Static Functions

Name	Description
`isConstruct`	Checks if `x` is a construct.
`isComponent`	Test whether the given construct is a component.

`isConstruct`

import { python } from 'projen'

python.Pip.isConstruct(x: any)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Adds an override to the synthesized object file.

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example,

project.tsconfig.file.addOverride('compilerOptions.alwaysStrict', true);
project.tsconfig.file.addOverride('compilerOptions.lib', ['dom', 'dom.iterable', 'esnext']);

would add the overrides

"compilerOptions": {
  "alwaysStrict": true,
  "lib": [
    "dom",
    "dom.iterable",
    "esnext"
  ]
  ...
}
...

`value`^Required

Type: any

The value.

Could be primitive or complex.

`addToArray`

public addToArray(path: string, values: ...any[]): void

Adds to an array in the synthesized object file.

If the array is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example, with the following object file

"compilerOptions": {
  "exclude": ["node_modules"],
  "lib": ["es2020"]
  ...
}
...

project.tsconfig.file.addToArray('compilerOptions.exclude', 'coverage');
project.tsconfig.file.addToArray('compilerOptions.lib', 'dom', 'dom.iterable', 'esnext');

would result in the following object file

"compilerOptions": {
  "exclude": ["node_modules", "coverage"],
  "lib": ["es2020", "dom", "dom.iterable", "esnext"]
  ...
}
...

`path`^Required

Type: string

`values`^Required

Type: ...any[]

The values to add.

Could be primitive or complex.

`patch`

public patch(patches: ...JsonPatch[]): void

Applies an RFC 6902 JSON-patch to the synthesized object file. See https://datatracker.ietf.org/doc/html/rfc6902 for more information.

For example, with the following object file

"compilerOptions": {
  "exclude": ["node_modules"],
  "lib": ["es2020"]
  ...
}
...

project.tsconfig.file.patch(JsonPatch.add("/compilerOptions/exclude/-", "coverage"));
project.tsconfig.file.patch(JsonPatch.replace("/compilerOptions/lib", ["dom", "dom.iterable", "esnext"]));

would result in the following object file

"compilerOptions": {
  "exclude": ["node_modules", "coverage"],
  "lib": ["dom", "dom.iterable", "esnext"]
  ...
}
...
