Ionic 2 Native File: Create directory recursively

Question

I am using Ionic 2 Cordova Plugin File to save some files in a Ionic Hybrid app. I would like to store them in directories, which, if not already existing, I try to create with:

this.file.createDir(this.getPathWithoutLast(absolutePath), this.getLastPathString(absolutePath), true);

My absolute path looks like this:

file:///data/user/0/io.ionic.starter/files/dir1/dir2/dir3/dir4

I get the error {"code":1,"message":"NOT_FOUND_ERR"}.

After some testing, I think that the method cannot create directories recursively, so I implemented my own method for creating them one after the other.

However, this seems like something that more people need so I would like to ask if there really is no such option in the Plugin and if not, whether there is a reason I did not think of.

Thanks everyone for their time! Pavol

I am going to post my solution as well, just in case:

    public async makeSureDirectoryExists(relDirPath: string): Promise<boolean> {
        console.log(`making sure rel Path: ${relDirPath}`);
        const absolutePath = this.file.dataDirectory + relDirPath;
        console.log(`making sure abs Path: ${absolutePath}`);
        const pathParts = relDirPath.split('/');

        const doesWholePathExist: boolean = await this.doesExist(absolutePath);
        if (doesWholePathExist) {
            return true;
        }
        let currentPath = this.file.dataDirectory;
        while (pathParts.length > 0) {
            const currentDir = pathParts.shift();
            const doesExist: boolean = await this.doesExist(currentPath + currentDir);
            if (!doesExist) {
                console.log(`creating: currentPath: ${currentPath} currentDir: ${currentDir}`);
                const dirEntry: DirectoryEntry = await this.file.createDir(currentPath, currentDir, false);
                if (!dirEntry) {
                    console.error('not created!');
                    return false;
                }
            }
            currentPath = currentPath + currentDir + '/';
        }
        return true;
    }
