Escape dot character ['.'] on path for mutateIn operations


Hi, I need to insert a key-value pair on a doc on which the key string contains dots, the problem is that the insert method of the mutateIn builder interprets the key as the path and therefore, instead of creating a single key-value pair, it creates a tree.

Example, this code:

const key   = 'perfmon.phy_disk.pct_disk_read_time';
const value = 123;

      .insert(key, value)
      .execute(err => {

Creates this doc:

    perfmon: {
      phy_disk: {
        pct_disk_read_time: 123

What I want to obtain is instead:

    perfmon.phy_disk.pct_disk_read_time: 123

Is there a way to escape the dot char for the insert operation?

Thanks in advance,


Yes there is - see


Thanks a lot Dave, this solved the problem. It would be very handy to have at least a link or reference to this documentation at the Node.js SDK page as it does’t mention it at all.

Thanks again!
