How to match from start and end and, replace string in javascript
1
I want to change a string/line of a file main.js from another file replace.js
I want to change the server property dynamically based on machine ip
main.js
export const environment = {
production: false,
server: `http://localhost:3000`,
apikey: `X199`
};
replace.js
const replace = require('replace-in-file')
const address = require('address')
replace({
files: 'main.js',
from: /^server:..*3000,$/g,
to: `http://${address.ip()}:3000`
})
I have tested multiple regex but none was working for me.

Not sure but if you want to matchserver: `http://localhost:3000`,you have to remove matching the literal dot and add a`after 3000 like^server:.*3000`,$see regex101.com/r/WJkRY6/1

@Thefourthbird as per your recommended site, regex is working fine but not inreplace-in-filenpm package that I am using

Did you try it without the anchors?/server:..*3000,/gor match leading whitespace characters/^s*server:..*3000,$/g

Try using
replace({
files: 'main.js',
from: /server:s*[`'"]https?://.*?[`'"],/g,
to: `server: 'http://${address.ip()}:3000',`
})
The anchor tags ^$ is not needed because the string 'server: http://localhost:3000' is not started at the very beginning of the file, and is not ended at the very end of the file.

Try using
replace({
files: 'main.js',
from: /server:s*[`'"]https?://.*?[`'"],/g,
to: `server: 'http://${address.ip()}:3000',`
})
The anchor tags ^$ is not needed because the string 'server: http://localhost:3000' is not started at the very beginning of the file, and is not ended at the very end of the file.
