How to reset versions in Package.json

I have about 20 react projects, all of which have package.json files. I have packages like this in them:

"@material-ui/core": "4.11.4",
"@material-ui/icons": "4.11.2",
"@material-ui/lab": "4.0.0-alpha.58",
"@material-ui/styles": "4.11.4",

I need to go through every single one line and update them to “0.0.0”. Is there a regex that can match "***.***.***" and replace it with “0.0.0” ?

Reason why I need to do this: I create my own packages. I moved them from one location to another, so their versions started from 0 all over again. If I do npm check updates, and package is 5.8.34 for example, it won’t update it back to 0.0.1. But if I update all of their values to 0.0.0 then run npm check updates it’ll update to 0.0.1.

Also, why anyone would be voting -1 here? Don’t like the question or don’t know the answer? I provided all I need to accomplish here and Below are some Regex I attempted. Why would you still vote -1?

I tried: : "[0-9].+?"

So far this does the best job : "[0-9].[0-9].[0-9]"

It won’t find ones that have letters in package name such as "@material-ui/lab": "4.0.0-alpha.58". If anyone shares a better solution I’ll update the question.

This is purely a question how to reset versions of Packages in Package.json file to 0.0.0.

Answer

If all the packages start with a digit followed by a dot and word characters which can optionally have a hyphen in between the word characters, you can use a capture group and use that in the replacement.

Pattern:

("[^s"]+":s*")d+(?:.w+(?:-w+)*)+",

The pattern matches:

• ( Capture group 1 (denoted by $1 in the example code)
  • "[^s"]+":s*" Match from "..." then : and optional whitespace chars
• ) Close group 1
• d+ Match 1+ digits
• (?: Non capture group
  • .w+(?:-w+)* Match a . 1+ word chars and optionally - and 1+ word chars
• )+ Close the non capture group and repeat 1+ times
• ", Match a double quote and comma

Replace with

$10.0.0",

Regex demo

const regex = /("[^s"]+":s*")d+(?:.w+(?:-w+)*)+",/;
[
  `"@material-ui/core": "4.11.4",`,
  `"@material-ui/icons": "4.11.2",`,
  `"@material-ui/lab": "4.0.0-alpha.58",`,
  `"@material-ui/styles": "4.11.4",`
].forEach(s => console.log(s.replace(regex, `$10.0.0",`)));
