reference

I have two tables with one referencing the other one. Here is the code:

CREATE TABLE blogs (
    article LONGTEXT,
    id VARCHAR(255) PRIMARY KEY
);

CREATE TABLE blog_eval (
    blog_id VARCHAR(255) REFERENCES blogs(id) ON DELETE CASCADE,
    user_id VARCHAR(255) REFERENCES users(id),
    is_like BOOLEAN, --true if like / false if dislike
    PRIMARY KEY (blog_id, user_id)
);

I need to get all blogs with two additional columns: sum of likes and sum of dislikes.

I am not really sure how to combine a JOIN with the COUNT-Function and also add the logic to distinguish between likes and dislikes.

I am using MySQL.

Thanks for your help!
