Dirs.DocumentDir returning path but not storing files into it.

[vatsalkgor]

Hi I am trying to log some events that my app performs and then email it to concerned person. Below is my code snippet.

let current = new Date();
                RNFetchBlob.fs
                    .writeStream(
                        RNFetchBlob.fs.dirs.DownloadDir +
                            "/" +
                            current +
                            ".txt",
                        "utf8",
                        false
                    )
                    .then(stream => {
                        logsArray.forEach((sentence, index) => {
                            stream.write(sentence + "\r\n");
                        });
                        return stream;
                    })
                    .then(stream => {
                        return stream.close();
                    })
                    .then(() => {
                        logsArray = [];
                        Mailer.mail(
                            {
                                subject:
                                    "TEST EMAIL",
                                recipients: ["email@email.com"],
                                body:
                                    "Hi! I need support for my device. Can you please help? I have attached the logs from the app below.",
                                isHTML: false,
                                attachment: {
                                    path:
                                        RNFetchBlob.fs.dirs.DocumentDir +
                                        "/" +
                                        current +
                                        ".txt",
                                    type: "txt"
                                }
                            },
                            (error, event) => {
                                console.log(error), console.log(event);
                            }
                        );
                    })
                    .catch(err => {
                        console.log(err);
                    });

The problem is if i use the DownloadDir, the file is saved into the download directory in android (DownloadDir not supported in ios). But if I use DocumentDir then the file is not saved in android (not checked in ios)and there's no error occurred as well. I was wondering where I went wrong and wanted some feedbacks. I also want to ask does DocumentDir only works for ios or does it supports android also.

RN VERSION: 0.61.5 rn-fetch-blob: 0.11.2

Same Problem here :(

Hi @mohsenzia

I ended up doing the following:

let date = new Date();
const dir =
    Platform.OS === "ios"
        ? RNFetchBlob.fs.dirs.DocumentDir + "/" + date + ".txt"
        : RNFetchBlob.fs.dirs.DownloadDir + "/" + date + ".txt";
RNFetchBlob.fs
    .writeStream(
        //Not Sure if DownloadDir works on iOS
        dir,
        "utf8",
        false
    ).then(stream => {
        logsArray.forEach((sentence, index) => {
            stream.write(sentence + "\r\n");
        });
        stream.close();
        return stream;
    })
    .then(() => {
        const path =
            Platform.OS === "ios"
                ? RNFetchBlob.fs.dirs.DocumentDir +
                  "/" +
                  date +
                  ".txt"
                : RNFetchBlob.fs.dirs.DownloadDir +
                  "/" +
                  date +
                  ".txt";
        logsArray = [];
        // send mail logic here
    })
