CGnal Network utils
Network utilities for CGnal's JavaScript projects.
Documentation.
The API documentation is published here.
Installation and usage
npm install @cgnal/net --save
The library doesn't come with a predefined build, but rather relies on the application that uses it to "set the rules".
@babel/runtime-corejs3
and core-js
are set as dependencies, so you can make your application build it for your intended targets and eventually add automatically the necessary polyfills.
Example of possible babel configuration:
// ...
"presets": [
["@babel/preset-env", {
"corejs": "3.19",
"modules": "auto",
"useBuiltIns": "usage"
}]
],
"plugins": [
["@babel/plugin-transform-runtime", { "corejs": 3, "proposals": true }],
]
// ...
Usage with Jest
Jest currently (v27.4.2 at the time of writing) doesn't play nice with ES modules and package.json
exports. See this issue about the exports support status.
Both problems are easily solved for the time being with a config tweak and, optionally, the support of jest-node-exports-resolver
.
Example of Jest configuration without an extra resolver:
// ...
moduleNameMapper: {
"@cgnal/([^/]+)/(.+)": "<rootDir>/node_modules/@cgnal/$1/src/$2"
},
transformIgnorePatterns: ["node_modules/(?!@cgnal)"],
// ...
Example of Jest configuration with the extra resolver:
// ...
resolver: "jest-node-exports-resolver",
transformIgnorePatterns: ["node_modules/(?!@cgnal)"],
// ...
eslint-plugin-import
Usage with eslint-plugin-import
still have to support the aforementioned exports field.
You can refer to this issue to track the situation.
In the meanwhile you can add a custom resolver such as @tophat/eslint-import-resolver-require
and tweak your configuration to use it:
// ...
"settings": {
"import/resolver": "@tophat/eslint-import-resolver-require"
}
// ...
NPM scripts and Gulp tasks
Only a few Gulp tasks are exposed as npm scripts, as such scripts are only a facilitation to run tasks without having to install gulp-cli
as a global module.
Running tasks in a CI server, for example.
If you want to use gulp
from the command line, you should npm install gulp-cli -g
first, or, to avoid installing it, prefix your commands with npx
, e.g. npx gulp test
.
