tgz-modify
modify .tgz file entries:
Open ./files/package.tgz
.
make some changes to package/package.json
and remove README.md
all together.
Then output to a new .tgz file: ./output/package.tgz
const tgz_modify = require('tgz-modify')
tgz_modify('files/package.tgz', 'output/package.tgz', (header, data) => {
switch(header.name) {
case 'package/package.json':
let obj = JSON.parse(data)
obj.name = 'some-other-project'
obj.author = 'Some Jerk'
data = JSON.stringify(obj, null, '\t')
break;
case 'package/README.md':
return null // returning null will skip the file.
}
return data
})
To overwrite the .tgz file, simply use the same filename for the output file:
tgz.modify('./input.tgz', './input.tgz', ...)
