How to clear browser local stored data?

• Platform: browser
• Subsystem: files

Type: Question

Severity: Low

Description:

I want to clear some of the data stored in the browser by ipfs, preventing excessive data usage and causing possible exceptions. But the ipfs.repo.gc interface is not implemented, then I use ipfs.files.rm, but how do I change it?

For example, I want to delete QmZdXoMy8Gvis99qmGtHH4Q8YaUTwZrC5G7hRiLcMwrnVk and all leaf nodes, call ipfs.files.rm('/ipfs/QmZdXoMy8Gvis99qmGtHH4Q8YaUTwZrC5G7hRiLcMwrnVk', {recursive: true}) will report an error.

Steps to reproduce the error:

> await ipfs.files.stat('/ipfs/QmZdXoMy8Gvis99qmGtHH4Q8YaUTwZrC5G7hRiLcMwrnVk', {withLocal: true})
{
  blocks: 0,
  cumulativeSize: 107507,
  hash: "QmZdXoMy8Gvis99qmGtHH4Q8YaUTwZrC5G7hRiLcMwrnVk",
  local: undefined,
  size: 107493,
  sizeLocal: undefined,
  type: "file",
  withLocality: false
}

> await ipfs.files.rm('/ipfs/QmZdXoMy8Gvis99qmGtHH4Q8YaUTwZrC5G7hRiLcMwrnVk', {recursive: true})

ipfs.files.rm operates on the Mutable File System (MFS). You cannot use it to delete an IPFS object by CID, like '/ipfs/QmZdXoMy8Gvis99qmGtHH4Q8YaUTwZrC5G7hRiLcMwrnVk'

@bruinxs Chrome中按F12进Application标签, 数据应该在IndexedDB中. 所以清除IndexedDB即可, 或者清楚浏览器缓存.

@alx696 Thank you, but I hope to automatically erase unused data in the production environment.

Just to reiterate what @reasv said, files.rm is for removing files from your MFS tree not for removing blocks from your repo. Garbage collection is what you need for this and it is being worked on right now. You can follow progress here #2012
