The build script uses rollup to convert it to commonjs. The build script is located in /build/cjs.cjs. This package has a small build script which you can call. If you must use commonjs, then you can convert this package into cjs by using rollup. This package is smart and it will efficiently find matches spanning multiple chunks, and get rid of text it knows won't have a match. We need to be watching the first 'p' and the third 'p', because it could end up being 'paper', if the next chunk was 'er', or it could end of being 'papaper'. Let's say we get 'pap' in our first chunk. It gets even more complicated when multiple potential matches are possible. If we get something else, like 'ear', we can attach it to the 'p' and output 'pear'. If we get 'aper' in the next chunk, we replace the text. Since we aren't sure if the 'p' will be replaced or not, we hold on to this text, and check it once we get the next chunk. However, if our first chunk was: 'p', we can't pass that on, because there is a change that the next chunk could start with 'aper'. We can then pass the chunks onto the output of the transform stream, available right away for the stream consumer. If our first chunk was: 'perfect pot', this module knows that there is no way the string 'perfect pot' will fit into the search string, 'paper'. Let's say we were looking for 'paper' in our text. The tricky part with this transform stream is knowing when to hold chunks, and when to pass them on. In this particular transform stream, it takes a string and outputs the same string, except that it replaces the replace. Transform streams take in chunks and can also be read. The replace function returns a Node.js transform stream. See the How It Works section for more information. If your replaceWith stream is very large and you have a limit of 1, you can set this to false to save memory. For fastest performance, keep this to be true. If this is true, the replaceWith stream will be read right away, and be kept in memory to be used once a match is found. bufferReplaceStream (optional, default true) - This is for when you use a readable stream for replaceWith.Once this limit is reached, the transform stream will stop transforming anything. This can be useful if you know there is only 1 occurrence of searchStr. limit (optional, default Infinity) - The maximum number of strings to replace.options (optional) - An object of options.See options.bufferReplaceStream for options if you are using a readable stream. Readable stream - A readable stream can be given, which can make more chunks available sooner.This function should return a string or a promise resolving a string. The function can take a parameter, matches, which is the number of matches so far (for the first match, this will be 0). Replacer function - This is a custom replacer function.Promise resolving a string - Once the promise is resolved, the given string is used.replaceWith - There are a couple of different things you can use:.This must be a string, and cannot be a regex.
