Sometimes, we want to make Axios send cookies in its requests automatically.

In this article, we’ll look at how to make Axios send cookies in its requests automatically.

How to make Axios send cookies in its requests automatically?

To make Axios send cookies in its requests automatically, we can set the withCredentials option to true.

For instance, we write

axios.get(BASE_URL + '/todos', {
  withCredentials: true
});

to call axios.get with an object that has withCredentials set to true to send the cookie with the request to BASE_URL + '/todos'.

Conclusion

To make Axios send cookies in its requests automatically, we can set the withCredentials option to true.

Sometimes, we want to sort in Node.js Mongoose.

In this article, we’ll look at how to sort in Node.js Mongoose.

How to sort in Node.js Mongoose?

To sort in Node.js Mongoose, we can use the sort method.

For instance, write:

Post.find({}).sort('test').exec((err, docs) => {
  //...
});

to call sort with the property to sort by.

We can sort descending with

Post.find({}).sort([
  ['date', -1]
]).exec((err, docs) => {
  //...
});

We call sort with a nested array with the property name and -1.

The exec callback is run when the sorting is done.

docs has the sorted data.

Conclusion

To sort in Node.js Mongoose, we can use the sort method.

Sometimes, we want to fix the ‘Error: failed to serialize user into session’ error with Passport.js.

In this article, we’ll look at how to fix the ‘Error: failed to serialize user into session’ error with Passport.js.

How to fix the ‘Error: failed to serialize user into session’ error with Passport.js?

To fix the ‘Error: failed to serialize user into session’ error with Passport.js, we use the serializeUser and deserializeUser methods.

For instance, we write

passport.serializeUser((user, done) => {
  done(null, user);
});

passport.deserializeUser((user, done) => {
  done(null, user);
});

to call serializeUser with a callback to serialize the user data.

The callback is run when the operation is done.

We call deserializeUser with a callback to serialize the user data.

The callback is run when the operation is done.

We call done to indicate the operation is done

Conclusion

To fix the ‘Error: failed to serialize user into session’ error with Passport.js, we use the serializeUser and deserializeUser methods.

Sometimes, we want to copy a folder recursively in Node.js.

In this article, we’ll look at how to copy a folder recursively in Node.js.

How to copy a folder recursively in Node.js?

To copy a folder recursively in Node.js, we can use the copySync method from the fs-extra module.

For instance, we write

const fse = require('fs-extra');

const srcDir = `path/to/file`;
const destDir = `path/to/destination/directory`;

fse.copySync(srcDir, destDir, {
  overwrite: true
}, (err) => {
  if (err) {
    console.error(err);
  } else {
    console.log("success!");
  }
});

to call copySync with the source srcDir path, the destination destDir path, and an object with overwrite set to true to overwrite any existing files with the same name, and a callback that runs when copySync is done.

If there’re any errors, err will be set.

Conclusion

To copy a folder recursively in Node.js, we can use the copySync method from the fs-extra module.

Sometimes, we want to make a remote REST call with Node.js.

In this article, we’ll look at how to make a remote REST call with Node.js.

How to make a remote REST call with Node.js?

To make a remote REST call with Node.js, we can use axios.

We install it by running

npm i axios

Then we use it by writing

const url = `https://example.com`;

const {
  data
} = await axios({
  method: 'get',
  url,
})

to call axios with the 'get' request method and the request url.

It returns a promise with the response data stored in data.

Conclusion

To make a remote REST call inside Node.js, we can use axios.
