Webpack loader for replacing a text and other data in a file

Instalation:

``
npm install --save-dev replace-string-loader
`

Options:

`
options: {
search: "string or /regExp/",
replace: "string or function",
flags: "string",
file: bool
}
search: a string or a regular expression that will be found and replaced in the file.
replace: a string or a function for replacing.
If an options.replace is a function: this function recieves next arguments:
match – a found match,
p1, p2, ..., pn – string content (if exist),
offset – position where the match was found,
s – a basic string.
The function must return a string!!!
flags: regExp flags (g, i, m). Used if options.search is a string and ignored if options.search is a regular expression.
file: if true - a found result will save to the file.
`

Usage:

Searching and replacing '105px' to '200px' in scss files:
Result will be saved to a json file.
`
module: {
rules: [{
test: /\.scss$/,
use[{
loader: 'replace-string-loader',
options: {
search: '105px',
replace: '200px',
flags: 'g',
file: true
}
}]
}]
}
`
An output json file:
`
{
"file": "[last-file-folder][file-name].[ext]",
"fullFilePath": "full-path-to-file/[file-name].[ext]",
"matches": [
{
"matchLine": 12,
"matchContent": "min-height: 105px;",
"replaceTo": "min-height: 200px;"
},
{
"matchLine": 22,
"matchContent": "min-height: 105px;",
"replaceTo": "min-height: 200px;"
}
]
}
`
or, without saving into the file
`
module: {
rules: [{
test: /\.scss$/,
use[{
loader: 'replace-string-loader',
options: {
search: /105px/g,
replace: '200px',
