refurb-json-minify
A small plugin for Refurb aimed at minifying JSON outputs.
Why is this important?
JSON is a widely used format for data exchange, whether that be APIs talking over the internet, metadata being stored in a database, or config files stored on a user's filesystem. Although CPU and harddrive space is getting cheaper and cheaper, it isn't free, and being mindful of resources can lead to faster and more efficient programs.
Supported Checks
JMIN100: Use separators
The json.dump and
json.dumps functions
allow for an optional separators field which specifies what characters to use
for colons (:) and commas (,) in the JSON output. Normally there is whitespace
after these characters, but you can change this to use a more compact format.
Here is a simple example comparing the output of json.dumps() with and without
separators specified:
import json
data = {
"hello": "world",
"numbers": [1, 2, 3, 4],
}
a = json.dumps(data)
b = json.dumps(data, separators=(",", ":"))
print(f"{len(a)=}", f"{len(b)=}")
When we run this, we get:
len(a)=43 len(b)=37
By reducing the whitespace in our JSON output we where able to shave off 6 bytes, or about 16% in this example.
JMIN101: Don't json.dump() integers
Don't call json.dump() on integers, use str() instead since they share the
same representation.
