Update a single cell of Google Sheets using JavaScript API

Question

I've followed this tutorial and I am able to successfully get it working to "get" data from the spreadsheet, but now I would like to update a single cell using just the JavaScript API. I'm trying to use this JS method:

    gapi.client.sheets.spreadsheets.values.update({
      spreadsheetId: 'something',
      range: 'Sheet1!B2',
    })

But I'm not quite sure how to pass in the new cell value into the Request body. I've tried my best to follow this as a guide but I'm not quite sure how to use this. I can't find any documentation around "gapi.client.sheets.spreadsheets.values.update" JavaScript API. I get 400 errors back from the API with anything I've tried.

Answer 1

gapi.client.sheets.spreadsheets.values.update({
    spreadsheetId: 'something',
    range: 'Sheet1!B2',
    valueInputOption: 'USER_ENTERED',
    values: [ ["123"] ]
}).then(function(response) {
    console.log(response);
});

Answer 2

I think google updated their API because Tim's answer didn't work for me. Here is my structure:

let spreadsheetId = "idOfMySheet";
let range = "nameOfSheet!A1";
let valueInputOption = "RAW";
let myValue = 5;

let values = [[myValue]];
let resource = {
    values,
};
sheets.spreadsheets.values.update({
    spreadsheetId,
    range,
    valueInputOption,
    resource
}, (err, result) => {
    if (err) {
        console.log(err);
    } else {
        console.log('%d cells updated.', result.updatedCells);
    }
});
