concat's Issues

concat not working with dynamic values

Hi. I have an issue I would like to resolve. When I explicitly use a string:

concat([..], "path/to/destinatin");

..then the concat works. But when I:

let path = "path/to/destinatin";
concat([..], path);

..then the concat does not work. What am I possibly doing wrong?

Variations that do not work either:

let path = String("path/to/destinatin");
concat([..], path);

let path = "path/to/destinatin".toString();
concat([..], path);

await second method

how are we expected to await using this api method?

concat([file1, file2, file3], outputFile)

suggestion: detect location of node_modules

Sometimes I use concat to build my javascript project. And sometimes my projects use some modules from NPM. So I think it would be a good idea to detect the location from node_modules using require.resolve().

So instead of
concat ./node_modules/.../...js ./index.js
we could do
concat npm_module_name ./index.js

What do you think?

"The syntax of the command is incorrect" error

I get a "The syntax of the command is incorrect". any ideas what i am doing wrong?

Concat files in directory

Is it possible to concat all files in a directory?

Let's say I have a folder with 20 js files, I want to concat all of them but listing it individually in an npm script is rather tedious.

I tried "my_modules/js/*.js" which doesn't work - but it would be awesome if it did. In this case it would get all the files with .js extension in that folder.

assets

Hey
im new using this library and i have one issue
When i generate the concat file, it ignores de assets build folder and some of the functionalities are lost

can you help me how to avoid this lost?

No option for delimiter

Using this within a node application, I hit a case where I wanted to concatenate multiple files together without inserting a linebreak between them (it's for reassembling a single piece of data spread across files). Currently the newline is hard-coded. I fixed it in my local build by hacking the change into the package, but maybe it would be worthwhile including an option to either omit the \n or take it a step further by allowing the user to supply a delimiter string, much like the join method on an array. Obviously this would be an optional parameter with the default behavior being identical to current behavior.
To be clear, I don't mind doing the work and submitting a PR if I've got agreement on the change.

Promise resolves before file is finished writing

Hi, please change it so that the concat Promise doesn't resolve until the file saving is finished. When I load the combined file after then() is called, it sporadically causes an error because the file is not there yet. This package therefore cannot be used to reliable read the file after concatenation.

Tested on Mac in a Node Webpack build pipeline.

concat( [ part1.js, part2.js' ], combined.js ).then( resolve('While the combined result is available here in variable result, combined.js is not always finished being saved to disk.') )

Add folder support.

Hi,
Could you add support for folders ex:
concat -o output.css ./folder
It would make the package.json CLI scripts lines cleaner / easier to maintain.
