Ive actually been running through a bunch of the different js-ipfs examples and keep getting this same response... Currently following IPFS 101 which has some different code (at least in the 'cat' section) will let you know the results. Maybe try to change the 'cat' section with this code...

node.files.cat(fileMultihash, (err, data) => {
  if (err) { return cb(err) }

  console.log('\nFile content:')
  // print the file to the terminal and then exit the program
  process.stdout.write(data)
})

Hi there! The issue you are seeing is because the browser-script-tag example always uses the released version and we have one release in the works that has API changes #1095

Once the release is done you won't experience any more problems. If you want to try the example prepared for 0.26, you can check it out on the release tag https://github.com/ipfs/js-ipfs/releases/tag/v0.26.0

Getting:
Uncaught TypeError: Cannot read property 'put' of undefined
Uncaught TypeError: Cannot read property 'get' of undefined

As Errors when I try to something with the code provided in the html.
Any suggestions ?

Hi @davidak @JohannesKnecht @debrayc , you can now try again the example. With js-ipfs 0.27.0 released, the examples on master are up to date. Let me know how it goes!

@diasdavid Now another error is showing up:

There is a current known issue with the minified version, see more here: #1136

Meanwhile, use the non minified version to go over this issue -- https://github.com/ipfs/js-ipfs#use-in-the-browser
