# Hide file from git diff output

`git diff` will show patches for text files, but not for binary files, like images, because the output is not likely to make any sense. Some checked in text files, like `package-lock.json`, can be considered binary too: while technically composed of text characters, it's opaque to a human reader. In addition to that, it's diff output long, and commonly fills the entire screen when running `git diff`. To avoid this, we can mark the file as binary by unsetting the diff attribute in `.gitattributes`:

```
package-lock.json -diff
```
