Using NPM to manage dependencies ​

AirCode provides a visual way to management NPM dependencies, operations like searching, installing, upgrading and uninstalling packages are all completed by clicking without entering any commands.

Install Dependencies ​

Dependency management is located in the Dependencies area below the function list. Enter the name and search in the input box, such as lodash, then click the corresponding dependency package to install the latest version.

If you want to install other versions, you can click the icon on the right side of the search box, or click View All Search Results, and select a specific version in the pop-up window.

After the installation, it can be imported and used in cloud functions. For example, create a function called npm.js and modify it to the following code:

// Require the dependency `lodash`
const _ = require('lodash');

module.exports = async function(params, context) {
  // Call methods of the dependency
  const lodashVersion = _.VERSION;
  const partition = _.partition([1, 2, 3, 4], n => n % 2);
  return {
    lodashVersion,
    partition,
  };
}

// Require the dependency `lodash`
const _ = require('lodash');

module.exports = async function(params, context) {
  // Call methods of the dependency
  const lodashVersion = _.VERSION;
  const partition = _.partition([1, 2, 3, 4], n => n % 2);
  return {
    lodashVersion,
    partition,
  };
}

Click Debug to see the return result:

{
  "lodashVersion": "4.17.21",
  "partition": [
    [ 1, 3 ],
    [ 2, 4 ]
  ]
}

{
  "lodashVersion": "4.17.21",
  "partition": [
    [ 1, 3 ],
    [ 2, 4 ]
  ]
}

Deploy Dependencies ​

In order to ensure stable online running, the installed dependencies only take effect locally. If you want the dependency to take effect online as well, just deploy the function.

For example, after deploying npm.js in the above example, invoke it via curl:

curl https://sample.hk.aircode.run/npm

curl https://sample.hk.aircode.run/npm

You will get below result：

{
  "lodashVersion": "4.17.21",
  "partition": [
    [ 1, 3 ],
    [ 2, 4 ]
  ]
}

{
  "lodashVersion": "4.17.21",
  "partition": [
    [ 1, 3 ],
    [ 2, 4 ]
  ]
}

It means the dependency is deployed successfully online.

Upgrade and Uninstall Dependency ​

When the mouse hovers over an installed dependency, an operation button will appear on the right, allowing you to quickly upgrade the version or delete it.

Among them, Upgrade to latest will update the package to the latest official version currently released, and any unofficial versions such as alpha, beta, rc will be ignored.

If you want to install a specific version, please re-Search and Install the Dependency.
