Not getting replaced using the sed using the sed -i command

Question

I am trying to do the following thing using the sed

 cp src/config/template.js src/config/index.js

export API_GATEWAY_ENDPOINT="http://localhost:9000/"

sed -i "" "s|{{API_GATEWAY_ENDPOINT}}|$API_GATEWAY_ENDPOINT|g" src/config/index.js

But when I run this script, then I am getting this error,

sed: can't read s|{{API_GATEWAY_ENDPOINT}}|http://localhost:9000/|g: No such file or directory

I am using a Linux machine.

Can any tell me why this is happening?

The first argument to sed should be the script. So when you have that extra "", the second argument is interpreted as a file name.

And you don't need to copy the file and then do an inplace replacement. Instead use > operator to redirect the output from sed to the proper file.

>src/config/index.js <src/config/template.js sed "s|{{API_GATEWAY_ENDPOINT}}|$API_GATEWAY_ENDPOINT|g"
