VisualizaçõesExtracting `<key>:<value>` pairs with regex
there is a textarea and want to extract with key:value (something like below image)
I have a regex but not working as expected
/([^\s][a-zA-Z!]+:(\s)?"?([a-z0-9\s.]+)"?[^ $])/gi
if the user enters the below string at that time regex break the group key:value.
is:"browser" browser: "chrome 11.11 V" node: error type:"Error"
expected group:
is:"browser"
browser: "chrome 11.11 V"
node: error
type:"Error"

You can use
const text = 'is:"browser" browser: "chrome 11.11 V" node: error type:"Error"';
const re = /(\w+):\s*(?:"([^"]*)"|(\S+))/g;
let dict = {}, m;
while(m = re.exec(text)) {
dict[m[1]]=(m[3] || m[2]);
}
console.log(dict);
// Or just get all matches:
console.log(text.match(re))See the regex demo. Details:
(\w+)- Group 1: one or more word chars:- a colon\s*- zero or more whitespaces(?:"([^"]*)"|(\S+))- either of"([^"]*)"-", 0+ non-commas (captured in Group 2),"|- or(\S+)- Group 3: one or more non-whitespaces chars.
