Currently trying to download image from GitHub locally. Everything seems to work, the fetch goes through with a 200 OK response, however, I don't understand how to store image itself:

const rawGitLink = "https://raw.githubusercontent.com/cardano-foundation/CIPs/master/CIP-0001/CIP_Flow.png" 

const folder = "/Folder"
const imageName = "/Test"
const imageResponse = await axios.get(rawGitLink)


 fs.writeFileSync(___dirname   folder   imageName, imageResponse, (err) => {
   //Error handling                    
 }
)

CodePudding user response：

Four problems had to be fixed:

• Image name must include png format for this case
• The response must be in the correct format as a buffer for an image
• You must write the response data and not the object itself
• __dirname only needs two underscores

const rawGitLink = "https://raw.githubusercontent.com/cardano-foundation/CIPs/master/CIP-0001/CIP_Flow.png"

const folder = "/Folder"
const imageName = "/Test.png"
const imageResponse = await axios.get(rawGitLink, { responseType: 'arraybuffer' });

fs.writeFileSync(__dirname   folder   imageName, imageResponse.data)

CodePudding user response：

Axios returns a special object: https://github.com/axios/axios#response-schema

let {data} = await axios.get(...)
await fs.writeFile(filename, data) // you can use fs.promises instead of sync

As @Leau said you should include the extension on the filename Another sugestion is to use the path module to create the filename:

filename = path.join(__dirname, "/Folder", "Test.png")
