13 | 
14 | ## Installation
15 | Run the `npm install header-generator` command. No further setup is needed afterwards.
16 | ## Usage
17 | To use the generator, you need to create an instance of the `HeaderGenerator` class which is exported from this package. Constructor of this class accepts a `HeaderGeneratorOptions` object, which can be used to globally specify what kind of headers you are looking for: 
18 | ```js
19 | const { HeaderGenerator } = require('header-generator');
20 | let headerGenerator = new HeaderGenerator({
21 |         browsers: [
22 |             {name: "firefox", minVersion: 80},
23 |             {name: "chrome", minVersion: 87},
24 |             "safari"
25 |         ],
26 |         devices: [
27 |             "desktop"
28 |         ],
29 |         operatingSystems: [
30 |             "windows"
31 |         ]
32 | });
33 | ```
34 | You can then get the headers using the `getHeaders` method, either with no argument, or with another `HeaderGeneratorOptions` object, this time specifying the options only for this call (overwriting the global options when in conflict) and using the global options specified beforehands for the unspecified options:
35 | ```js
36 | let headers = headersGenerator.getHeaders({
37 |         operatingSystems: [
38 |             "linux"
39 |         ],
40 |         locales: ["en-US", "en"]
41 | });
42 | ```
43 | This method always generates a random realistic set of headers, excluding the request dependant headers, which need to be filled in afterwards. Since the generation is randomized, multiple calls to this method with the same parameters can generate multiple different outputs.
44 | 
45 | ## Presets
46 | Presets are setting templates for common use cases. It saves time writing the same configuration over and over.
47 | ```js
48 | const { HeaderGenerator, PRESETS } = require('header-generator');
49 | let headerGenerator = new HeaderGenerator(PRESETS.MODERN_WINDOWS_CHROME);
50 | ```
51 | 
52 | This preset will fill the configuration for the latest five versions of chrome for windows desktops. Checkout the available presets list here @TODO: LINK.
53 | ## Result example
54 | A result that can be generated for the usage example above:
55 | ```json
56 | {
57 |   "sec-ch-ua-mobile": "?0",
58 |   "user-agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.72 Safari/537.36",
59 |   "accept-encoding": "gzip, deflate, br",
60 |   "accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9",
61 |   "upgrade-insecure-requests": "1",
62 |   "accept-language": "en-US,en;0.9",
63 |   "sec-fetch-site": "same-site",
64 |   "sec-fetch-mode": "navigate",
65 |   "sec-fetch-user": "?1",
66 |   "sec-fetch-dest": "document"
67 | }

  1 | # (DEPRECATED) Header generator
  2 | 
  3 | ---

  5 | **DEPRECATED** The `header-generator` package now lives in the [fingerprint-suite](https://github.com/apify/fingerprint-suite) repository. This repository is no longer actively maintained.
  6 | 
  7 | ---
  8 | 
  9 | NodeJs package for generating browser-like headers.

 18 | 
 19 | <!-- tocstop -->
 20 | 
 21 | ## Installation
 22 | Run the `npm install header-generator` command. No further setup is needed afterwards.
 23 | ## Usage
 24 | To use the generator, you need to create an instance of the `HeaderGenerator` class which is exported from this package. Constructor of this class accepts a `HeaderGeneratorOptions` object, which can be used to globally specify what kind of headers you are looking for: 
 25 | ```js
 26 | const { HeaderGenerator } = require('header-generator');
 27 | let headerGenerator = new HeaderGenerator({
 28 |         browsers: [
 29 |             {name: "firefox", minVersion: 80},
 30 |             {name: "chrome", minVersion: 87},
 31 |             "safari"
 32 |         ],
 33 |         devices: [
 34 |             "desktop"
 35 |         ],
 36 |         operatingSystems: [
 37 |             "windows"
 38 |         ]
 39 | });
 40 | ```
 41 | You can then get the headers using the `getHeaders` method, either with no argument, or with another `HeaderGeneratorOptions` object, this time specifying the options only for this call (overwriting the global options when in conflict) and using the global options specified beforehands for the unspecified options:
 42 | ```js
 43 | let headers = headersGenerator.getHeaders({
 44 |         operatingSystems: [
 45 |             "linux"
 46 |         ],
 47 |         locales: ["en-US", "en"]
 48 | });
 49 | ```
 50 | This method always generates a random realistic set of headers, excluding the request dependant headers, which need to be filled in afterwards. Since the generation is randomized, multiple calls to this method with the same parameters can generate multiple different outputs.
 51 | 
 52 | ## Presets
 53 | Presets are setting templates for common use cases. It saves time writing the same configuration over and over.
 54 | ```js
 55 | const { HeaderGenerator, PRESETS } = require('header-generator');
 56 | let headerGenerator = new HeaderGenerator(PRESETS.MODERN_WINDOWS_CHROME);
 57 | ```
 58 | 
 59 | This preset will fill the configuration for the latest five versions of chrome for windows desktops. Checkout the available presets list [here](https://github.com/apify/header-generator/blob/master/src/presets.ts).
 60 | ## Result example
 61 | A result that can be generated for the usage example above:
 62 | ```json
 63 | {
 64 |   "sec-ch-ua-mobile": "?0",
 65 |   "user-agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.72 Safari/537.36",
 66 |   "accept-encoding": "gzip, deflate, br",

 39 | 
 40 |       "Derivative Works" shall mean any work, whether in Source or Object
 41 |       form, that is based on (or derived from) the Work and for which the
 42 |       editorial revisions, annotations, elaborations, or other modifications

 61 | 
 62 |       "Contributor" shall mean Licensor and any individual or Legal Entity

 72 | 
 73 |    3. Grant of Patent License. Subject to the terms and conditions of
 74 |       this License, each Contributor hereby grants to You a perpetual,

 76 |       (except as stated in this section) patent license to make, have made,
 77 |       use, offer to sell, sell, import, and otherwise transfer the Work,
 78 |       where such license applies only to those patent claims licensable
 79 |       by such Contributor that are necessarily infringed by their
 80 |       Contribution(s) alone or by combination of their Contribution(s)
 81 |       with the Work to which such Contribution(s) was submitted. If You
 82 |       institute patent litigation against any entity (including a
 83 |       cross-claim or counterclaim in a lawsuit) alleging that the Work
 84 |       or a Contribution incorporated within the Work constitutes direct
 85 |       or contributory patent infringement, then any patent licenses
 86 |       granted to You under this License for that Work shall terminate
 87 |       as of the date such litigation is filed.
 88 | 
 89 |    4. Redistribution. You may reproduce and distribute copies of the
 90 |       Work or Derivative Works thereof in any medium, with or without
 91 |       modifications, and in Source or Object form, provided that You
 92 |       meet the following conditions:
 93 | 
 94 |       (a) You must give any other recipients of the Work or
 95 |           Derivative Works a copy of this License; and
 96 | 
 97 |       (b) You must cause any modified files to carry prominent notices
 98 |           stating that You changed the files; and
 99 | 
100 |       (c) You must retain, in the Source form of any Derivative Works
101 |           that You distribute, all copyright, patent, trademark, and
102 |           attribution notices from the Source form of the Work,
103 |           excluding those notices that do not pertain to any part of
104 |           the Derivative Works; and
105 | 
106 |       (d) If the Work includes a "NOTICE" text file as part of its
107 |           distribution, then any Derivative Works that You distribute must
108 |           include a readable copy of the attribution notices contained
109 |           within such NOTICE file, excluding those notices that do not
110 |           pertain to any part of the Derivative Works, in at least one
111 |           of the following places: within a NOTICE text file distributed
112 |           as part of the Derivative Works; within the Source form or
113 |           documentation, if provided along with the Derivative Works; or,
114 |           within a display generated by the Derivative Works, if and
115 |           wherever such third-party notices normally appear. The contents
116 |           of the NOTICE file are for informational purposes only and
117 |           do not modify the License. You may add Your own attribution
118 |           notices within Derivative Works that You distribute, alongside
119 |           or as an addendum to the NOTICE text from the Work, provided
120 |           that such additional attribution notices cannot be construed
121 |           as modifying the License.
122 | 
123 |       You may add Your own copyright statement to Your modifications and
124 |       may provide additional or different license terms and conditions
125 |       for use, reproduction, or distribution of Your modifications, or
126 |       for any such Derivative Works as a whole, provided Your use,
127 |       reproduction, and distribution of the Work otherwise complies with
128 |       the conditions stated in this License.
129 | 
130 |    5. Submission of Contributions. Unless You explicitly state otherwise,
131 |       any Contribution intentionally submitted for inclusion in the Work
132 |       by You to the Licensor shall be under the terms and conditions of
133 |       this License, without any additional terms or conditions.
134 |       Notwithstanding the above, nothing herein shall supersede or modify
135 |       the terms of any separate license agreement you may have executed
136 |       with Licensor regarding such Contributions.
137 | 
138 |    6. Trademarks. This License does not grant permission to use the trade
139 |       names, trademarks, service marks, or product names of the Licensor,
140 |       except as required for reasonable and customary use in describing the
141 |       origin of the Work and reproducing the content of the NOTICE file.
142 | 
143 |    7. Disclaimer of Warranty. Unless required by applicable law or
144 |       agreed to in writing, Licensor provides the Work (and each
145 |       Contributor provides its Contributions) on an "AS IS" BASIS,
146 |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147 |       implied, including, without limitation, any warranties or conditions
148 |       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149 |       PARTICULAR PURPOSE. You are solely responsible for determining the
150 |       appropriateness of using or redistributing the Work and assume any
151 |       risks associated with Your exercise of permissions under this License.
152 | 
153 |    8. Limitation of Liability. In no event and under no legal theory,
154 |       whether in tort (including negligence), contract, or otherwise,
155 |       unless required by applicable law (such as deliberate and grossly
156 |       negligent acts) or agreed to in writing, shall any Contributor be
157 |       liable to You for damages, including any direct, indirect, special,
158 |       incidental, or consequential damages of any character arising as a
159 |       result of this License or out of the use or inability to use the
160 |       Work (including but not limited to damages for loss of goodwill,
161 |       work stoppage, computer failure or malfunction, or any and all
162 |       other commercial damages or losses), even if such Contributor
163 |       has been advised of the possibility of such damages.
164 | 
165 |    9. Accepting Warranty or Additional Liability. While redistributing
166 |       the Work or Derivative Works thereof, You may choose to offer,
167 |       and charge a fee for, acceptance of support, warranty, indemnity,
168 |       or other liability obligations and/or rights consistent with this
169 |       License. However, in accepting such obligations, You may act only
170 |       on Your own behalf and on Your sole responsibility, not on behalf
171 |       of any other Contributor, and only if You agree to indemnify,
172 |       defend, and hold each Contributor harmless for any liability
173 |       incurred by, or claims asserted against, such Contributor by reason
174 |       of your accepting any such warranty or additional liability.
175 | 
176 |    END OF TERMS AND CONDITIONS
177 | 
178 |    APPENDIX: How to apply the Apache License to your work.
179 | 
180 |       To apply the Apache License to your work, attach the following
181 |       boilerplate notice, with the fields enclosed by brackets "[]"

184 |       comment syntax for the file format. We also recommend that a
185 |       file or class name and description of purpose be included on the
186 |       same "printed page" as the copyright notice for easier
187 |       identification within third-party archives.
