QUESTION
I am trying to install node_modules for my project, but instead of loading the libraries in package.json, npm install the latest ones. Before I used the command npm to install -g npm@latest, did it have any effect?
I tried npm install --force, npm install --legacy-peer-deps, and remove node but it has same error
My package.
ANSWER
Answered 2021-Apr-07 at 03:18The caret ^ means it can install the most recent compatible version. If you want it to install a specific version, you can remove the ^ in front of the versions.
See package.json docs and semver
The caret will let it install a later version that doesn't change the first number. For instance your package.json specifies ^4.0.0 for @ant-design/icons, but it installed 4.6.2. Since the 4 didn't change, that is acceptable.
QUESTION
I have read Excel file by Node js using npm: read-excel-file. But the date format is a float data type. I have tried many ways but some days it works and some do not. Incorrect date example below variable _num .
Excel Date data is true : 15/01/2021 10:12:16 SA but code return is : 2021-1-18 6:5:49
Please help me !!!
...ANSWER
Answered 2021-Jan-15 at 08:31Excel dates are stored as the number of days from the Excel epoch (December 31st 1899 / Jan 0 1900, see https://en.wikipedia.org/wiki/Epoch_(computing)) )
25569 is the number of days between the Excel epoch and the Unix epoch (1970-01-01), including an adjustment for the Excel leap year bug.
So, to get Unix time (milliseconds since 1970-1-1) we subtract 25569 from the excel date, then multiply by the number of milliseconds in a day.

I am trying to get some data from the database with async/await then create an object with some of the data and insert into the database. I need the calls to be synchronous for this in order to send complete data for insertion.
I have an async function but the await is not working...
The code is below:
...ANSWER
Answered 2020-Dec-11 at 20:02it shows this error "await is only valid in async function". I except to get the roleId here and create the object below with that role id.
Your use of await is inside the nested .then() handler callback which is not itself async.
In general, you don't want to mix .then() and await within the same control-flow. I would suggest you change it to this:
QUESTION
In my Node JS / Express JS project, I need to get an excel project and I will be using this library read-excel-file.
I need to get the file path in order to continue with this code from the library documentation:
...ANSWER
Answered 2020-Oct-28 at 21:22You CAN NOT access file on client file system from an HTTP server. You will need to send the file from client to server.
There's a lot of resource available online which can help with file upload but the gist is that file is send as a multipart-data from client to server. In Express server, multer module is used to access the file in req.file property.

I have bit of confusion regarding the reading of file using HTML, AngularJS and Node.js. Since I am bit confused I am hoping someone can guide me with this.
I am trying to import a file using HTML and Angularjs and it is working fine. I am able to import a file but I am not sure how can I send the whole file to Node.js.

QUESTION
My task is to copy the range F1:F200 from several thousand Excel files, and paste them into adjacent columns in the destination folder. The macro works, but it takes about 5 seconds for each file to open.
I thought about the "Get Data" query function, but I'm not familiar with it. I couldn't even determine if it's possible to import a single range and paste it where you need it.
Are there other methods of speeding up the process?
(I saw this post: Read Excel file without opening it and copy contents on column first blank cell, but I cannot attempt it for another 12 hours. I'm hoping that by then, someone will tell me that it's definitely faster, or definitely slower, or something.)
EDIT: I thought saying "open, copy, and paste" was sufficient description of the process, but it's probalby better to show you:

Answered 2018-Dec-17 at 09:41This should be a little faster

If you do the following, similar to your code above, you can retrieve the file correctly:
QUESTION
I'm trying to upload and read excel file using this node module: read-excel-file and according to the instructions under Browser I need to put this code in my .js file:
...ANSWER
Answered 2018-Aug-23 at 12:15TL;DR: You have to actually compile your js code into broswer usable code. Use bower, webpack or other bundling tools to do so.
Long story: The browser does not understand import (because for example: where is the resource?). You can use tools like bower or webpack to create bundles of javascript code that detect on compile time that import XX from YY means that they have to look in de node_modules or bower_modules folder for that module and include it in the final bundle
PS: Be aware that not all npm modules are able to run in the browser since thy are node modules or vise versa (they provide different API's).
